Well in a word....... NO
It is always hot in Jakarta, 365 days a years.
Always over 32C degrees during the day
Yesterday it peaked at about 37C for about an hour....(nearly 100F)
Once it rained so heavily the temp dropped to 27 C for about 5 min..then it was back to stinking hot with the added bonus of high humidity.
Sometimes if you are lucky the temp will drop to about 24C at 3-4 am.
So weather in Jakarta is:-
- Wet season- hot and humid.
- Dry season- hot and dry.
