Weather in Tamworth in December

Shoulder season. December is shoulder season in Tamworth — cheaper, quieter, and a genuine gamble. Highs average 31.6 °C, lows 17.1 °C, and rain falls on 12 days — nothing in the month is working against you.

December ranks 10 of 12 — near the bottom of Tamworth's year. April is the month that works, and the swing between the two is 44 points, which is a different holiday rather than a slightly better one.

Rain on 12 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 31.6 °C days and 17.1 °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: 7 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest December day reached 41.9 °C and the coldest night fell to 7.6 °C, and the wettest single day dropped 52 mm — roughly 54% of the month's rain in one day.

December is moderately variable: 12 mm in the driest year against 191 mm in the wettest, around an average of 96 mm. Roughly two Decembers in three land near that average, and the third does something else entirely.

Wind is light at 9.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 53%.

How December sits in the year

The month is on the way up: 1.8 °C warmer than November, and January adds another 2.4 °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 Tamworth's year: 14.1 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

With no coast nearby, the year swings a fair way — 29.5 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage. Within December itself the daily swing is 14.5 °C, so mornings and afternoons need different clothes.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

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

December in Tamworth versus nearby

If Tamworth is one option among several, the nearby comparison is worth making. Armidale is a better bet in December — 5.9 °C cooler, 3 days more rain. Maitland is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: December is a compromise. April is 36 points better and is what Tamworth is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
