Low Season: Predicting The Weather
Low season is approaching fast. In Thailand it lasts from May till September. What will the weather be like in different regions of the country in the next five months?
The Eastern Seaboard: Pattaya
The record high in Pattaya normally observed in April (32,9oC); but as far as the year average here is quite stable, do not expect average high lower than 31oC. In May–June Pattaya lives through the ‘hot and humid’ season when rainy days can account up to one third of the whole month, and total rainfall is around 120-148 mm. The main monsoon comes in September–October, with rainy days reaching 17–18 (204-217 mm).
The North Chiang Mai
The North is not necessarily synonymous to ‘cold’. The April average high in Chiang Mai is two degrees higher than in Pattaya. The basic tendency in summer is similar to Pattaya: temperature is lower (from 34,7 oC in May to 31,7 oC in September), humidity is higher. Note that the highest precipitation (211-216 mm) and more rainy days (from 16 to 20 per month) fall between July and September.
The South: Phuket
Water, water all around – that is what the low season in Phuket about. It is not just because Phuket is an island; it means that the number of rainy days per month varies from 19 to 23, and precipitation is about 250 mm, reaching the record 360 mm in September. Do you still long to go to the south? The average temperature is about the same as everywhere else in the country: average low is 24-25 oC, average high is 32 oC.
Isan: Mukdahan and Nong Khai
Isan is a vast region, but for many Pattaya expats the two provinces are of major importance: Nong Khai (border crossing to Vientiane in Laos) and Mukdahan (Savannakhet). The average high in both cities are not comfortable from May to September, reaching 32-34 oC) with record 40-42 oC. August is the wettest month: 320 mm+. The other summer months are much rainier that the worst Pattaya’s September and October: from 220 mm.
