When to Visit Satun

Daytime temperatures reach around 31°C (87°F), dropping to a comfortable 21°C (69°F) at night, the coolest lows of the dry season. Rainfall is low at around 51 millimetres for the month. The sun tends to dominate.

Temperatures rise slightly to a high of 33°C (91°F) with lows around 23°C (73°F), and rainfall holds at the same modest 51 millimetres. The days feel clear and manageable. The islands are accessible and at their most photogenic.

The warm edge of the dry season, highs push up to 34°C (93°F), lows sit at 24°C (75°F), and rainfall stays at 51 millimetres. The heat is noticeable but not oppressive. Shade and a cold drink sort out most afternoons.

The first signs of the wet season appear, with rainfall jumping to around 188 millimetres and afternoon storms becoming more frequent. Temperatures peak at 35°C (95°F) with lows of 25°C (77°F). The combination of heat and building humidity is the most demanding of the year.

Rainfall eases slightly to around 145 millimetres. But the wet-season pattern is now established. Expect rain most days, often in extended afternoon episodes. Highs stay at 35°C (95°F) and nights are warm at 25°C (77°F).

Interestingly, June behaves more like January than you would expect from a month sitting squarely in monsoon season. Rainfall drops back to 51 millimetres, making it one of the drier months of the year. Highs remain at 35°C (95°F) with lows of 25°C (77°F). For those willing to take a chance, the islands can be in fine shape at this time.

The dry interlude continues, with rainfall again around 51 millimetres and temperatures easing slightly to a high of 34°C (93°F) and lows of 23°C (73°F). This is probably Satun's most underrated month. Settled enough for island trips. Far fewer visitors than the December-to-March window. The national park at its most peaceful.

The second wet period arrives in earnest. Rainfall climbs to around 277 millimetres and downpours become heavier and more sustained. Temperatures reach 35°C (95°F) with lows of 23°C (73°F). The combination of heat and rain makes for sticky, unpredictable days.

Rain continues, with around 211 millimetres falling across the month. Highs ease slightly to 33°C (91°F) and lows hold at 23°C (73°F). Ferry schedules to the outer islands grow unreliable. The sensible move is to plan Satun town and mainland activities during this stretch.

Rainfall climbs again to around 262 millimetres, and the skies above Satun can stay grey for days at a stretch. Temperatures reach 34°C (95°F) with lows of 24°C (75°F). While the rain tends to fall in concentrated bursts rather than all-day drizzle, outdoor plans need real flexibility.

November is Satun's wettest month by a significant margin. Rainfall typically reaches around 638 millimetres. The northeast monsoon pushes sustained, sometimes multi-day rain events through the province. It is also the coolest month. Highs reach only 25°C (77°F). Lows sit around 20°C (68°F). Island ferries cancel regularly. Most travellers sensibly skip November entirely. Use it for inland and town exploration if already in the area.

The worst rain begins to ease in December. The month still delivers around 213 millimetres. That is more than enough to disrupt plans early on. Temperatures recover to a high of 31°C (87°F). Lows hit 21°C (69°F). Clearer days return as the month progresses. The dry season reasserts itself. Late December becomes a reasonable time to arrive.
