The hot in the sun comment is a typical situation in NZ. The temp here today is 21C (70F) but the UV for today is 14. I saw some serious Lobsters in town today!
I'm amazed at how high your UV indexes can get for the southern hemisphere. At around a similar latitude (low 40s N) in Toronto, and southern Ontario in Canada, it seems like it rarely gets higher than 9 (at least from my experience).

I saw a UV forecast of 10 once or twice last summer here, btw.
Two reasons for higher UV:
-southern hemisphere is closer to the sun in their summer
-southern hemisphere has cleaner air because most of it is water, less people live there, lower chance of volcano eruption or forest fire
Looking in the column furthest to the right,
both show that Toronto and Auckland are about 3% closer to the sun in December vs. June.
(152 x 10-to-the-6th kilometers vs 147 x 10-to-the-6th kilometers )
I wonder how much worse Canadian winters would be if those distances were reversed.
A few months ago I thought I read an article that said Carnarvon, WA had Australia's highest ever recorded UV reading of 17.
Honestly, I didn't expect to see a UV of 18 anywhere in the world less than 1500 metres/5000 ft above sea level.
"The highest UV index level in Canada to date, was 10.1. This was recorded in Toronto on
July 07, 1993."
Hmm... I don't know how intuitive that feels. I would have expected something higher.
Mt Everest wouldn't be too kind either.
Chile looks ridiculous; on a colour map of UV in December it was white (off the charts) where Australia was pink in its worst parts.
I wonder if The Weather Network was being cautious.
We had a clear day in late June or very early July that I saw a day at UV of 10.
The way UV feels to my skin, it's almost linear with intensity.
4 feels about half the strength of 8.
10 felt like a subtle but noticeable increase over 8.

One certainly has to be cautious, but by the end of april it's comfortable in the sun most of the time. Just remember to "slip, slop, slap".

What's your UV in midwinter? I don't really take much notice but I think ours is 1 from roughly October to March, going up to 6 or 7 in midsummer. By late October in this country even in the south you could spend all day in the sun and not get any colour at all. From about then until mid-March I don't properly expect to even see the sun never mind feel any strength in it. It wasn't until I did a bit of travelling and talking to foreigners that I realised how bad for sunshine our climate really is.
My UV index is 1 right now and it's a bright sunny day. I'm near NYC right now. It probably stays 1 for a shorter time than October to March, perhaps a month less? Highest it generally gets in midsummer is 9, though I think 10 or 11 can happen in June.
