Is August a good time to visit Phuket?
Our Phuket guide recommends: November to April, the dry season — the rainy season from May to October can bring rough seas and reduced boat trips.
If visiting outside the dry season, check sea conditions before booking island-hopping boat trips — some routes reduce or pause in rough weather.
