Heya Folks.. This index may come as a surprise to many for existing at all. Several years back, I had been surprised to hear about so called 'sunshine warnings' in Australia....then discovered our own Government tracks and reports the same things on a daily basis.
Now this isn't about temperature, so it isn't strictly "sunshine" this is about. It's UltraViolet Light and what burns your skin. In fact, before looking at the current maps, take a look at the chart which gives meaning to the numbers....
This is a text description of it on the EPA Website.
In watching these in the past, the following isn't an unusual thing to see.
It varies, of course, and here is a better description of what UV is, overall...

This is today's map...
Remeber...purple and lighter are bad things. Whew......
Looks like a bad week to go sunbathing, unless being a little lobster sounds appealing.

The UV Index is a next day forecast of the amount of skin damaging UV radiation expected to reach the earth's surface at the time when the sun is highest in the sky (solar noon). The amount of UV radiation reaching the surface is primarily related to the elevation of the sun in the sky, the amount of ozone in the stratosphere, and the amount of clouds present. The UV Index can range from 0 (when it is night time) to 15 or 16 (in the tropics at high elevations under clear skies). UV radiation is greatest when the sun is highest in the sky and rapidly decreases as the sun approaches the horizon (Figure 1). The higher the UV Index, the greater the dose rate of skin damaging (and eye damaging) UV radiation. Consequently, the higher the UV Index, the smaller the time it takes before skin damage occurs (Figure 2).
