Weather in Kalgoorlie in July

Prime time. July is about as good as Kalgoorlie gets. Highs average 18.1 °C, lows 5 °C, and rain falls on 4 days — nothing in the month is working against you.

July ranks 6 of 12 in Kalgoorlie: past the worst of the year but short of May, which is the month to book if the dates are open.

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 July reaches 30 °C. Across the twenty years measured, the hottest July day reached 27.2 °C and the coldest night fell to -0.7 °C, and the wettest single day dropped 28 mm — roughly 127% of the month's rain in one day.

July is moderately variable: 3 mm in the driest year against 51 mm in the wettest, around an average of 22 mm. Roughly two Julys in three land near that average, and the third does something else entirely.

Wind is light at 10.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 64%.

How July sits in the year

Temperatures hold steady either side: 18.7 °C in June, 18.1 here, 20.3 in August. Nothing about the timing within the month matters much.

Daylight in July

July sits at the dark end of Kalgoorlie's year — 10.3 hours of daylight against 14.1 at midsummer, gaining 0.4 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.

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.

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.

July in Kalgoorlie versus nearby

If Kalgoorlie is one option among several, the nearby comparison is worth making. Perth is the weaker option in July — within a degree on temperature, 11 days more rain. Albany is the weaker option in July — 2.1 °C cooler, 14 days more rain.

So: July works, with May the better month by 7 points if the dates can move. If they cannot, nothing here should stop you booking.
