Weather in Jakarta in June

Shoulder season. June sits in between. You will get good days and you will lose some. You should expect rain on 17 days of the month, which is more days wet than dry.

June ranks 4 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.

This is persistent light rain rather than storms: 17 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Natural fibres and a second shirt for the day. At 82% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 5 days top 30 °C — hot spells arrive, but they break; the day barely swings — 3.9 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 31.3 °C and the coldest night fell to 22.9 °C, and the wettest single day dropped 34 mm — roughly 36% of the month's rain in one day.

June is moderately variable: 12 mm in the driest year against 219 mm in the wettest, around an average of 95 mm. Roughly two Junes in three land near that average, and the third does something else entirely.

Wind is light at 8.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 82%, high enough to notice on the warm days without dominating them.

How June sits in the year

Temperatures hold steady either side: 29.7 °C in May, 29.4 here, 29.2 in July. Nothing about the timing within the month matters much. Rain has already shifted: 8 days fewer than May had.

Daylight in June

Jakarta sits close enough to the equator that daylight barely moves all year — 11.8 hours in June, 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 29.6 °C in June — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

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

June 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 — 2.8 °C cooler, 2 days less rain. Bandar Lampung is close enough to be a coin toss — within a degree on temperature, 4 days less rain.

So: June works, with August the better month by 14 points if the dates can move. If they cannot, nothing here should stop you booking.
