Het weer in Byron Bay (Byron) in augustus

Regulars call this the last stretch of winter, sunny days in the low-to-mid 20s Celsius the norm even as mornings, evenings and the sea breeze can still push it toward genuinely cool. Our row backs that mild, still-dry read, 22.7C over 12.8C nights feeling 12C, with rain light at 41mm across 4.5 days and humidity at 71 percent. Regulars are consistent the wind specifically is what catches people off guard, a sunny-looking day still needing a windbreaker layer once that sea breeze picks up. This remains a genuinely good month for beach walks and outdoor sightseeing without summer's crowds or heat, though the sea itself stays too cool for most to swim comfortably. The sea sits at 20.4C. The record: 9.6 hours of sun, a 14.7 kph wind and AQI 40.

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.
