Weather in Kalgoorlie in August

Prime time. August is about as good as Kalgoorlie gets. Highs average 20.3 °C, lows 5.8 °C, and rain falls on 4 days — nothing in the month is working against you.

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

Rain falls on only 4 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average August reaches 30 °C. Across the twenty years measured, the hottest August day reached 31.7 °C and the coldest night fell to 0.5 °C, and the wettest single day dropped 29 mm — roughly 145% of the month's rain in one day.

August is moderately variable: 4 mm in the driest year against 61 mm in the wettest, around an average of 20 mm. Roughly two Augusts in three land near that average, and the third does something else entirely.

Wind is light at 11.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 58%.

How August sits in the year

The month is on the way up: 2.2 °C warmer than July, and September adds another 3.7 °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

11 hours of daylight, gaining 0.8 hours across the month. That is between Kalgoorlie's extremes of 14.1 and 10.2 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 31.4 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage. Within August itself the daily swing is 14.5 °C, so mornings and afternoons need different clothes.

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 Kalgoorlie versus nearby

If Kalgoorlie is one option among several, the nearby comparison is worth making. Perth is the weaker option in August — 2.7 °C cooler, 10 days more rain. Albany is the weaker option in August — 4.2 °C cooler, 14 days more rain.

So: August is effectively as good as it gets here — 1 points behind May, which is inside the margin where the weather stops being the deciding factor and price starts being it.
