What today's level means

Today's peak of 3 is in the moderate band. The guidance for that band is: seek shade around midday, cover up and wear sunscreen. The EPA recommends protecting your skin whenever the index is 3 or higher, and you can burn even when it is cloudy.

The UV index depends mostly on how high the sun is in the sky, so it peaks around the middle of the day and is far higher in summer than in winter. It is not the same as temperature. For the full scale and what it means for tanning and burning, see what the UV index numbers mean.

UV tells you how strong the sun is, not whether it will be out. For that, see the sunshine forecast for Charleston.
