Colombo in September
Not the best time
Transitional month with improving but still unpredictable weather. Budget-friendly but requires flexibility with outdoor plans.
Weather
September brings a brief dry spell called the 'inter-monsoon' period with mixed conditions. Humidity stays around 75% and while major rains decrease, you'll still get unpredictable showers. Mornings are often clear but afternoons remain uncertain.

All Months
December through March gives you the dry season with temperatures around 27-30°C. This is peak tourist season, so guesthouses charge more and Galle Face Green gets crowded with families.
July and August bring the southwest monsoon, but it's not the city-stopping rain you'd expect. Afternoon showers clear the air and cool things down. Hotel prices drop 30-40% and you'll have temples mostly to yourself.
Avoid April through June – it's hot, humid, and miserable. May hits 35°C with crushing humidity. September through November brings unpredictable weather, but also the best fruit season. Mangoes and rambutans are everywhere and cheap.
