Weather in Albany in December

Prime time. December is about as good as Albany gets. Highs average 20.8 °C, lows 15.4 °C, and rain falls on 6 days — nothing in the month is working against you.

December ranks 3 of 12 in Albany. Only January scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain falls on only 6 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 December reaches 30 °C; the day barely swings — 5.5 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest December day reached 34.2 °C and the coldest night fell to 11 °C, and the wettest single day dropped 38 mm — roughly 115% of the month's rain in one day.

December is moderately variable: 9 mm in the driest year against 91 mm in the wettest, around an average of 33 mm. Roughly two Decembers in three land near that average, and the third does something else entirely.

Wind sits around 18.2 km/h — a steady breeze rather than a nuisance, and welcome on the warmer days, and humidity is unremarkable at 74%.

How December sits in the year

Temperatures hold steady either side: 19.6 °C in November, 20.8 here, 22.2 in January. Nothing about the timing within the month matters much.

Daylight in December

December is at or near the longest days of Albany's year: 14.5 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 18 °C in December — swimmable, but it takes a moment to commit. The sea peaks at 19.8 °C in February and bottoms out at 16.1 °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.

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

December in Albany versus nearby

If Albany is one option among several, the nearby comparison is worth making. Bunbury is close enough to be a coin toss — 7.6 °C warmer, 3 days less rain. Perth is close enough to be a coin toss — 3.8 °C warmer, 3 days less rain.

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