Het weer in Byron Bay (Byron) in maart

Brisbane forum regulars call March fine to visit, still the tail of the wet season rather than clear of it: “southern Queensland is good in March, though more humid,” with the end of the wet season typically meaning “a possible afternoon storm after a hot humid day rather than weeks of rain.” Regulars who visit annually in late March describe it as “mostly lovely and sunny, great for beaches, hikes and outdoor dining” with just a few shower days mixed in. Summer clothes cover most of the trip, though some visitors used to warmer conditions add a light jumper on evenings that dip under 22°C. Our record: 27.7°C days, 20.5°C nights, 16 rain days, 79.3% humidity and a 27.2°C sea — warm, humid and genuinely wet nearly half the month's days, backing the “still wet season, but manageable” read over the purely sunny framing.

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.
