There are 4 climates that one tends to encounter in Singapore
1. Hot and humid
2. Hot and rainy
3. Airconditioned + wet from being sweaty
4. Airconditioned + wet from being drenched from rain
The former 2 being predominantly macro climates while the second 2, micro ones depending on an individual's lifestyle.
Today it was a cross between 1. and 3. as I trudged to the train station in jeans, well aware that the air conditioning in my destination would get to me otherwise.
Fortunately, I've since learned that emitting sweat up to a certain level does not lead to a stink, after it dries, as I restrained my pace to maintain a low sweat emission. One does not want to be too offensive in a train packed with passengers even at 8:35am on a Sunday.
