Weather in Geraldton in October

Prime time. If you get to pick your dates, October is the one. Highs average 20.4 °C, lows 17.4 °C, and rain falls on 3 days — nothing in the month is working against you.

October ranks 6 of 12 in Geraldton: past the worst of the year but short of January, which is the month to book if the dates are open.

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: it never really gets hot: not one day in an average October reaches 30 °C; the day barely swings — 3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest October day reached 30.1 °C and the coldest night fell to 12.8 °C.

This is the volatile part. October rainfall has ranged from 2 mm to 78 mm across the twenty years measured — a 76 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 sits around 22 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity is unremarkable at 74%.

How October sits in the year

Temperatures hold steady either side: 19.4 °C in September, 20.4 here, 22.1 in November. Nothing about the timing within the month matters much.

Daylight in October

12.7 hours of daylight, gaining 0.8 hours across the month. That is between Geraldton's extremes of 14 and 10.3 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 20 °C in October — swimmable, but it takes a moment to commit. The sea peaks at 23.7 °C in March and bottoms out at 19.9 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, September is the trade worth considering — 10 points weaker on weather, and materially quieter.

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

October in Geraldton versus nearby

If Geraldton is one option among several, the nearby comparison is worth making. Perth is close enough to be a coin toss — within a degree on temperature, 4 days more rain. Bunbury is the weaker option in October — within a degree on temperature, 5 days more rain.

So: October is effectively as good as it gets here — 2 points behind January, which is inside the margin where the weather stops being the deciding factor and price starts being it.
