Pin the widget to a destination, fall back to a default, or auto-detect the visitor's own location.

Three polished styles

Editorial gradient, minimal stat grid, or circular sun-dial — all light/dark themed to match your brand.

Live + 5-day forecast

Hourly UV index plus burn-time guidance and a 5-day peak UV outlook.

Frequently asked

Is the widget really free?+

Yes. The widget is free for personal, editorial, educational, government, and commercial sites. The only requirement is that the small "Powered by Daily UV Tracker" link stays visible.

Do I need an API key or account?+

No. Paste a single <script> tag and the widget loads. There is no signup, no key, and no cookies set on your visitors.

Will it slow down my page?+

No. The loader is around 5 KB, loads async, and the widget is rendered in a lazy iframe so it never blocks rendering or Core Web Vitals.

Can I show the visitor's own UV instead of a fixed city?+

Yes. Switch to "Auto-detect" mode and the widget asks the browser for the visitor's location, falling back to a city you choose.

Where does the UV data come from?+

UV index, burn time, and 5-day forecasts come from public meteorological data. Risk categories follow the WHO UV index scale.
