カンガルー島の月別の天気

January is the busy month and the hot one - South Australians put the worst of the heat in late January and early February, and warn that away from a sea breeze the island bakes like the mainland during a heatwave. Our row's 25.7C monthly average is the Southern Ocean doing its work most days; the heatwave is what the average hides. The advice that actually changes a trip is about wildlife, which is the reason most people come: in midsummer the animals are largely nocturnal, so dawn and dusk are when you see them and the middle of the day is when you do not. South-easterlies run November to March, which our 23 kph reflects. The record: 14.2C nights, 21.4mm across 3.4 precipitation days, 12 hours of sun, a 19.6C sea and AQI 27.

Kangaroo Island's forum calls February usually the hottest month in the south, part of a Mediterranean climate with warm summer days that rarely turn genuinely uncomfortable. Regulars are split on how much to love it — some rate February among the best months, others avoid it for the heat — and are unanimous that wind off the ocean is a constant here year-round, worth a windbreaker regardless of season.

March is the month Kangaroo Island regulars name first, with late March into early April the part they single out - warm enough, and the wildlife about. Their caution is that the weather here is changeable at any time of year and the wind is the constant: cool or downright cold off the ocean whatever the season, with south-easterlies running from November through March, which is precisely the stretch March closes. Our row puts that at 22.2 kph. What March does reliably deliver is dryness - 2.2 precipitation days carrying 11.3mm, very nearly a rainless month. The record: 24C days that feel like 23C, 12.9C nights, 10.5 hours of sun and a 19.8C sea.

Regulars are specific this falls within the lightest-wind stretch of the year here, April through June, early-month visitors commonly reporting comfortable low-20s temperatures and plenty of sunshine even as evenings turn genuinely chilly. Our row backs that mild, genuinely dry read, 21.6C over 11.1C nights feeling 9C, with rain minimal at 22.5mm across 4.3 days and a real 20.2 kph wind. Regulars are consistent golden autumn sunsets are a real late-afternoon highlight this time of year, sea conditions staying genuinely calm and benign for anyone planning boat trips or coastal walks. This remains one of the better windows to visit overall. The sea sits at a mild 18.5C. The record: 9.1 hours of sun, humidity 70 percent and AQI 25.

Forum posters describe August as cold, windy and often rainy, with daytime temperatures commonly cited around 10-15C and a noticeable drop by late afternoon - a proper windproof jacket layered over a warm jumper, plus a beanie and gloves, is standard advice. Posters do note sunny morning stretches remain possible even within an otherwise unsettled week, and that quick, strong weather fronts are typical this time of year, with forecasts only considered reliable a few days out. The clear upside posters highlight: winter brings lush green countryside, flowing rivers and genuinely excellent wildlife viewing, with land mammals more likely to be seen out and about during the day rather than confined to dawn, dusk and night - and no mosquitoes to contend with.

Spring here is warm with occasional cool days and scattered rain, mostly fine, mid-twenties with the odd hotter day - which our row backs almost exactly at 21.8C reading as 21C, with 25.8mm across 5.2 days. The wildlife and the wildflowers are both at their best now, regulars say, more out and about than any other season. The one constant they will not let a visitor forget is the wind - cool, sometimes cold, off the ocean at any time of year, with southeasterlies typical from November through March - and our column carries a real 23.4 kph average. The sea is 16.8C, cool enough to be a look-don't-swim proposition for most. The record: humidity 67 percent, 11.7 hours of sun and AQI 28.

Regulars set expectations downward for December and are right to: not cold by northern standards, but not especially hot either, and nobody comes here to sunbathe. Wind is the constant - cool or cold off the ocean at any time of year, with south-easterlies usual from November through March and the calmest stretch falling in April to June. Our row measures it at 23.4 kph against 24.4C days that drop to 11.9C at night, and puts the sea at 17.9C, which settles the swimming question. What the month does offer is dry, bright weather for the wildlife: 22.8mm across 3.7 days and 12.3 hours of sun inside 14.5 of daylight. The record: humidity 66 percent and AQI 27.
