Conditions at North Stradbroke Island in July

July: Winter Gold Standard

If June is the engine room, July is the tuning session. Average swell is 1.1m (3-4ft), but the period remains high at 9.1s and the largest chunks of swell come from SE (18%) and SSE (18%), backed by ESE (15%) and E (13%). Ideal wind for surfing peaks at 26% - the highest all year - thanks to frequent WSW/W and NNW land breezes. Rain drops to just 1.68mm/day, air temps are cool at 19.1°C, and water temp falls to 21.2°C. The consistent offshore flow grooms the longer-period SE/SSE swell into beautifully lined-up peaks. On the best days, the island offers some of the most user-friendly yet powerful surf of the year.
