Weather in Jepara in July

A good month. July is a solid month to be in Jepara. Highs average 29.4 °C, lows 25.5 °C, and rain falls on 8 days — nothing in the month is working against you.

July ranks 2 of 12 in Jepara. Only August scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 8 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 29.4 °C days and 25.5 °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: 7 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 July day reached 31.2 °C and the coldest night fell to 23.4 °C, and the wettest single day dropped 42 mm — roughly 89% of the month's rain in one day.

This is the volatile part. July rainfall has ranged from 0 mm to 149 mm across the twenty years measured — a 149 mm spread around an average of 47 mm. The average is real but almost no individual July looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 13.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 75%, high enough to notice on the warm days without dominating them.

How July sits in the year

Temperatures hold steady either side: 29.3 °C in June, 29.4 here, 30 in August. Nothing about the timing within the month matters much. Rain has already shifted: 6 days fewer than June had.

Daylight in July

Jepara sits close enough to the equator that daylight barely moves all year — 11.8 hours in July, 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 28.6 °C in July — 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

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, September is the trade worth considering — 9 points weaker on weather, and materially quieter.

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

July in Jepara versus nearby

If Jepara is one option among several, the nearby comparison is worth making. Semarang is the weaker option in July — 2.4 °C warmer, 1 day less rain. Surabaya is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: July is effectively as good as it gets here — 2 points behind August, which is inside the margin where the weather stops being the deciding factor and price starts being it.
