Colombo in May
Not the best time
Monsoon season peaks with constant rain and flooding risks. Only visit if you're comfortable with major weather disruptions and have flexible plans.
Weather
May delivers the full southwest monsoon with daily heavy rains and oppressive humidity reaching 85%. Mornings might be clear but afternoons bring torrential downpours that can flood streets. The air feels thick and uncomfortable.

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.
