What climate are humans naturally built for?

Hmm I'm thinking maybe Bermuda, La Palma or Cape Verde if we're going to be completely without clothing under current circumstances. Maybe Saint Helena too, when I think about it.

Avoiding heat strike is kind of important though, even in some of those climates.

Mediterranean and tropical highland.

I would say a climate a climate like Georgetown, Guyana (with less precipitation aided for savanna or open forest landscapes)

Or this - en.wikipedia.org/wiki/Dar_es_Salaam#Climate

Anything colder I think Humans will shiver or need the aid of clothing (which isn't natural)

Can Humans survive a couple days without water?

What about Norfolk Island?

Azores can get close to frost after all.

The difference between Humans and the great apes are many features that make Homo Sapiens more adapted to move in water - wading and swimming: The human nose that is completely different from the great apes and very well adapted to swimming forward, the lack of body hair, the long leg bones perfect for wading in coastal waters and rivers.
And think about it: Where is it easier for a human without modern technology to get food: The Savannah in competition with lions and Hyenas, or the coastal areas with their abundance of different type of sea food. Also, why is it that sea food is good for our health, while red meat is bad for our health?

There is enough fossil evidence to suggest that by 2 million years ago, our Homo ancestors were living and moving via the coasts through parts of Asia and Eurasia. Verhaegen believes that H. erectus was predominantly semi-aquatic, a frequent swimmer and efficient slow diver, and that wading may have come about later, as part of a move back to a more terrestrial existence, as a result of the cooling global temperatures...

The caves near the coast in south Africa /East Africa has proven more than 100,000 years of human habitation.
So we are built for a climate like....Durban

Note that much of Africa is actually at quite a high elevation. The climate of Kampala, for instance, looks like it would be very comfortable for prehistoric humans - no need for heating or AC.
