February rivals January as Thailand’s best month overall. Dry season continues across both coastlines, temperatures are warm without the brutal heat that arrives in March and April, and sea conditions remain excellent for diving and island hopping. The one downside: burning season begins in the north.
Weather by Region
Bangkok is warm and dry at 29-33°C with very little rain. Humidity is low by Bangkok standards, making this one of the most comfortable months for walking tours of the Grand Palace, Wat Pho, and the canal neighbourhoods. Evenings are pleasant for rooftop bars and night markets.
Chiang Mai and the north remain dry but burning season begins in February. Agricultural and forest burning creates a haze that worsens through March and into April. Air quality can deteriorate significantly, particularly in valleys where smoke is trapped. If you have respiratory sensitivities, consider visiting Chiang Mai in November-January instead.
Andaman Coast (Phuket, Krabi, Koh Phi Phi, Koh Lanta) is at peak conditions. The Similan Islands are open with superb visibility for liveaboard diving. February is considered the single best month for Similan diving - water temperature sits at 28-29°C with 25-30 metre visibility. Koh Lipe in the far south is accessible by ferry and at its most pristine.
Gulf Coast (Koh Samui, Koh Phangan, Koh Tao) continues in peak season. Calm seas, warm water, and consistent sunshine. Koh Tao remains one of the world’s most affordable places to earn a PADI Open Water certification, and February offers the best conditions for it.
Festivals and Events
Chinese New Year (late January or February, date varies by lunar calendar) transforms Bangkok’s Yaowarat Chinatown into a sea of red lanterns, dragon dances, and street food stalls. The celebrations span several days and are among the largest outside of China. Phuket’s old town hosts equally significant events given the island’s Hokkien heritage. Book accommodation in advance if your trip overlaps with the new year weekend, as Bangkok’s Chinatown hotels fill quickly.
The Chiang Mai Flower Festival takes place in early February with flower-decorated floats parading through the old city, beauty pageants, and garden displays at Suan Buak Haad park. It is a genuinely local event, not a tourist production.
The Full Moon Party on Koh Phangan runs monthly year-round. February’s edition benefits from excellent weather and calm seas - the party itself runs through the night at Hat Rin beach. See the Full Moon Party guide for what to bring, safety advice, and alternative beaches for those wanting to be on the island without the noise.
Diving Season
February is arguably the best diving month in Thailand. The Similan Islands and Surin Islands are at peak conditions. Whale shark sightings at Chumphon Pinnacle (near Koh Tao) increase from February through April. Richelieu Rock, regularly ranked among the world’s top dive sites, has optimal visibility.
Prices and Crowds
Still high season pricing across the country. February half-term holidays from Europe and school breaks from Australia add to demand. Beach resort prices remain at peak levels. Booking 4-8 weeks ahead is advisable for Phuket and Koh Samui. Bangkok hotels offer better value as the city has enormous capacity.
Which Islands to Choose in February
February is perhaps the easiest decision of any month — every coast is good. The question is atmosphere.
Andaman Coast: Phuket is in its prime, with Similan Islands liveaboards fully operational and the best visibility of the season. Koh Phi Phi is busy but justifiably so — the turquoise water and limestone karsts are at their most dramatic under February’s clear blue skies. Koh Lipe in the far south is worth the longer journey for its smaller scale and better snorkelling than Phi Phi. Koh Lanta suits travellers who want beach and yoga without nightlife.
Gulf Coast: Koh Samui is excellent — the island’s reverse monsoon means it is reliably dry February through April. Koh Tao is the world’s most affordable place to earn a PADI Open Water certification, and February conditions are among the best of the year for it. Koh Phangan offers the Full Moon Party as well as quieter northern and western bays away from Hat Rin.
The north — but be aware of burning season. February is the last comfortable month in Chiang Mai before air quality deteriorates significantly. If combining beach and mountains, visit Chiang Mai first (or early February) and head south for the coast in the second week. Koh Chang on the eastern Gulf is at peak condition in February and considerably less visited than Samui — a good alternative if crowds are a priority concern.

Accommodation Prices in February
February pricing mirrors January at most beach resorts. Phuket beachfront hotels run from approximately 3,500–12,000 THB per night; mid-range options in Patong or Kata start around 1,200–2,500 THB. Koh Samui resorts average 2,500–6,000 THB for a decent sea-view room. Bangkok is better value - expect 1,200–2,500 THB for a 3-star, 4,000–8,000 THB for a 4-star in central neighbourhoods. Valentine’s Day week (around 14 February) sees premiums at romantic resorts - book well ahead if you are travelling for a special occasion.
What to Pack
Light summer clothing throughout. Chiang Mai evenings can drop to 15°C - a light jacket is useful. For the coast: reef-safe sunscreen, a lightweight rash vest, and sandals you can wear in the water. Temple visits require covered shoulders and knees - a sarong or loose cotton trousers weighs almost nothing and avoids being turned away at the entrance.
Planning
See the best time to visit Thailand for a full seasonal comparison, or the Thailand budget guide for cost planning. Browse Thailand tours and activities - February is peak season for island day trips, Similan Islands liveaboards, and Chiang Mai experiences.
Plan Your Trip
February is the single best month for Similan Islands liveaboards — the clearest water and best manta ray and whale shark visibility of the season. Book liveaboard trips departing from Khao Lak 4–6 weeks ahead. If you’re combining Chiang Mai with a beach, schedule Chiang Mai in the first half of February before the burning season haze takes hold — by mid-month, air quality is already deteriorating. Chinese New Year (late Jan or Feb) inflates Bangkok Chinatown hotel rates for a few days; book ahead if your dates overlap.
