Weather in Sandakan in February

Shoulder season. February is shoulder season in Sandakan — cheaper, quieter, and a genuine gamble. You should expect rain on 18 days of the month, which is more days wet than dry.

Sandakan barely has seasons. February scores 57 out of 100 against a best of 57 in February — a gap small enough that the month you choose matters far less here than the week you choose.

This is wet-season rain: 18 wet days and 7 genuinely heavy ones, which in this climate means concentrated downpours rather than all-day grey. The pattern is usually a clear morning and a loud afternoon, so front-load the day and stop fighting the 3pm hour. 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: it never really gets hot: not one day in an average February reaches 30 °C; the day barely swings — 2.1 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest February day reached 29.3 °C and the coldest night fell to 23.1 °C, and the wettest single day dropped 125 mm — roughly 50% of the month's rain in one day.

This is the volatile part. February rainfall has ranged from 14 mm to 750 mm across the twenty years measured — a 736 mm spread around an average of 250 mm. The average is real but almost no individual February looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 8.4 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 27.7 °C.

How February sits in the year

Temperatures hold steady either side: 27.6 °C in January, 27.7 here, 28.2 in March. Nothing about the timing within the month matters much. Rain has already shifted: 8 days fewer than January had.

Daylight in February

Sandakan sits close enough to the equator that daylight barely moves all year — 11.9 hours in February, 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 27.8 °C in February — warm enough that the water offers no relief from the heat. The sea peaks at 29.7 °C in May and bottoms out at 27.8 °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

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, June is the trade worth considering — 3 points weaker on weather, and materially quieter.

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

February in Sandakan versus nearby

If Sandakan is one option among several, the nearby comparison is worth making. Kota Kinabalu is close enough to be a coin toss — 2.4 °C warmer, 7 days less rain. Zamboanga is a better bet in February — within a degree on temperature, 5 days less rain.

So: February is the answer for Sandakan. If it is booked out or priced out, January is the next best thing at 1 points behind, and May is the month to keep off the shortlist.
