March weather forecast
Thailand

March heralds the commencement of summer in Thailand, marking a perceptible change in the weather landscape. The temperature across the country escalates, bringing warmer days and introducing a more pronounced heat in various regions.

The northern areas, adjacent to Myanmar and Laos, although having a more temperate climate in the previous months, now experience a shift with temperatures climbing noticeably. The coolness of the nights starts to wane, and the days grow hotter, especially towards the latter half of the month.

In Bangkok and the surrounding territories, daytime temperatures escalate further, frequently ranging from 32°C (89.6°F) to 36°C (96.8°F). The increased heat, combined with the city's inherent hustle and bustle, can make the urban environment feel even warmer, especially during midday.

Rain remains a rarity in March, maintaining the pattern of the preceding dry months. While the eastern coast close to the Gulf of Thailand can still expect occasional light showers, the majority of the country stays arid. The clear skies and abundant sunshine dominate the weather narrative of the month, although this means a stronger sun and higher UV levels during peak hours.

In comparison to February, March underscores the shift from the temperate conditions of winter towards the intense heat of summer. It serves as a precursor to April, traditionally one of the hottest months in the Thai calendar. As March draws to a close, one can anticipate even warmer days on the horizon, leading to the peak of the summer season.
