Weather in Darwin in August

Prime time. August is about as good as Darwin gets. Highs average 30.8 °C, lows 22.7 °C, and rain falls on 0 days — nothing in the month is working against you.

August ranks 3 of 12 in Darwin. Only July 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 30.8 °C days and 22.7 °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: 24 days top 30 °C, making the heat continuous rather than occasional. Across the twenty years measured, the hottest August day reached 34 °C and the coldest night fell to 17 °C.

August is dependably dry, and that reliability is the point: across the twenty years measured, the wettest August on record still only managed 8 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 6 mm. Rain simply is not the variable that decides this trip — heat, crowds and cost are.

Wind is light at 12 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 54%.

How August sits in the year

Temperatures hold steady either side: 30 °C in July, 30.8 here, 32.4 in September. Nothing about the timing within the month matters much.

Daylight in August

Darwin sits close enough to the equator that daylight barely moves all year — 11.7 hours in August, against a range of just 1.4 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: 11.7 °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.

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

August in Darwin versus nearby

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

So: August is effectively as good as it gets here — 4 points behind July, which is inside the margin where the weather stops being the deciding factor and price starts being it.
