Weather in Jepara in June
Indonesia · 20-year averages, June
A good month. June is a solid month to be in Jepara. Highs average 29.3 °C, lows 26.3 °C, and rain falls on 14 days — nothing in the month is working against you.
June ranks 4 of 12 in Jepara: 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: 14 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Pack for 29.3 °C days and 26.3 °C nights; the spread matters more here than any single number.
What the averages hide
Averages flatten a month, and this one hides a few things: 6 days top 30 °C — hot spells arrive, but they break; the day barely swings — 3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 31.4 °C and the coldest night fell to 24 °C, and the wettest single day dropped 58 mm — roughly 64% of the month's rain in one day.
This is the volatile part. June rainfall has ranged from 2 mm to 265 mm across the twenty years measured — a 263 mm spread around an average of 90 mm. The average is real but almost no individual June looks like it, so treat the figure as the middle of a wide range rather than a forecast.
Wind is light at 12.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 78%, high enough to notice on the warm days without dominating them.
How June sits in the year
Temperatures hold steady either side: 29.4 °C in May, 29.3 here, 29.4 in July. Nothing about the timing within the month matters much. Rain is the thing that moves: July brings 6 days less of it, so pushing the dates later buys drier weather.
Daylight in June
Jepara sits close enough to the equator that daylight barely moves all year — 11.7 hours in June, against a range of just 0.8 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.
Sea temperature
The sea sits at about 29.4 °C in June — warm enough that the water offers no relief from the heat. The sea peaks at 29.8 °C in April and bottoms out at 28.1 °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
Shoulder. The value months — prices ease off and you get the place closer to itself.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
June in Jepara versus nearby
If Jepara is one option among several, the nearby comparison is worth making. Semarang is close enough to be a coin toss — within a degree on temperature, 3 days less rain. Surabaya is close enough to be a coin toss — within a degree on temperature, 3 days less rain.
So: June works, with August the better month by 13 points if the dates can move. If they cannot, nothing here should stop you booking.
