Key takeaways
- Thailand's rainy season runs roughly from May/June to October.
- UV is still strong on cloudy days — keep wearing sunscreen.
- Extra humidity can mean more breakouts and frizz; go lighter, not heavier.
- Water-resistant formulas and quick-drying textures make life easier.
Thailand has three broad seasons: hot (roughly March to May), rainy (roughly May or June to October) and cool (roughly November to February). The rainy season brings dramatic afternoon downpours, flooded sois, even higher humidity — and a lot of questions about whether your routine should change.
The short answer: a little, not a lot. Here's what to adjust.
Keep wearing sunscreen
This is the big one. Clouds reduce UV much less than people think, and Thailand's UV index can be high even on grey days. Between storms, the sun often comes out strongly. Keep your sunscreen habit — choose a water-resistant formula if you're often caught in the rain or sweating.
Go lighter, not heavier
With humidity at its peak, rich creams can feel suffocating and may contribute to clogged pores. Switch to gel textures, layer a hydrating toner instead of a heavy cream, and save richer products for the air-con at night.
Keep breakouts in check
- Cleanse thoroughly at night — double cleansing removes sunscreen and sweat.
- Change damp clothes and masks quickly; trapped moisture irritates skin.
- Use BHA a few times a week if you're oily and prone to clogged pores.
- Wash makeup puffs and pillowcases more often — damp, warm conditions are kind to bacteria.
Care for feet and body
Wet shoes and flooded streets are hard on feet. Dry them thoroughly, especially between the toes, and moisturise heels at night. A gentle body wash and quick-absorbing lotion keep skin comfortable without stickiness.
Frizz season
If your hair frizzes in normal Bangkok weather, the rainy season takes it up a notch. Lean on a leave-in and a light oil to seal the cuticle, and keep an umbrella and a claw clip handy. Our frizz guide has the full routine.
Makeup that survives a downpour
- Waterproof or tubing mascara.
- Lip tints instead of glosses.
- A setting spray to lock base in place.
- Blotting papers for after you've dried off.
What you don't need to change
- Your basic cleanse–hydrate–protect structure.
- Your serum, if it's working.
- Your sunscreen habit.
