UV Index Levels

Interesting that the UV index readings that I take regularly every day have been reading low (1.5 to 2)when the sky has been clear and temps around 40 over Canberra during the past few days. Also I have been working outside off and on during this time and have not been getting sunburnt??
So is the sun depleting in UV??

UV index is still only below middle of the road intensity.
09:45 sun at approx 50 degrees high, clear sky and outside temp is 37.5 and UV index is only 3 (out of a range of zero to ten) with ten being extreme uv intensity.

In other years at around this time and sun elevation I have seen readings at 7....So where has all of the uv gone??

The next reading will be with the sun directly overhead.

I can see that everybody is waiting in absolute awe for these observations. So while waiting , have a couple of

OK at mid day with sun near on directly overhead and clear sky and temp at 38 uv was 5. Still far from extreme but high enough to give you a burn if you stay out long enough.

HMMM. 14:30 a few brocken clouds about temp still 38 and a bit and uv is down to 3.5.
So where is all this extreme uv that Australia is supposed to be bathed in? It sure isn't over Canberra. Maybe it is all down South closer to the South Pole and all the big ozone holes.

My meter will read above 10 but I have never seen it go that high. 10 is rated as extreme and I sure would not go out side if the levels were that high.
    I agree that showering every day washes away all of the good stuff that protects our skin from attack by uv and bacteria and germs etc.
An interesting survey was carried out a long time ago  in the Uk/London on  homeless and other street people who almost never washed and it was discovered that a high majority had never been sick or had a cold or flu.
