Peak Season (Cool & Dry): November to February
If you’re looking for the best time to visit Thailand, most travelers recommend the cool and dry season between November and February.
Weather: 75–85°F, minimal rainfall
Where to go: Bangkok, Chiang Mai, Phuket, Krabi
Events: Loi Krathong (Festival of Lights), Chinese New Year (January/February)
Connectivity tip: Tourist traffic during peak season can lead to overcrowded Wi-Fi in hostels and public spaces. With ZIM’s eSIM, you skip unreliable networks and stay connected with fast, local data—ideal for Google Maps, Grab rides, and restaurant reservations.
Shoulder Season: March to May
Expect rising temperatures and fewer crowds. If you’re comfortable with heat, this can be a rewarding time to travel.
Weather: 85–100°F, dry and hot
Where to go: Mountain areas like Chiang Mai and Pai for cooler evenings
Events: Songkran (Thai New Year) in mid-April — a nationwide water fight and cultural celebration
ZIM traveler insight: Songkran is chaotic, fun, and unpredictable. Having mobile data means you can coordinate meetups, find festival tips, and capture moments in real time—even while soaking wet (just waterproof your phone).
Low Season (Green Season): May to October
Also known as the monsoon season, this time sees fewer visitors, lower prices, and surprisingly lush scenery.
Weather: Rainy, especially from July–September
Where to go: Koh Samui and Gulf islands get less rain than the west coast
