Your February weather guide
Yes, February is a good month for Thailand if you want hot days and relatively little rain. Country averages sit at 31°C by day and 24°C at night, with 5 rainy days, so plan for warmth rather than a break from the heat. Chiang Mai suits travellers who prefer cooler evenings, while Phuket offers a useful balance of beach weather and fewer rainy days than the other coastal destinations listed. The catch is that nights stay warm by the sea.

The sea averages 28.4°C around Thailand in February - warmest at Khao Lak (28.7°C). That is comfortable for swimming.
Around 6.5 hours of sunshine a day on average, out of 11.6 hours of daylight (sunshine estimated from cloud cover).

Based on the averages: light, loose clothing and serious sun protection - midday highs sit around 31°C; a light waterproof for the odd shower; swimwear - the sea is 28°C.
Within 1.5°C of Thailand's February daytime average: Goa (32°C, sea 28°C), Mombasa (32°C, sea 28°C), Guanacaste (31°C, sea 27°C), Rio de Janeiro (31°C, sea 26°C), Kerala (31°C, sea 29°C). See the full ranking for February.
Bangkok is the hottest choice, with average daytime temperatures of 32°C and nights at 24°C. Its 3 rainy days make February a sensible option if rain is your main concern, but the heat still calls for lighter plans around midday. Loose clothing and breaks out of the sun will be more useful than warm layers. Chiang Mai has a different balance: days average 31°C, but nights fall to 18°C, making evenings more comfortable if you dislike persistent warmth. With just 1 rainy day, it is also the driest destination listed. Choose Chiang Mai for hot days with a cooler finish, or Bangkok if warm evenings do not bother you.
Phuket combines daytime temperatures of 29°C with 4 rainy days and a sea temperature of 29°C, making it a good fit if you want warm swimming water without the highest daytime heat. Koh Samui is slightly cooler by day at 28°C, though its 6 rainy days suggest allowing more flexibility for wet weather. Both stay at 26°C overnight, so neither offers much cooling after sunset. Krabi reaches 32°C by day, while Khao Lak averages 31°C; their seas are equally warm at 29°C. The catch is rain: Krabi has 7 rainy days and Khao Lak 8. They still suit a warm-weather holiday, but Phuket is the stronger choice if fewer rainy days matter more to you than hotter afternoons.
A little more detail
Plain answers, grounded in the averages.
Bangkok is the warmest of the 6 places we track in Thailand in February with an average high of 32.3°C; Koh Samui is the coolest at 28.2°C.
The sea averages 22°C or more at Bangkok (28°C), Krabi (29°C), Khao Lak (29°C), Phuket (29°C), Koh Samui (28°C) in February.
Yes, sea temperatures are comfortably warm: 29°C around Phuket, Krabi and Khao Lak, and 28°C around Koh Samui. Temperature should not be the main obstacle to a swim, though warm water alone does not tell you about conditions on the day.
Pack light, loose clothing, sun protection and something light for rain. A light layer is useful for Chiang Mai evenings, where nights average 18°C. Coastal nights are much warmer, so prioritise breathable sleepwear rather than heavy evening clothes.
Thailand averages 6.5 hours of sunshine a day in February. That supports outdoor plans, but it does not mean uninterrupted clear skies. With daytime temperatures averaging 31°C, leave room for shade and a slower pace around midday.
