Weather in Palembang in May

A hard month. May asks something of you. Go in knowing what. The heat itself is manageable at 30 °C, but 90% humidity is what you will actually feel.

May ranks 12 of 12 — near the bottom of Palembang's year. August is the month that works, and the swing between the two is 18 points, which is a different holiday rather than a slightly better one.

Rain on 19 days, 6 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 90% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 17 days top 30 °C — hot spells arrive, but they break; the day barely swings — 5.9 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest May day reached 31.8 °C and the coldest night fell to 21.3 °C, and the wettest single day dropped 80 mm — roughly 45% of the month's rain in one day.

May is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest May on record still delivered 315 mm against 44 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 178 mm average is a reasonable planning figure, not a promise.

Wind is light at 2.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 90% is the real story though — it is the number that decides how the day feels, not the 30 °C.

How May sits in the year

Temperatures hold steady either side: 29.9 °C in April, 30 here, 29.5 in June. Nothing about the timing within the month matters much. Rain has already shifted: 6 days fewer than April had.

Daylight in May

Palembang sits close enough to the equator that daylight barely moves all year — 12 hours in May, 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

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.

May in Palembang versus nearby

If Palembang is one option among several, the nearby comparison is worth making. Bandar Lampung is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Jakarta is close enough to be a coin toss — within a degree on temperature, 6 days more rain.

So: May works, with August the better month by 18 points if the dates can move. If they cannot, nothing here should stop you booking.
