Your Complete Guide to Bangkok in May

May brings hot, humid days (26–37°C) and the first hints of monsoon. Sunrise is at 05:52. Durian and mangosteen flood the markets, and the Royal Ploughing Ceremony marks the start of rice season. Visakha Bucha Day (31 May) brings candlelit temple processions and an alcohol ban. Afternoon storms are possible, so pack an umbrella. Hotel rates drop, and crowds thin out after Songkran. Early mornings are best for sightseeing, while afternoons are for fruit markets or indoor escapes. May is a transitional month, with lush city parks and tropical flavors at their peak.

• Book hotels near Sanam Luang early if attending the Royal Ploughing Ceremony (11 May), as crowds gather before dawn.
• Go early to Or Tor Kor Market for the freshest durian and mangosteen—vendors sell out quickly during peak season.
• Reserve tables at popular fruit dessert cafés, as locals flock to try seasonal specialties in May.
• Choose indoor attractions or malls for afternoon plans, as sudden storms can disrupt outdoor sightseeing.
• Avoid outdoor activities during Visakha Bucha Day (31 May) afternoon, as many venues close early and alcohol sales are banned.
• Head to Lumpini Park at sunrise for cooler temperatures and active wildlife before the heat builds.
• Book airport transfers in advance during public holidays, as demand for taxis and Grab surges.
• Skip riverside walks during afternoon storms and plan for evening strolls when the air is cooler and rain has passed.
