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. |
