Weather in Perth in November

Prime time. If you get to pick your dates, November is the one. Highs average 22.4 °C, lows 16.2 °C, and rain falls on 5 days — nothing in the month is working against you.

November ranks 5 of 12 in Perth: 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 5 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

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest November day reached 34.7 °C and the coldest night fell to 10.7 °C, and the wettest single day dropped 25 mm — roughly 100% of the month's rain in one day.

November is moderately variable: 4 mm in the driest year against 66 mm in the wettest, around an average of 25 mm. Roughly two Novembers in three land near that average, and the third does something else entirely.

Wind sits around 19.4 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity is unremarkable at 69%.

How November sits in the year

The month is on the way up: 2.5 °C warmer than October, and December adds another 2.2 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in November

November is at or near the longest days of Perth's year: 13.7 hours of daylight, gaining 0.7 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 20 °C in November — swimmable, but it takes a moment to commit. The sea peaks at 22.9 °C in March and bottoms out at 19 °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

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

November in Perth versus nearby

If Perth is one option among several, the nearby comparison is worth making. Bunbury is close enough to be a coin toss — 2.1 °C warmer, 1 day more rain. Geraldton is close enough to be a coin toss — within a degree on temperature, 3 days less rain.

So: November is effectively as good as it gets here — 5 points behind January, which is inside the margin where the weather stops being the deciding factor and price starts being it.
