Kota Kinabalu weather by month

February really is Kota Kinabalu's driest month — the record confirms the forum's claim exactly, at 18 rain-days against 28 or more in November and December. What it does not mean is dry: eighteen wet days is most of the month, arriving as heavy short downpours and the odd thunderstorm with plenty of sunshine in between, and posters describe forty-five minutes of rain, then sun, then rain again. Temperatures barely move — 28 to 32°C by day and rarely below 24 at night, with the sea at 29. Mid-December to February is peak travel season in Sabah.

Forum posters describe August as capable of being genuinely rainy in Kota Kinabalu, with the wetter pattern sometimes spilling into September, though posters note short afternoon showers actually provide welcome relief from what would otherwise be an uncomfortably hot afternoon. Posters describe the typical daily rhythm as hot, dry mornings, clouds building around midday, a burst of rain for 30-60 minutes in early afternoon, then clear skies again in time for sunset - with rain often spotty enough that one part of the coast stays dry while a visible storm passes over the sea nearby. Posters flag July and August as peak season for visitors from Northern Asia, meaning bigger crowds despite the wetter weather. Posters generally rate August as hot, humid and rain-prone but rarely disruptive for Kota Kinabalu, the predictable afternoon shower pattern easy to plan around.
