Weather in Kota Kinabalu in March

A hard month. March asks something of you. Go in knowing what. The heat itself is manageable at 30.8 °C, but 85% humidity is what you will actually feel.

Kota Kinabalu barely has seasons. March scores 49 out of 100 against a best of 59 in February — a gap small enough that the month you choose matters far less here than the week you choose. That is not a contradiction: March is among the best months Kota Kinabalu has, and it is still hard going. This is a city with no easy season rather than a city you have caught at a bad time.

Rain on 15 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 85% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 25 days top 30 °C, making the heat continuous rather than occasional; the day barely swings — 5.7 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest March day reached 33.3 °C and the coldest night fell to 21.4 °C, and the wettest single day dropped 92 mm — roughly 75% of the month's rain in one day.

March is moderately variable: 20 mm in the driest year against 331 mm in the wettest, around an average of 123 mm. Roughly two Marchs in three land near that average, and the third does something else entirely.

Wind is light at 5.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 85% is the real story though — it is the number that decides how the day feels, not the 30.8 °C.

How March sits in the year

Temperatures hold steady either side: 30.1 °C in February, 30.8 here, 31.5 in April. Nothing about the timing within the month matters much.

Daylight in March

Kota Kinabalu sits close enough to the equator that daylight barely moves all year — 12.1 hours in March, against a range of just 0.7 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 27.5 °C in March — warm enough that the water offers no relief from the heat. The sea peaks at 30 °C in May and bottoms out at 27 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut. March is the value pick for Kota Kinabalu: it scores within 10 points of February without carrying February's prices.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

March in Kota Kinabalu versus nearby

If Kota Kinabalu is one option among several, the nearby comparison is worth making. Sandakan is close enough to be a coin toss — 2.6 °C cooler, 5 days more rain. Zamboanga is a better bet in March — within a degree on temperature, the same number of rain days.

So: March works, with February the better month by 10 points if the dates can move. If they cannot, nothing here should stop you booking.
