Hobart (Tasmania) weather in December

Hobart-forum threads on early December weather describe genuinely pleasant, mild-to-warm days as the norm, but posters are consistent this is still Tasmania, where a chilly, windy afternoon can follow a warm morning with little notice even at the height of summer. One visitor logged a surprising 31C day with barely any humidity, well above the seasonal average, underscoring how variable the month can run year to year. Nights stay genuinely cool regardless of how warm the day got, and a light jacket or spray shell is standing advice for evenings on the waterfront. Kunanyi/Mount Wellington above the city can hold a dusting on its upper slopes even into early summer some years, a real contrast to the mild town below. Regulars call December a great value month, before the peak summer crowds arrive. The record: 21.7C days feeling like 20C, 12C nights, a 17.1C sea, 67 percent humidity and 11.8 hours of sun.

Regulars are direct that Tasmania's famous weather variability is genuinely lived experience here, temperatures swinging from a warm 32.5C one day to as low as 13C the next within the same trip, no reliable pattern to plan around. Our row backs that mild, still-showery average sitting between those extremes, 19.9C over 10.4C nights feeling 8C, with 55.6mm of rain across 8.5 days and humidity at 70 percent. Regulars are consistent brief rain showers are the norm rather than heavy downpours, cloudy skies more common than sunny ones despite the reasonable average temperature. Layers and a proper waterproof shell remain the standard packing advice regardless of the forecast on arrival. The sea sits at a cool 15.5C. The record: 10.8 hours of sun, a 19.2 kph wind and one of the cleanest air readings in this project, AQI 22.

Tasmania-forum threads on October weather split sharply: one visitor calls it the worst month of the year, grey skies, driving rain, sleet and high wind cycling through in a single day, while another calls the same month great, mild and with longer daylight than the depths of winter. Both camps agree spring blossoms are in full bloom regardless of which version of the sky shows up. September and October together are singled out as genuinely windy and blustery months, worth factoring into any outdoor plans along the waterfront or up on the mountain. The standing advice repeated across every thread is to pack for all four seasons in a single day, since Tasmania's weather is called capable of delivering sun, rain and cold within the same afternoon. The record: 18.1C days feeling like 16C, 8.7C nights, 64mm across 11 days, a 13.1C sea, 71 percent humidity and 9.9 hours of sun.

March is the month Tasmania's summer wanes. Regulars describe high teens to low twenties cooling through the month - our row gives 21.7C days over 12.3C nights - and the feeling as a bit of crispness in the air rather than actual cold. February into mid-March is the stretch they name for warm patches, and March, April and sometimes early May can deliver a late Indian summer that is more settled than midsummer. For autumn colour, Mount Field National Park outside Hobart is where Australia's native deciduous tree turns, though that is an April and May event. The record: 7.6 precipitation days carrying 39.2mm, 8.8 hours of sun, a 17.7C sea and AQI 18, the cleanest air in this round.

February is the month the Hobart forum puts first, and it gives reasons rather than vibes: the highest average overnight minimums of the year, the lowest rainfall, the fewest precipitation days, warmer seas and still-long days. Their practical argument is to come in February rather than January, when cars and rooms are both easier to get and cheaper. The standing caution is that Tasmanian weather is changeable whatever the month - the odd 40C day turns up in summer - so a layer for the evening is assumed. MONA is the year-round draw, and the ferry up the Derwent to it is the recommended way there; book it ahead. The record: 22.9C days, 13.2C nights, 4.9 precipitation days, 10.5 hours of sun, a 19.1C river mouth and AQI 18, among the cleanest air in the dataset.
