Google questions like this first, this site is not a substitute for Google. South Central Thailand does not usually get the full effects of the southwest monsoon that is felt by most places further north in Thailand and in the south at the end of May, but Pattaya still gets its fair share of rain at this time of year. The rain tends to come in hour-long downpours. It is rare for it to rain all day or night, but some streets flood if there is heavy rainfall, and it can take an hour or so to clear. In Pattaya very few people brave the torrential rain, but just stay where they are, wherever they are, until it stops, which is only usually half an hour or so. Rain during June, July and August does tend to dampen down the heat for a bit, but half an hour later the humidity can be unpleasant. The temperatures tend to stay in the low 30s by day and night during the May/September rainy season with high humidity readings (90 per cent). Inland, away from the sea, mosquitoes can be a problem. I got all this on my first try. Please don't make other people do your homework for you.
