Weather in Jakarta in February

Shoulder season. February sits in between. You will get good days and you will lose some. You should expect rain on 27 days of the month, which is more days wet than dry.

February ranks 6 of 12 in Jakarta: past the worst of the year but short of August, which is the month to book if the dates are open.

Rain on 27 of the month's 28 days, 13 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Natural fibres and a second shirt for the day. At 86% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 3.1 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest February day reached 31.3 °C and the coldest night fell to 23.4 °C, and the wettest single day dropped 115 mm — roughly 30% of the month's rain in one day.

February is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest February on record still delivered 597 mm against 201 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 387 mm average is a reasonable planning figure, not a promise.

Wind is light at 10.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 86% is the real story though — it is the number that decides how the day feels, not the 28.5 °C.

How February sits in the year

Temperatures hold steady either side: 28.8 °C in January, 28.5 here, 29.1 in March. Nothing about the timing within the month matters much.

Daylight in February

Jakarta sits close enough to the equator that daylight barely moves all year — 12.3 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 28.6 °C in February — warm enough that the water offers no relief from the heat. The sea peaks at 29.9 °C in May and bottoms out at 28.6 °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

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.

February in Jakarta versus nearby

If Jakarta is one option among several, the nearby comparison is worth making. Bandung is close enough to be a coin toss — 2.3 °C cooler, the same number of rain days. Bandar Lampung is close enough to be a coin toss — within a degree on temperature, 3 days less rain.

So: February works, with August the better month by 18 points if the dates can move. If they cannot, nothing here should stop you booking.
