Visas & entry
A guide to Cape Byron Lighthouse, mainland Australia's most easterly point, recommends arriving 30-40 minutes before sunrise to catch the full color show and to be among the first people there, since crowds and parking both fill up fast later in the day. Their tip for the parking squeeze near the lighthouse itself: park at Clarkes Beach instead and walk the full circuit up and back, which also turns the visit into more of a proper coastal walk than a quick photo stop.
Traveller notes on Byron Bay
What people who have been say about the place — the year-round notes first, then month by month.
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.
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.
