Weather in Kalgoorlie in March

A good month. March is a solid month to be in Kalgoorlie. Highs average 31.2 °C, lows 15.7 °C, and rain falls on 4 days — nothing in the month is working against you.

March ranks 8 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. Pack for 31.2 °C days and 15.7 °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: 7 days clear 35 °C, so a serious heatwave is normal rather than notable; 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 March day reached 41.7 °C and the coldest night fell to 5.6 °C, and the wettest single day dropped 71 mm — roughly 245% of the month's rain in one day.

This is the volatile part. March rainfall has ranged from 1 mm to 101 mm across the twenty years measured — a 100 mm spread around an average of 29 mm. The average is real but almost no individual March looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 12.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 47%.

How March sits in the year

The month is on the way down: 3.3 °C cooler than February, with April dropping another 3.8 °C. The first week and the last are not the same trip.

Daylight in March

12.3 hours of daylight, losing 0.9 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 March itself the daily swing is 15.6 °C, so mornings and afternoons need different clothes.

How busy it gets

Shoulder. The value months — prices ease off and you get the place closer to itself.

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

March in Kalgoorlie versus nearby

If Kalgoorlie is one option among several, the nearby comparison is worth making. Perth is a better bet in March — 5.3 °C cooler, 1 day less rain. Albany is a better bet in March — 9 °C cooler, 4 days more rain.

So: March is a compromise. May is 22 points better and is what Kalgoorlie is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
