Weather in Whyalla in August

Prime time. If you get to pick your dates, August is the one. Highs average 17.8 °C, lows 8.5 °C, and rain falls on 7 days — nothing in the month is working against you.

August ranks 8 of 12 in Whyalla: past the worst of the year but short of October, which is the month to book if the dates are open.

Rain on 7 days, 0 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 17.8 °C days and 8.5 °C nights; the spread matters more here than any single number.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest August day reached 27.4 °C and the coldest night fell to 4 °C.

August is moderately variable: 2 mm in the driest year against 53 mm in the wettest, around an average of 25 mm. Roughly two Augusts in three land near that average, and the third does something else entirely.

Wind is light at 13.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 68%.

How August sits in the year

Temperatures hold steady either side: 16.5 °C in July, 17.8 here, 21.2 in September. Nothing about the timing within the month matters much.

Daylight in August

10.9 hours of daylight, gaining 0.9 hours across the month. That is between Whyalla's extremes of 14.3 and 10 hours, so days are long enough not to constrain the plan.

An inland climate

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut. August is the value pick for Whyalla: it scores within 13 points of October without carrying October's prices.

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