The UV Index is a standard measurement of the strength of sunburn-producing ultraviolet (UV) radiation at a particular place and time. Our live tracker helps you practice proper sun safety by providing real-time data and localized forecasts based on your exact location.
The Sun Safety Risk Scale
0-2 (Low): Minimal danger for the average person. Wear sunglasses on bright days.
3-5 (Moderate): Low risk of harm. Apply SPF 30+ sunscreen every 2 hours and wear protective clothing if outside.
6-7 (High): High risk of harm. Reduce time in the sun between 10 AM and 4 PM.
8-10 (Very High): Very high risk. Take extra precautions. Unprotected skin can burn quickly.
11+ (Extreme): Extreme risk of harm. Try to avoid sun exposure completely during peak midday hours.
