Weather in Palembang in August

Shoulder season. August is shoulder season in Palembang — cheaper, quieter, and a genuine gamble. The heat itself is manageable at 30.1 °C, but 87% humidity is what you will actually feel.

August is the highest-scoring month of the twelve. The nearest rival is September, and the month at the other end of the year is May.

Rain on 10 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Natural fibres and a second shirt for the day. At 87% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 18 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest August day reached 32.3 °C and the coldest night fell to 19.6 °C, and the wettest single day dropped 77 mm — roughly 97% of the month's rain in one day.

August is moderately variable: 5 mm in the driest year against 249 mm in the wettest, around an average of 79 mm. Roughly two Augusts in three land near that average, and the third does something else entirely.

Wind is light at 3.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 87% is the real story though — it is the number that decides how the day feels, not the 30.1 °C.

How August sits in the year

Temperatures hold steady either side: 29.5 °C in July, 30.1 here, 30.6 in September. Nothing about the timing within the month matters much.

Daylight in August

Palembang sits close enough to the equator that daylight barely moves all year — 12 hours in August, against a range of just 0.3 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

An inland climate

Despite being inland, the year stays fairly even: 8.1 °C between the year's warmest afternoons and coldest nights.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, June is the trade worth considering — 10 points weaker on weather, and materially quieter.

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

August in Palembang versus nearby

If Palembang is one option among several, the nearby comparison is worth making. Bandar Lampung is a better bet in August — within a degree on temperature, 2 days less rain. Jakarta is a better bet in August — within a degree on temperature, the same number of rain days.

So: August is the answer for Palembang. If it is booked out or priced out, September is the next best thing at 4 points behind, and May is the month to keep off the shortlist.
