Weather in Traralgon in December

Prime time. If you get to pick your dates, December is the one. Highs average 26.1 °C, lows 12.7 °C, and rain falls on 11 days — nothing in the month is working against you.

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

Rain on 11 days, 2 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: 8 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest December day reached 42.6 °C and the coldest night fell to 6.5 °C, and the wettest single day dropped 47 mm — roughly 62% of the month's rain in one day.

December is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest December on record still delivered 158 mm against 21 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 76 mm average is a reasonable planning figure, not a promise.

Wind is light at 0.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 63%.

How December sits in the year

The month is on the way up: 2.5 °C warmer than November, and January adds another 3.5 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in December

December is at or near the longest days of Traralgon's year: 14.8 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

Despite being inland, the year stays fairly even: 22.8 °C between the year's warmest afternoons and coldest nights.

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 Traralgon versus nearby

If Traralgon is one option among several, the nearby comparison is worth making. Melbourne is close enough to be a coin toss — 2.2 °C cooler, 2 days less rain. Wodonga is close enough to be a coin toss — 3.7 °C warmer, 4 days less rain.

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