Understanding UV in Idaho

UV levels across Idaho follow the same daily pattern everywhere: low in the early morning, a peak around midday, and a drop toward evening. How high the peak gets depends on the season, the sun's angle, elevation, and cloud cover. Southern and higher-elevation areas tend to see stronger midday UV than northern, lower ones.

Whatever the forecast, the safe habits are the same. Check the live reading for your city, cover up when the index hits 3 or more, and be extra careful with midday sun on high-UV days.
