I heard that one day last week Chiang Mai was the hottest place on Earth! When the temperature starts approaching 40 degrees, it actually becomes painful. It's like someone is holding a damp towel over your face; it's hard to breathe. It's so hot that it makes my brain stop functioning, and I'll go for minutes on end without having a single thought.
Our car doesn't have a/c, so it can be quite uncomfortable to ride in there during the day. We have a small fan that I hold on my lap to try and get some air circulating, but all it really does it blow the hot air right in your face. William and Isabella leave sweat marks on their car seats when we get out. It doesn't matter how hot it gets, though, we still see Thais cruising around on their motorbikes in sweaters. The forecast for this week has the max temperature at 30 degrees, so who knows, maybe we'll get our sweaters out, too.
