The UV index scale

UV index	Level
0–2	Low Low danger from the sun's UV rays for the average person. Wear sunglasses on bright days. If you burn easily, cover up and use broad-spectrum SPF 30+ sunscreen. Sand, water and snow reflect UV and add to your exposure.
3–5	Moderate Moderate risk from unprotected sun exposure. Stay in the shade near midday, when the sun is strongest. Wear protective clothing, a wide-brimmed hat and UV-blocking sunglasses, and apply broad-spectrum SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating.
6–7	High High risk from unprotected sun exposure: skin and eyes need protection. Reduce time in the sun around the middle of the day, seek shade, and wear protective clothing, a wide-brimmed hat, UV-blocking sunglasses and broad-spectrum SPF 30+ sunscreen, reapplied every 2 hours.
8–10	Very high Very high risk: unprotected skin and eyes can be damaged and burn quickly. Minimize time in the sun around the middle of the day, seek shade, and cover up with clothing, a wide-brimmed hat, UV-blocking sunglasses and broad-spectrum SPF 30+ sunscreen, reapplied every 2 hours.
11+	Extreme Extreme risk: unprotected skin and eyes can burn in minutes. Try to avoid the sun around the middle of the day, stay in the shade, and use every protection: clothing, a wide-brimmed hat, UV-blocking sunglasses and broad-spectrum SPF 30+ sunscreen, reapplied every 2 hours.
