Byron Bay in December

March through May offers perfect beach weather without the summer crowds – water temps stay around 24°C and accommodation prices drop 30%. September to November brings whale watching season and spring wildflowers, though book early for Splendour in the Grass festival in July. Summer (December-February) means 30°C days, packed beaches, and prices that'll make you wince – a basic hotel room hits $250 per night. Winter (June-August) sees 20°C days perfect for hiking, but the water's too cold for swimming unless you're hardcore. Avoid schoolies week in November when 18-year-olds descend for graduation celebrations. Rain can hit any time, but it usually passes quickly. Pack layers – Byron's weather changes faster than the local gossip.
