The short answer: December to April is glorious. The long answer is that Ban Krut is quietly lovely for most of the year.
Find a room before you go.
Ban Krut sits on the Gulf of Thailand, and the Gulf runs on a different monsoon clock from the Andaman side. While Phuket is drenched from May to October, Ban Krut stays largely dry — its wet season is short and late, concentrated in October and November when the north-east monsoon arrives.
That makes the quiet coast a genuinely good shoulder-season choice: European summer holidays land in perfectly decent beach weather here, and the classic high season from December onward is dry, breezy and never crowded — because Ban Krut never is.

These are the postcard months: day after day of sun, sea breezes taking the edge off the heat, and calm swimming water. Thai weekenders arrive around holidays and the resorts along the beach road fill on Fridays — by local standards, that counts as busy.
March and April turn properly hot, with afternoons above 33°C. The sea is bathwater and the sunrises are at their most reliable — bring a hat for the bike rides.

May to September is the in-between: hot, mostly dry, with occasional dramatic evening thunderstorms that clear as fast as they come. The coast is green, the fruit stalls overflow, and you'll often have the whole beach to yourself.
October and November bring the real rain — sometimes days of it — and the sea can turn choppy. It's the coast's quietest, moodiest stretch: fine for temple trips and massage days, less fine for snorkelling plans.

The real rain falls in October and November, when the north-east monsoon reaches the Gulf coast. The rest of the year sees only short, mostly evening showers.
Yes — unlike Thailand's west coast, the Gulf side stays largely dry in the European summer. Expect hot days, green scenery, brief evening storms and a nearly empty beach.
From roughly January to September the Gulf here is calm and swimmable. October to December can bring wind and chop along with the rains.
Thai weekenders and families arrive around public holidays, long weekends, Songkran (April) and New Year — book beachfront rooms ahead for those dates.
