Weather in Whyalla in October

Prime time. If you get to pick your dates, October is the one. Highs average 24.3 °C, lows 13 °C, and rain falls on 3 days — nothing in the month is working against you.

October is the highest-scoring month of the twelve. The nearest rival is April, and the month at the other end of the year is January.

Rain falls on only 3 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: 5 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest October day reached 36.2 °C and the coldest night fell to 6.8 °C.

This is the volatile part. October rainfall has ranged from 0 mm to 61 mm across the twenty years measured — a 61 mm spread around an average of 16 mm. The average is real but almost no individual October looks like it, so treat the figure as the middle of a wide range rather than a forecast.

Wind is light at 15.3 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 55%.

How October sits in the year

The month is on the way up: 3.1 °C warmer than September, and November adds another 3.2 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in October

12.9 hours of daylight, gaining 1 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

Despite being inland, the year stays fairly even: 23.7 °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. If the dates are flexible, August is the trade worth considering — 13 points weaker on weather, and materially quieter.

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

October in Whyalla versus nearby

If Whyalla is one option among several, the nearby comparison is worth making. Gawler is close enough to be a coin toss — within a degree on temperature, 2 days more rain. Adelaide is close enough to be a coin toss — 2.2 °C cooler, 2 days more rain.

So: October is the answer for Whyalla. If it is booked out or priced out, April is the next best thing at 1 points behind, and January is the month to keep off the shortlist.
