バイロンベイ 9月の天気

Regulars call September one of the best months here - mid-20s, usually rain-free, the odd windy day - and then split it by a school calendar. The Queensland holidays take the last two weeks, so prices climb and the theme parks fill; the first fortnight is the same weather without any of that. Our row supports the weather half at 24.2C over 14.9C with 40.3mm across 5 days. On the water they are careful: about 22C, which they call a bit cool but fine for the beach, and our 21.2C agrees - children mind it less than adults do. The record: humidity 73 percent, 10.3 hours of sun, a 16.6 kph wind and AQI 42.

Forum posters describe July temperatures in Byron Bay as commonly around 19-20C most days, mild for the depths of Australian winter thanks to the town's far-northern New South Wales location, warmer overall than beaches further south. Posters are consistent that Byron Bay is worth visiting any time of year, with shorts still perfectly reasonable daywear, though a wetsuit becomes genuinely necessary for winter swimming or surfing. Posters recommend long pants or, for women, tights under a skirt for cooler evening outings. Posters generally rate July as mild and pleasant by regional winter standards for Byron Bay, workable for outdoor exploring even if the water itself runs cold.

January in Byron Bay is hot, wet and packed all at once. The forum's summary is that it either rains or is stinking hot, with school holidays running to late January, accommodation at peak prices and booked well ahead, and the town super-packed at weekends. The record backs the wet half: near fourteen rain-days, against 27°C by day and 22 overnight, with the sea at 25. Regulars' fix for the heat is timing — start walks at first light. Their fix for everything else is to come in April or May instead.
