Väder i Brisbane i september

Brisbane's forum rates September as genuine spring — warm days, mild nights, mostly dry, with locals already swimming by this point in the season. Regulars note school holidays kick in around the 20th, so the first half of the month tends to run noticeably quieter than the second.

Regulars are direct that this counts as winter here only by Australian standards, with glorious sun-filled days offset by nights cool enough that a jumper is worth packing. Our row backs that mild-by-day, cool-by-night read, 22.1C over 11.7C nights feeling 10C, with 52.8mm of rain across just 5.3 days. Regulars are consistent that a rainy day bad enough to actually derail plans is genuinely unusual this time of year, making this a reliable month for outdoor sightseeing despite the cooler evenings. The sea still sits at a comfortable-for-some 18.4C, though most regulars treat it as too cool for a casual swim without a wetsuit. The record: humidity 74 percent, 8.5 hours of sun, a 13.4 kph wind and AQI 38.

Regulars call this the reverse of the wet, humid summer here - cool, sunny, dry days that rarely get spoiled by rain, with the reliably blue skies people move here for. The exception they name is specific: the end of July into early August can bring the coldest run of the winter, overnight lows of 4 to 8C and daytime highs around 18C under a westerly wind that turns bitterly cold despite the sun. Our row averages both halves at 22.1C over 11C, with 43.9mm across 5.2 days - one of the drier and calmer months of this coast's year. The sea holds 17.3C, cool rather than cold. The record: humidity 72 percent, 8.5 hours of sun, a 13.6 kph wind and AQI 33.

May is late autumn here and regulars describe it in two halves of a day rather than two halves of a month: glorious while the sun is up, cooler once it is not, so the packing list is a t-shirt with a light long-sleeve over it and something for the evening. Our row gives 24.4C days falling to 14.4C nights, which is the ten-degree gap behind that advice. The summer humidity has gone - ours reads 75 percent against the wet season's higher figures - and rain has thinned to 69.1mm across 6.8 days. The sea holds 19.5C, swimmable for the acclimatised rather than warm. The record: 8.6 hours of sun inside 10.8 of daylight, a 13.3 kph wind and AQI 33.

August is the coldest month of the Brisbane year and the forum is genuinely split on it. The optimists describe it as glorious - bright blue skies and low-20s days, which our row's 23.6C average high supports - and point out that this is when you can do a bush walk or a theme park without turning into a dripping mess. The objectors blame the westerly wind, which can make an 18C day feel bitter, and one regular names August among the worst months to visit for that reason alone, suggesting you wait for September or October. Their 4 to 8C overnight figures run colder than our row's 11.5C, so read those as the cold snaps rather than the month. Swimming, both sides agree, is out. The record: 3.9 precipitation days carrying 28.7mm, 9.5 hours of sun and an 18.9C sea.
