Weather in Kandy in May
Sri Lanka · 20-year averages, May
Shoulder season. May is shoulder season in Kandy — cheaper, quieter, and a genuine gamble. You should expect rain on 18 days of the month, which is more days wet than dry.
May ranks 11 of 12 — near the bottom of Kandy's year. February is the month that works, and the swing between the two is 24 points, which is a different holiday rather than a slightly better one.
Rain on 18 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Natural fibres and a second shirt for the day. At 83% nothing dries, including you.
What the averages hide
Averages flatten a month, and this one hides a few things: 8 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest May day reached 35.6 °C and the coldest night fell to 19.1 °C, and the wettest single day dropped 155 mm — roughly 117% of the month's rain in one day.
May is moderately variable: 17 mm in the driest year against 417 mm in the wettest, around an average of 133 mm. Roughly two Mays in three land near that average, and the third does something else entirely.
Wind is light at 11.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, high enough to notice on the warm days without dominating them.
How May sits in the year
Temperatures hold steady either side: 30.8 °C in April, 29.1 here, 28 in June. Nothing about the timing within the month matters much.
Daylight in May
Kandy sits close enough to the equator that daylight barely moves all year — 12.4 hours in May, against a range of just 0.8 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.
An inland climate
Despite being inland, the year stays fairly even: 12.8 °C between the year's warmest afternoons and coldest nights.
How busy it gets
Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
May in Kandy versus nearby
If Kandy is one option among several, the nearby comparison is worth making. Colombo is close enough to be a coin toss — within a degree on temperature, 8 days more rain. Trincomalee is close enough to be a coin toss — 3.1 °C warmer, 7 days less rain.
So: May is a compromise. February is 19 points better and is what Kandy is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
