Weather in Warrnambool in October

A good month. October works. It is not the peak, but nothing about it fights you. Highs average 16.1 °C, lows 10.8 °C, and rain falls on 11 days — nothing in the month is working against you.

October ranks 7 of 12 in Warrnambool: past the worst of the year but short of January, which is the month to book if the dates are open.

Rain on 11 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 16.1 °C days and 10.8 °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: the day barely swings — 5.3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest October day reached 26.6 °C and the coldest night fell to 7 °C, and the wettest single day dropped 44 mm — roughly 73% of the month's rain in one day.

October is moderately variable: 6 mm in the driest year against 125 mm in the wettest, around an average of 60 mm. Roughly two Octobers in three land near that average, and the third does something else entirely.

Wind sits around 19.2 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity runs at 76%, high enough to notice on the warm days without dominating them.

How October sits in the year

Temperatures hold steady either side: 14.7 °C in September, 16.1 here, 17.8 in November. Nothing about the timing within the month matters much.

Daylight in October

13 hours of daylight, gaining 1.2 hours across the month. That is between Warrnambool's extremes of 14.8 and 9.5 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 13.9 °C in October — too cold to swim without a wetsuit. The sea peaks at 17.9 °C in February and bottoms out at 13.6 °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

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.

October in Warrnambool versus nearby

If Warrnambool is one option among several, the nearby comparison is worth making. Ballarat is a better bet in October — 2 °C warmer, 2 days less rain. Mount Gambier is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

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