Weather in Semarang in November

A hard month. November asks something of you. Go in knowing what. You should expect rain on 23 days of the month, which is more days wet than dry.

November ranks 11 of 12 — near the bottom of Semarang's year. July is the month that works, and the swing between the two is 30 points, which is a different holiday rather than a slightly better one.

Rain on 23 of the month's 30 days, 7 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 32.1 °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: 24 days top 30 °C, making the heat continuous rather than occasional. Across the twenty years measured, the hottest November day reached 39.2 °C and the coldest night fell to 23.4 °C, and the wettest single day dropped 62 mm — roughly 30% of the month's rain in one day.

November is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest November on record still delivered 359 mm against 54 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 205 mm average is a reasonable planning figure, not a promise.

Wind is light at 5.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 77%, high enough to notice on the warm days without dominating them.

How November sits in the year

The month is on the way down: 2.6 °C cooler than October, with December dropping another 1.8 °C. The first week and the last are not the same trip. Rain has already shifted: 8 days more than October had.

Daylight in November

Semarang sits close enough to the equator that daylight barely moves all year — 12.4 hours in November, 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 November — warm enough that the water offers no relief from the heat. The sea peaks at 29.9 °C in May and bottoms out at 28.5 °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

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.

November in Semarang versus nearby

If Semarang is one option among several, the nearby comparison is worth making. Jepara is a better bet in November — 2.4 °C cooler, 3 days more rain. Surabaya is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: November is a compromise. July is 24 points better and is what Semarang is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
