Pattaya weather in October

Regulars are direct this counts as the hottest month of Thailand's three seasons, midday temperatures regularly hitting 35-38C with one visitor's own account reaching over 40C poolside. Our row backs that brutally hot, humid read, 33.4C reading as a scorching 40C, over 27.1C nights, with 87.4mm of rain across 13.2 days and humidity at 76 percent. Regulars are consistent that when rain does arrive it's usually a brief but genuinely intense evening thunderstorm rather than an all-day soak. This month also hosts Songkran, Thai New Year, around April 19th, a real cultural highlight alongside the heat that draws its own crowds. The sea sits at a bath-warm 30.6C. The record: 10.8 hours of sun, a 13.6 kph wind and AQI 68.

November is a switch rather than a month here: the wet southwest monsoon hands over to the drier northeast one, and regulars put the change around the second week, after which the cool dry season runs through to February. Early November can still catch the back end of the rains, though the heavy showers do not last long. Our row is the whole month averaged across that changeover - 84.5mm across 12 days, front-loaded rather than spread evenly. The heat does not ease with it: 31.5C reads as 36C at 77.4 percent humidity, and the nights hold 25.4C. The sea is 29.6C, warmer than the night air. The record: 9.4 hours of sun and AQI 54.

Pattaya-forum threads on March weather describe the tail end of the cooler, drier peak season tipping over into the hot stretch that runs through April: February and March are usually the driest months, but posters note temperatures start climbing noticeably by mid-March, uncomfortable by the back half for some visitors. One trip report specifically called the weather good but too hot, with no rain and no cloud the entire stay. Regulars class March through April as genuinely hot, warmer than the November-through-February window most visitors picture when they think of Pattaya's best season. The record: 32.5C days feeling like a sticky 38C, 26.3C nights, 56mm across 11.7 days, a 28.7C sea, 77 percent humidity and 10.8 hours of sun.

February is one of the two months Pattaya regulars call the coolest, which here means daytime that may not exceed 30C and nights that only fall to about 25 - our row gives 31.5C and 24.9C, reading as 35C once the humidity is counted. It is also among the drier months, though not rainless: 39.5mm falls across 6.4 days, and the forum's own description keeps some daytime rain in it. The direction of travel is the useful part. February and March are the dry pair, but from about the middle of March the temperature starts climbing into genuinely uncomfortable territory and April is the hottest month of the year. November to February is when the visitors come, for exactly this reason. The record: 10.8 hours of sun, a 27.7C sea and AQI 84.
