Bangkok Weather Seasons
Bangkok’s weather plays out in three acts—each with its own flavor. Here’s the scoop, with temps and tricks to stay sane:
Hot Season – March to May
It’s a furnace out there—35-40°C (95-104°F) with humidity that clings like a wet towel. Days are dry and brutal, ideal for air-con havens like Siam Paragon. Nights hover at 28°C (82°F)—sleep with a fan or suffer. Light tees and hydration are your lifelines.
Rainy Season – June to October
Monsoons roll in hard—200-300mm of rain a month. Temps sit at 30-34°C (86-93°F), but the 90% humidity’s the real kicker. Afternoon floods are common; mornings might fake you out with sunshine. Ponchos and patience are key.
Cool Season – November to February
The sweet spot—25-32°C (77-90°F) with humidity dropping to 60%. Nights cool to 20°C (68°F), so you might actually use that jacket. Dry and breezy, it’s tourist heaven—plan ahead or get squished in the crowds.
Weather Highlights by Month
April – Heat Central
Peak hot season—37°C (99°F) highs. Songkran’s water fights offer relief, but otherwise, it’s a sweat-fest. Indoor escapes are your best bet.
September – Rain Overload
Wettest month—up to 340mm of rain. Streets flood, traffic stalls—stick to BTS or MRT. Umbrellas aren’t optional.
December – Cool Calm
The chillest time—25-30°C (77-86°F). Dry skies and mild nights make it perfect for rooftop cocktails or park picnics.
Tips for Bangkok Weather
Check Thai weather apps like TMD daily—rain can sneak up fast.
Wear breathable gear—cotton beats denim in this humidity.
Pack an umbrella always—sun protection in hot months, rain shield in wet.
Have indoor plans ready—malls or museums beat a soggy day.
Dodge midday heat (11 AM-3 PM) in hot season—early or late is cooler.
Roll with it—wet shoes or a sweaty back are just Bangkok’s welcome hug.
