Weather in Bandung in April

Shoulder season. April is shoulder season in Bandung — cheaper, quieter, and a genuine gamble. You should expect rain on 26 days of the month, which is more days wet than dry.

April ranks 7 of 12 in Bandung: past the worst of the year but short of August, which is the month to book if the dates are open.

Rain on 26 of the month's 30 days, 11 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 90% 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 April reaches 30 °C. Across the twenty years measured, the hottest April day reached 29.3 °C and the coldest night fell to 17.3 °C, and the wettest single day dropped 71 mm — roughly 25% of the month's rain in one day.

April is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest April on record still delivered 487 mm against 145 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 285 mm average is a reasonable planning figure, not a promise.

Wind is light at 4.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 90% is the real story though — it is the number that decides how the day feels, not the 26.9 °C.

How April sits in the year

Temperatures hold steady either side: 26.5 °C in March, 26.9 here, 27.1 in May. Nothing about the timing within the month matters much.

Daylight in April

Bandung sits close enough to the equator that daylight barely moves all year — 12 hours in April, 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: 10.8 °C between the year's warmest afternoons and coldest nights. At 714 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly.

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.

April in Bandung versus nearby

If Bandung is one option among several, the nearby comparison is worth making. Jakarta is close enough to be a coin toss — 2.6 °C warmer, 2 days more rain. Bandar Lampung is close enough to be a coin toss — 2.2 °C warmer, 5 days less rain.

So: April is a compromise. August is 23 points better and is what Bandung is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
