At São Paulo, it should be usual to have days where the maximum temperature is around 15°C, but most should reach high 20's. It should rain a lot of the time too, but with a small amount of water.

But hot and dry days are not unheard of, they are just unusual.

I'm sorry you guys are experiencing this. I hope that my question isn't foolish, but is it possible that the deforestation in the Amazon is partially causing the reduced rain?

[marcosdumay]

I don't think so.

First, the forest covering of the Amazon didn't change that much on the last few years. Don't let international press fool you, the forest isn't "all burning down". It's burning down a lot, but not that much.

But more importantly, the rain on that region is mostly from oceanic and local humidity (São Paulo is in a forest area, with plenty of rivers).

It rains less there in La Niña years. I don't know how abnormal the situation really is. But the heat is way more unusual than low humidity.
