Byron Bay (Byron) weather in June

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.

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.
