Weather in Bangkok in May
May in Bangkok is the hard heat. Outdoor plans belong to the ends of the day. The middle is for indoors or water.
In Thailand, this is how Bangkok actually wears May, not how a country centroid would. Compared with April and December, May sits in the middle of Bangkok's year.
