As we have been experiencing, the heavy rain is forecast to last until around May 25.

The Thai Meteorological Department has forecast the onset of the rainy season, with continuous rainfall expected from May 13-17 and May 18-22, 2025, driven by a strengthening southwest monsoon. The department warns of widespread rain, with 70-80% of Central, Eastern Thailand, and Bangkok affected, while the South faces risks of flash flooding.

quite wet rainy season indeed

It has arrived earlier than usual. And the amount of rain has been considerably greater than usual. Normally you could expect an hour or so fo rain followed by some nice sunny weather. Two days ago Bangkok had five hours of continuous rain.

daytime or evening / night ?

Two days ago it started around 5:00 am with the loudest crack of thunder which woke me up. Today it started about an hour ago (10:50 am) and it remains very gray outside with rain lashing down.

Usually early morning then happy hour time. Only about 45 minutes at a time.
Can vary (before another disagrees with me). 

I have some time off late June to early July but the thought of rain turned me off...the last time I was in BKK during the rainy season, the road in front of my hotel (quarter silom) was like a river 😅

I was in Bangkok in all months other than March and April and can't say even rainy season derailed  even any plans as usual gathering clouds indicate what is  going to happen and there's time to look for shelter.

Yes , soi 6 is prone to flooding and drains quite slowly but that shouldn't stop anybody from having fun on upper floors.

or doing their laundry in the rain....

Statistics for the period May 1 - 14 show that rainfall was 95% greater this year compared to the 30-year average. In a Bangkok Post article much of the rain during the month fell in what it calls "rain bombs". These were caused by a stronger southwest monsoon in the Gulf of Thailand coupled with a stronger monsoon covering the north of the country and part of the south. Then between May 25 and 27 the deluge of rain was reminiscent of the severe flooding of 2011. All this is odd because May is not generally a month for heavy rain.

Associate Professor Seree Supratid, director of the Center for Climate Change and Disasters at Rangsit University, has said that the weather phenomenon La Nina has altered its usual pattern this year with climate instability and unpredictable seasonal shifts. However, he suggests that  rainfall will ease this month and next, with August and September seeing drier weather. The rains will then return in October as usual.
