Everything You Need to Know About Bangkok in March

March signals the start of Bangkok’s heat, with temperatures climbing to 25–35°C and sunrise at 06:18. Mango season begins, and the city hosts Makha Bucha Day with candlelit temple processions. The Bangkok International Book Fair and Thailand Tourism Festival at QSNCC draw big local crowds. Early mornings are best for sightseeing, while afternoons call for air-conditioned escapes. Crowds thin slightly after February, but major events keep the city lively. Mango sticky rice appears everywhere, and night markets stay busy into the evening.

• Book hotels near QSNCC early if attending the Book Fair or Tourism Festival, as rooms fill quickly during these events.
• Go early to temples on Makha Bucha Day (3 March) for candlelit processions and to avoid midday heat—dress code strictly enforced.
• Reserve tables at popular mango sticky rice spots like Mae Varee, as queues spike with the start of mango season.
• Choose BTS/MRT for festival travel, as traffic around QSNCC and major temples is especially heavy during event days.
• Avoid outdoor sightseeing between 12:00–15:00—schedule museum visits or café breaks during the hottest hours.
• Head to Chatuchak Market in the morning for shopping and to sample seasonal fruit before crowds build.
• Book Thailand Tourism Festival workshops and food tastings online to secure spots and skip lines.
• Skip riverside walks in the afternoon and opt for evening cruises when temperatures are more comfortable.
