To add a clock and weather overlay to a 24/7 YouTube lofi stream, render both in a transparent web page and place that page over your scene with OBS Studio’s Browser Source. OBS displays the page; the page code or a provider supplies the clock and weather data.
A local page gives you control and avoids relying on a third-party overlay widget. A hosted page is easier to update remotely, but it depends on both hosting and a network connection. In either case, decide the location, timezone and units deliberately, and make sure the display has a graceful response when weather data cannot load.
Decide what the overlay should show
Treat the overlay as information on top of the lofi scene, not as a second visual attraction. A useful starting point is a readable local time, the city or region it refers to, the temperature and a short condition label. Wind can be useful for some listeners, but each extra line takes space and can compete with the scene. You do not need a hardware clock or weather station for this task: a page can render the clock and request weather data remotely.
Choose the time zone based on what the label promises. If the page says “Mumbai time”, its clock should use India Standard Time even if the streaming machine is elsewhere. If your channel serves listeners in a different place, make that city explicit rather than making viewers infer it from the temperature. A mismatch between location and time zone makes the display less useful than leaving the clock off.
Choose Celsius or Fahrenheit for the expected audience and keep the unit next to the value. A number without its unit is ambiguous, especially for viewers in different countries. Weather requests should specify a location as coordinates and specify a timezone and unit choice rather than relying on defaults. For example, Open-Meteo’s API reference documents latitude and longitude, current-weather fields, temperature units and a timezone parameter; its timezone default is GMT, while auto resolves one from the coordinates. See the Open-Meteo API documentation before building your request.
Use a short condition description rather than a detailed report. The page might show “22°C · cloudy” below “Bengaluru · local time”. Keep the wording honest: Open-Meteo describes its current conditions as based on 15-minute weather-model data, not a live reading from a sensor on the street. Refreshing the screen more often does not make the underlying model data more immediate.
This is a visual choice as much as a data choice. Put text over a reasonably quiet part of the artwork, use contrast that holds up over light and dark scenes, and preview it at the size a phone viewer will see. YouTube’s player controls can also cover parts of the image, so do not place essential text at the extreme edges. These are practical design checks, not guarantees about audience response.
Build a transparent clock-and-weather page
OBS Browser Source is a browser rendered inside an OBS scene. OBS Project describes it as “one of the most versatile sources available in OBS”; its Browser Source documentation explains that it can load a local file or a URL and lists source settings such as width, height and refresh behaviour. OBS is the renderer, not the weather provider. The page you load needs to implement the clock and make a weather request, or you can use a provider’s page if it allows the design and behaviour you need.
For a custom page, keep the responsibilities separate. The clock can use the page’s time functions with the chosen timezone. The weather part requests current conditions for the selected coordinates and displays a small set of fields. The layout places those values over a transparent background. This approach does not require a dedicated overlay product, although you can use a third-party page if you trust its availability and it exposes the settings and appearance your channel needs.
Write down the intended display before building it: location label, timezone, units, fields and how the page should behave when the weather request fails. A simple fallback is to keep the clock visible while hiding the stale weather value and showing when the last successful update occurred. That is an implementation choice for your page, not a recovery feature promised by OBS or the weather API.
Weather request details matter. Open-Meteo documents current-weather variables such as temperature, apparent temperature, weather code, precipitation, cloud cover and wind. Use only what the layout needs, and map the returned weather code to a concise human-readable description. If you use Open-Meteo commercially, check its current access and licensing terms: its API reference says an API key is required for commercial use of reserved API resources, which is not the same as saying every commercial use requires a key or that all use is free.
Test the page in a normal browser first. Check that the clock advances, that the weather request returns the expected place and units, and that a failed request does not leave an old value presented as current. Then check the page in OBS as well: browser rendering, fonts and viewport dimensions can differ from the page open on your desktop. If you do not want to write or maintain page code, a hosted overlay provider can supply the page, but it is optional rather than required.
Choose a local file or hosted page
OBS supports both a local page and a URL. The choice is mainly about who updates the page and what can interrupt it. A local file can be edited on the machine running OBS and does not rely on a separate overlay host to serve the page. A hosted page can be changed remotely, but the page must be reachable over the network and the host must continue serving it.
| Choice | What it suits | Dependency to account for |
|---|---|---|
| Local HTML file | You want to control the code and can update the streaming machine directly | The file must remain in place and its weather request still needs network access |
| Hosted web page | You want to revise the display remotely or use a provider’s configured page | Both network access and the host’s availability matter |
A local file does not make the entire overlay offline. Its clock can continue from the machine’s time source, but remotely fetched weather cannot refresh without a connection. Conversely, a hosted page cannot be assumed to work when the network is down: the page itself may fail to load, and its weather request may fail separately. Consider what viewers will see under each failure, rather than treating “local” as equivalent to “independent of the internet”.
If you maintain a local page, keep a copy of the source code somewhere you can retrieve it if the streaming machine changes. Make the file path stable and test it after moving the page. If you host the page, use a URL that does not change unexpectedly and check that it loads from the same machine and network as OBS. In both cases, avoid making a late design edit immediately before leaving a long broadcast unattended.
For a 24/7 channel, the page is only one part of the broadcast. YouTube distinguishes the incoming liveStream from the viewer-facing liveBroadcast; its guide to 24/7 live streaming explicitly discusses a continuous feed. That describes API resources and a setup pattern, not a promise that a particular stream will remain uninterrupted. If you are building the channel around pre-recorded material, the guide to starting a 24/7 YouTube stream from pre-recorded videos in India covers the larger continuous-stream setup separately.
Add it as an OBS Browser Source
Open the scene that contains your lofi artwork and add a Browser Source in the Sources panel. If you already have a background image or video source, keep the browser source above it in the source order so the page appears on top. Name the source clearly, such as “Clock and weather”, so you can find it later among other scene elements.
For a local page, enable the local-file option and select the HTML file. For a hosted page, enter its URL. Set the Browser Source width and height to the intended page viewport, not merely to the full canvas by habit. A compact overlay may need a narrower viewport than the stream canvas. OBS documents both local-file and URL modes and allows you to configure the source dimensions.
The source’s refresh controls are useful when testing or when a scene becomes active, but they are not a substitute for testing failure states. OBS offers controls for refreshing the page and for unloading it when hidden; their presence does not establish that a page will automatically recover from every failed request or run indefinitely without attention. Keep the source visible in the scene used for the continuous broadcast, and test any unload or refresh choices before relying on them.
Preview the scene after adding the source. If the page is blank, check the file path or URL first, then check the page itself in a browser. If the clock appears but the weather does not, the page may have loaded while its external request failed. That is a different problem from OBS failing to render the source. Distinguishing those cases makes troubleshooting quicker and helps avoid changing unrelated stream settings.
If your scene has several variants, add the source where it is needed and verify that its visibility is consistent. A source hidden in the live scene cannot be made visible by the page continuing to update. Keep a short pre-broadcast check in your operating notes, much as you would keep the OBS dropped-frames settings checklist for encoder and connection issues.
Set the viewport and position it
The Browser Source viewport is the page’s own layout area. Set its width and height to the dimensions you designed the page for, then place and scale the source in the scene. If you design a small card but give it a much larger viewport, the page can appear unexpectedly small or leave excess empty area. If you use a viewport that is too narrow, text may wrap or be clipped. Match the page’s design dimensions to the source and inspect the result in OBS.
Place the overlay where it does not obscure the subject of the artwork. Lofi scenes often have a window, desk, character or landscape that gives the image its identity; putting the clock across that focal area can make both the scene and text harder to read. Try a quiet corner, then review the composition at the actual output resolution and in a smaller preview. Text that looks clear on a large monitor may be too fine on a phone.
A stable position is usually better than animation for an always-on visual. Keep the card compact, avoid rapidly changing layout, and do not make the weather line expand or contract so much that the whole overlay jumps as conditions change. Reserve enough room for the longest city label and a plausible temperature format. Check both a short and long condition description before leaving the layout in service.
Keep player controls in mind. Viewers can pause, change volume or use other controls, and some interfaces cover portions of the video. Do not put the only location label or an important note exactly where a control is likely to sit. There is no single safe corner for every device and player layout, so inspect the stream on the devices your audience is most likely to use.
Keep the background transparent
The page must have a transparent background if the lofi artwork is to remain visible through the parts of the viewport not occupied by text. OBS Browser Source’s documented default CSS removes page margins, hides overflow and makes the background transparent. If your own page styles override those defaults, set the page and its root elements to transparent and avoid a full-page opaque colour. You can still give the text a subtle translucent panel if it improves legibility, but that panel should be limited to the information area rather than covering the scene.
Check transparency in the OBS preview, not only in a standalone browser. A browser tab may show a white page background even when the OBS source uses its documented default styling, while a custom page can also accidentally paint an opaque background. If the artwork disappears under a rectangle, inspect the page’s CSS for a background colour applied to the body or container. If the page edges cut off, check overflow and viewport dimensions.
Contrast matters against changing artwork. White text can disappear over a bright window; dark text can disappear over a night sky. Use a restrained outline, shadow or small backing panel if needed, then test it over the lightest and darkest parts of the loop. Avoid a large opaque block simply to solve a contrast problem that can be fixed with more careful placement or typography.
For broader scene design, the article on streaming nature sounds and meditation music without a black screen discusses keeping the visual presentation intentional. The same principle applies here: the overlay should support the scene, not make the stream look like a dashboard.
Check updates and network dependencies
A clock and weather line update in different ways. The clock can redraw from the page’s time source at a chosen interval. Weather is normally requested from an external data service and should be refreshed at a sensible cadence. Since Open-Meteo says its current conditions are based on 15-minute weather-model data, polling much more often does not mean the underlying condition is changing with that frequency or reflects a live street-level sensor reading. Choose an interval suited to the information rather than refreshing continuously.
Make the last successful weather update visible if you want viewers to understand when data is old. If a request fails, avoid silently leaving a temperature on screen as though it were current. You can hide the value, label it as stale, or show the time of the last successful request. Test the behaviour by temporarily making the request unavailable or using an invalid location during setup, then restore the correct request before going live.
There are at least two network paths to consider with a hosted page: loading the page from its host and retrieving weather data from the data provider. A local page removes the first dependency but not the second. A network interruption can therefore leave the clock running while weather is missing, or prevent the page from loading at all, depending on how it is hosted and implemented. The local/hosted choice is not a substitute for monitoring the overall stream connection.
Check the overlay after a real scene transition and after a source refresh. Watch for a frozen clock, a failed weather response, changed fonts, clipping or a background that has become opaque. Leave the page running in OBS for a practical test period before making it part of an unattended broadcast. This does not prove future uptime; it catches avoidable configuration problems before viewers encounter them.
Keep broadcast controls separate from overlay behaviour. YouTube exposes choices such as archive, DVR, auto-start, auto-stop and latency for broadcasts; the YouTube Live Streaming API lifecycle documentation explains these controls. Whether a long broadcast should be archived or restarted is a channel decision, not something a clock page decides. If you need a machine-side fallback plan, see how to keep a YouTube live stream running when OBS crashes. The overlay does not repair an encoder or YouTube broadcast interruption.
For a stream built from a fixed lofi video, a cloud-run broadcast can also remove the need to leave your own computer on just to repeat the file. StreamNeo can take away that specific machine-running burden while the overlay itself remains a page with its own location, data and network considerations. Keep the page’s behaviour and the broadcast’s health as two separate things to check.

FAQ
Does OBS provide the weather data?
No. OBS Browser Source displays a web page, but the page code or a provider has to supply the clock and weather behaviour. You need to configure a weather source and location yourself.
Does a hosted overlay work without an internet connection?
Do not assume so. A hosted page needs network access to load, and its weather request may need a separate connection to a data provider. A local page can avoid dependence on a page host, but remote weather data still needs a connection.
Should I refresh the weather as often as the clock?
Usually not. The clock can redraw frequently, while Open-Meteo’s documented current conditions are based on 15-minute weather-model data. Choose a weather refresh interval that avoids needless requests and show a fallback if the request fails.
Is a third-party overlay service required?
No. You can make a local HTML page or host your own page and use OBS Browser Source. A third-party provider is a convenience if it gives you a page and controls you want, not a requirement for placing a clock and weather display over a lofi scene.
