Weather in Bunbury in October

Prime time. October is about as good as Bunbury gets. Highs average 20.5 °C, lows 10.8 °C, and rain falls on 8 days — nothing in the month is working against you.

October ranks 5 of 12 in Bunbury: past the worst of the year but short of November, which is the month to book if the dates are open.

Rain on 8 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. 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. Across the twenty years measured, the hottest October day reached 30.6 °C and the coldest night fell to 4.5 °C.

October is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest October on record still delivered 81 mm against 15 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 40 mm average is a reasonable planning figure, not a promise.

Wind is light at 12.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 75%, high enough to notice on the warm days without dominating them.

How October sits in the year

The month is on the way up: 2.9 °C warmer than September, and November adds another 4 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short. Rain has already shifted: 6 days fewer than September had.

Daylight in October

12.9 hours of daylight, gaining 1 hours across the month. That is between Bunbury's extremes of 14.3 and 10 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 19 °C in October — swimmable, but it takes a moment to commit. The sea peaks at 22.7 °C in March and bottoms out at 18.7 °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, May is the trade worth considering — 12 points weaker on weather, and materially quieter.

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

October in Bunbury versus nearby

If Bunbury 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, 1 day less rain. Albany is the weaker option in October — 2.5 °C cooler, 4 days more rain.

So: October is effectively as good as it gets here — 3 points behind November, which is inside the margin where the weather stops being the deciding factor and price starts being it.
