Arrow BulletUnderstanding the UV Index

The UV index is used to measure how strong the sun's ultraviolet (UV) radiation is on a particular day. The index is on a scale from 0 (very weak sun) to 11+ (extremely strong sun).

Listen to the daily UV index on the weather
forecast to plan your outdoor activities.

0 – 2 LOW Minimal protection required – use sunscreen,
sun-glasses and cover up if outside for more
than 1 hour.
3 – 5 MODERATE Wear a hat, sunglasses, sunscreen if outside
for 30 min. or more.  Look for shade when the
midday sun is strongest.
6 – 7 HIGH Protection required – reduce time in the sun
between 11 a.m. and 4 p.m.
8 – 10 VERY HIGH Extra precautions required – avoid the sun
between 11 a.m. and 4 p.m.
11+ EXTREME Unprotected skin can burn in minutes.
