Weather in Labuan Bajo in May

Shoulder season. May is shoulder season in Labuan Bajo — cheaper, quieter, and a genuine gamble. Highs average 30 °C, lows 25.4 °C, and rain falls on 14 days — nothing in the month is working against you.

May ranks 5 of 12 in Labuan Bajo: past the worst of the year but short of July, which is the month to book if the dates are open.

This is wet-season rain: 14 wet days and 5 genuinely heavy ones, which in this climate means concentrated downpours rather than all-day grey. The pattern is usually a clear morning and a loud afternoon, so front-load the day and stop fighting the 3pm hour. Pack for 30 °C days and 25.4 °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: 14 days top 30 °C — hot spells arrive, but they break; the day barely swings — 4.5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest May day reached 33 °C and the coldest night fell to 23 °C, and the wettest single day dropped 35 mm — roughly 27% of the month's rain in one day.

May is moderately variable: 12 mm in the driest year against 326 mm in the wettest, around an average of 131 mm. Roughly two Mays in three land near that average, and the third does something else entirely.

Wind is light at 3.9 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 79%, high enough to notice on the warm days without dominating them.

How May sits in the year

Temperatures hold steady either side: 30 °C in April, 30 here, 29.5 in June. Nothing about the timing within the month matters much. Rain is the thing that moves: June brings 6 days less of it, so pushing the dates later buys drier weather.

Daylight in May

Labuan Bajo sits close enough to the equator that daylight barely moves all year — 11.7 hours in May, against a range of just 1 hour across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 29.5 °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

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

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

May in Labuan Bajo versus nearby

If Labuan Bajo is one option among several, the nearby comparison is worth making. Makassar is close enough to be a coin toss — within a degree on temperature, 2 days more rain. Denpasar is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: May is a compromise. July is 21 points better and is what Labuan Bajo is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
