I thought it is just my place that is hot until I came across a certain post on a forum stating that it is 29 degree during 3am at night.

My place is around 29 degree at 3am. Ahhhh.

Using my Xiaomi temperature sensor, it shows that my current room is at 32 degree at 12 midnight.

As I am only staying in a rental flat for few months, I did not install a larger air con unit. I am currently using a portable aircon and it seemed that it is not very efficient in cooling the whole house.

The temperature after using the aircon for 2 hours, is still 29 to 30 degree. I have to use a mixture of fan and aircon in order to make my room cool enough to sleep.

Singapore is so hot indeed.
