Погода: Самуй, ноябрь

Regulars are consistent this month runs genuinely dry and hot overall, sunshine the default, with only occasional midday-to-afternoon thunder showers rather than a settled wet stretch - some recent Aprils reportedly saw no rain at all for the entire month. Our row backs that brutally hot, humid read, 31.8C reading as a scorching 39C, over 26.4C nights, with 117.7mm of rain across 11.5 days and humidity at 78 percent. Regulars are consistent this counts as a genuinely great time to visit overall despite the intense heat, water and shade breaks the standard advice for anyone spending real time outdoors at midday. The sea sits at a bath-warm 31.5C. The record: 10.6 hours of sun, a 19.3 kph wind and AQI 49.

Regulars are specific that this island sits on the opposite monsoon cycle from Thailand's west coast - Samui is in its drier season this month while Phuket and Krabi are deep in their wet one, with Phuket averaging roughly 260mm of rain in August against Samui's much lighter total. Our row backs the milder wet read, 76.9mm across a real 17.5 days, alongside intense heat, 33C reading as a hot 38C at 76.6 percent humidity, over 25.7C nights. Regulars describe the typical shower as brief, often a 5-20 minute early-evening burst rather than a day-ruining event, with the sea staying calm and glassy for water activities most of the month regardless. The sea holds a warm 30.2C. The record: 9.6 hours of sun, a 23.5 kph wind and one of the cleanest air readings in this project, AQI 27.

Koh Samui-forum threads on June weather describe a reliable, easy pattern: sunny mornings, building cloud through the afternoon, and an occasional shower that posters call a genuine blessing rather than a disruption, since it cools things down without stopping swimming or beach time. All-day, non-stop rain is described as rare rather than typical. June and July together sit inside the island's low-rain season on the Gulf coast, seas calm and generally good for boat trips. Regulars note it runs warmer than the cooler stretch of the year, though most call it manageable, April and May singled out as the actually punishing months. Crowds are consistently described as noticeably thinner than the December-to-March peak season, a real upside for anyone prioritizing quieter beaches over a guaranteed clear forecast. The record: 33.4C days feeling like a punishing 38C, 25.6C nights, 75mm across 17.1 days, 76 percent humidity, a 30.6C sea and 9.6 hours of sun.

January on Samui is the turn out of the island's wet season - which here runs roughly October to the end of December, out of step with most of Thailand - into the cool dry stretch that lasts to March. Being the tail end, it is variable: regulars describe hits and misses with plenty of sun between them, and say the bad weather is usually a short heavy shower followed by sunshine rather than anything prolonged. Our row's 100mm across 9.8 days is that pattern. The part worth planning for is the sea, which can be rough in January, particularly on the east coast, making swimming awkward unless you are on a protected beach - Choeng Mon is the one they name. It is also less humid than later in the year. The record: 29C days that feel like 33C, 24.6C nights and a 28C sea.
