About the UV Index
What is the UV index?
The UV index (UVI) is an international standard measure of the strength of ultraviolet radiation from the sun at a particular place and time. It ranges from 0 (nighttime) to 11+ (extreme). Higher values mean greater risk of sunburn, skin damage, and eye injury. The UV index was developed by the World Health Organization (WHO) to help people protect themselves from harmful UV radiation.
How do I check the UV index today?
This page shows the live UV index for your location using data from the Copernicus Atmosphere Monitoring Service (CAMS). You get the current UV level, an hourly UV forecast chart for today and tomorrow, and the exact peak UV time — so you always know when sun protection is most important.
When is UV radiation strongest?
UV radiation is typically strongest between 10:00 and 16:00, when the sun is highest in the sky. However, the exact peak time and intensity depend on your latitude, the season, altitude, cloud cover, and ozone levels. Check the UV forecast chart above to see today's exact peak time for your location.
How can I protect myself from UV radiation?
Apply sunscreen with appropriate SPF for your skin type, wear protective clothing and a wide-brimmed hat, seek shade during peak UV hours, and wear UV-blocking sunglasses. The WHO recommends extra caution when the UV index is 3 or above. Your needed protection level depends on the UV index and your Fitzpatrick skin type — use the skin type selector above for personalized advice.
What is the Fitzpatrick skin type?
The Fitzpatrick scale classifies skin into six types (I–VI) based on how it responds to UV exposure. Type I (very fair skin) burns easily and never tans, while Type VI (very dark skin) rarely burns. Knowing your Fitzpatrick type helps you estimate burn time and choose the right SPF level.
