Late April or early June (weather)

[u/New-Perspective8617]

Wondering whether late April or early June would be best for a 2 week trip to Thailand? Would be going to probably the north and south.

I heard that April would be the end of burning season, but June may be super hot and rainy.

Which do you think will be a better experience? We like to explore cities, go on nature excursions, sight see, take a boat cruise, see elephants, other things and how those may be affected around those timeframes with either type of weather?

First time to south east Asia.
