Weather in Jepara in April

Shoulder season. April is shoulder season in Jepara — 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 9 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.

Rain on 26 of the month's 30 days, 5 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. Pack for 29 °C days and 27.2 °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: the day barely swings — 1.8 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest April day reached 31 °C and the coldest night fell to 25.1 °C, and the wettest single day dropped 103 mm — roughly 52% 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 300 mm against 88 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 200 mm average is a reasonable planning figure, not a promise.

Wind is light at 9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 81%, high enough to notice on the warm days without dominating them.

How April sits in the year

Temperatures hold steady either side: 28.4 °C in March, 29 here, 29.4 in May. Nothing about the timing within the month matters much. Rain is the thing that moves: May brings 6 days less of it, so pushing the dates later buys drier weather.

Daylight in April

Jepara 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.

Sea temperature

The sea sits at about 29.8 °C in April — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.

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 Jepara versus nearby

If Jepara is one option among several, the nearby comparison is worth making. Semarang is the weaker option in April — within a degree on temperature, 3 days less rain. Surabaya is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: April is a compromise. August is 22 points better and is what Jepara is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
