Fetching UV index…
How This Tool Works
This tool fetches the current UV index (and each of the next 5 days’ daily maximum) from Open-Meteo’s forecast API, for the city you search for. The reading is shown on a colored gauge and classified using the WHO’s own published Global Solar UV Index scale: Low (0–2), Moderate (3–5), High (6–7), Very High (8–10), and Extreme (11+) — these are the WHO’s real published numbers, not a scale invented for this site.
This tool shows general, published sun-safety guidance — it is not medical advice. If you have specific skin-health concerns, follow guidance from your local health authority or doctor.
FAQ
Why is there no UV reading at night?
UV index is driven directly by sunlight, so it is zero (or not reported) after dark. If you search a city where it’s currently nighttime, the tool will say so rather than showing a misleading number.
Where do the risk-level bands come from?
The World Health Organization’s Global Solar UV Index — a scale used worldwide by weather services. The exact bands and their guidance text are reproduced from WHO’s own published guidance, not invented for this site.
