Weather in Broome in August

A good month. August is a solid month to be in Broome. Highs average 32.5 °C, lows 16.9 °C, and rain falls on 0 days — nothing in the month is working against you.

August ranks 3 of 12 in Broome. Only June scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain is not a factor worth planning around this month. Pack for 32.5 °C days and 16.9 °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: 27 days top 30 °C, making the heat continuous rather than occasional; the day swings 15.6 °C from low to high, which means one bag has to cover both. Across the twenty years measured, the hottest August day reached 38.8 °C and the coldest night fell to 11.5 °C, and the wettest single day dropped 32 mm — roughly 1067% of the month's rain in one day.

August is dependably dry, and that reliability is the point: across the twenty years measured, the wettest August on record still only managed 38 mm, and the driest managed 0 mm. There is no meaningful variability to plan around, which makes this one of the few months anywhere that you can build a fixed outdoor itinerary against without a fallback. The wettest single day in twenty years of Augusts brought 32 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.

Wind is light at 11 km/h, so the temperature on the page is close to the temperature on your skin, and the air is dry at 40% humidity, which makes the heat far more bearable than the same figure somewhere humid — and dehydrates you faster than you expect.

How August sits in the year

The month is on the way up: 1.9 °C warmer than July, and September adds another 3.6 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in August

August sits at the dark end of Broome's year — 11.5 hours of daylight against 13.2 at midsummer, gaining 0.4 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

Sea temperature

The sea sits at about 24.7 °C in August — warm enough to stay in as long as you like. The sea peaks at 30.2 °C in March and bottoms out at 24.7 °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

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

August in Broome versus nearby

If Broome is one option among several, the nearby comparison is worth making. Labuan Bajo is close enough to be a coin toss — 2 °C cooler, 4 days more rain. Darwin is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: August works, with June the better month by 8 points if the dates can move. If they cannot, nothing here should stop you booking.
