Although most of Thailand is designated as having a tropical climate, there is significant variation in the weather patterns of different regions in April. This is because Thailand is a large country. Of the 257 recognized nations in the world, Thailand has the 52nd largest area of land mass. That is, there are more than 250 countries with smaller land areas! Moreover, Thailand is approximately 1,650 kilometres in length from the northern-most point to the southern-most point, and the nation has a width of around 800 kilometres at the largest east to west vector. Bordering countries of Thailand are Laos and Myanmar to the north; Malaysia to the south; Cambodia, Laos and the Gulf of Thailand to the east; and Myanmar and the Andaman sea to the west. The differences occurring in the Thailand weather patterns are, in part, due to this large degree of geographical variation.
In consonance with the Thailand climate patterns and meteorological conditions, the country can be divided into 5 distinct areas: the north, north-east, central, east and southern regions. Some of the well-known cities and towns in these regions are, respectively, Chang Mai, Udon Thani, Bangkok, Rayong and Phuket. For most visitors to Thailand, the top temperature would be high enough in all regions throughout the year, to be felt as consistently hot, especially during the days. However, there are some regions, like Isaan and the northern districts where the temperature dips quite considerably at night. For examples, in the Isaan town of Loei, the night-time temperatures in December and January can get down to 10C, while in Chiang Mai the lowest temperature ever recorded was -5C in December, 2017!
April Thailand Weather
The Thailand weather in April, is of course, also determined by which part of the country is being considered. In Khao Lak, there is only a small variation in the average monthly temperatures. The average highest temperature is 32C from July to January, 33C in May and June, and 34C from February to April. Thus, April is the equal hottest month of the year with February and March, although with such small variations between the months (2C) it is hardly noticeable. The same is true for the lowest average temperatures which range from 23C to 25C. But what really does make a difference are the average monthly rainfalls. December to March has the lowest average rainfalls, May to November has the highest, whereas April is in-between the two. That being said, for most years Khao Lak does have storms during April. However, the average number of days with rain is 14 (compared to 23 days in September and October).
The Khao Lak weather conditions in April are conducive to enjoying what the region has to offer. For example, The Thai New-Year festival of “Songkran” is always celebrated in the middle of April, and there is always a large fun-filled turnout. April is a good time to visit Khao Lak, and Songkran is not to be missed.
