Weather in Bandar Lampung in May

Indonesia · 20-year averages, May

Shoulder season. May is shoulder season in Bandar Lampung — cheaper, quieter, and a genuine gamble. You should expect rain on 18 days of the month, which is more days wet than dry.

May ranks 7 of 12 in Bandar Lampung: past the worst of the year but short of August, which is the month to book if the dates are open.

Rain on 18 days, 3 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 86% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 5 days top 30 °C — hot spells arrive, but they break; the day barely swings — 4.3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest May day reached 31.5 °C and the coldest night fell to 23.4 °C, and the wettest single day dropped 48 mm — roughly 42% 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 190 mm against 33 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 113 mm average is a reasonable planning figure, not a promise.

Wind is light at 4.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 86% is the real story though — it is the number that decides how the day feels, not the 29.3 °C.

How May sits in the year

Temperatures hold steady either side: 29.1 °C in April, 29.3 here, 29 in June. Nothing about the timing within the month matters much. Rain is the thing that moves: June brings 5 days less of it, so pushing the dates later buys drier weather.

Daylight in May

Bandar Lampung sits close enough to the equator that daylight barely moves all year — 11.9 hours in May, against a range of just 0.6 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 29.6 °C in May — 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.

May in Bandar Lampung versus nearby

If Bandar Lampung is one option among several, the nearby comparison is worth making. Jakarta is close enough to be a coin toss — within a degree on temperature, 7 days more rain. Palembang is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: May is a compromise. August is 20 points better and is what Bandar Lampung is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
