Does anyone consider certain temps "too hot to tan," as in,
the extra heat from the sun becomes undesirable or dangerous?

I'm figuring people from Phoenix will probably have an emphatic "yes!"

At 1 pm today:

- clear skies
- 82 F (28 C) with 48% humidity
- light winds where I was

Lying down in the sun, I soon heated up and started to sweat,
as if I were standing up in t-shirt and shorts on a day at 92-94 F. (33-34 C)

I don't know if it would ever be "too hot to tan" in Toronto,
but I suspect with similar conditions and 90+ F (32+ C) temps,
I will NEED a cold drink while tanning,
as I could assume it will feel like 100-102 F (38-39 C) at "only" 90 F.

I might even prefer to avoid tanning once it hits 95 F. (35 C)
Hopefully we will reach that this year and I'll get to find out.

I can imagine if it was 98+ F (37+ C) and someone was lying in the sun,
they'd get a lot of stares from shocked on-lookers.

Here in Vancouver, it could never be too hot to tan... the UV index at the best of times is pitiful as it is. I don't think I've ever seen the UV index hit 10 here ever. Highest was 8 or 9 I think.

UV-wise, 6 is a decent level for tanning, imho.
That's like Bahamas latitude in January.

Don't feel bad,
most of the Caribbean has UV of 7-8 in January.
Plenty of DARK caucasians there in winter, lol.

But my thread is about the effects of sun-heating, not UV.
On Mount Everest you could probably get a severe-sunburn and frostbite at the same time.

From mid-May to October 1st, it's too hot to tan here. Well, you can get a tan easily just walking to and from your car or doing a few errands. But, with Arizona being the number one state (I think anyways) for skin cancers, probably better to stay inside. And, they've measured Vit D blood levels from Arizonians and found that they're not much higher than people from other states (interestingly enough--I think it's hard to absorb enough D from the sun to raise the levels up enough), so another reason to stay indoors, while popping your Vit D.

I learned that vitamin D isn't produced without exposure to UVB.
UVB doesn't reach our skin unless the UV level is 4 or higher.
Glass like in cars block UVB, but UVA still gets through.

So,
it'd be easy for their vitamin D to be low if they avoid times of day where the sun is UV of 4
which in Phoenix is probably anytime your shadow is more than 50% longer than your height,
or they get most of their sun behind glass, which would be UVA.

Is there a particular temperature that is considered too hot to tan in Phoeniz?

Thanks for your reply btw.

^^ They probably meant "heat index of" 110 F.

110 F/43 C with 100% humidity would be a new record for Earth!
My guess is that could make a heat index of 200 F/ 95 C.

Here's the stats for Phoenix:
Average Weather for Phoenix, AZ - Temperature and Precipitation

So about 95 F is when most people in Arizona find it too hot to tan?

You don't see a lot of sun worshippers, except tourists, in the summer months maybe lying by the pool? (late May to early October). In the winter months, you see a lot of tourists sunbathing at their motels/resorts and being outdoors, in general. The months above are all over 100, and too hot to do anything much outdoors.
