Conditions at North Stradbroke Island in June
June: The Core Season Arrives
June marks the true heart of North Stradbroke Island's surf year. Average swell holds at 1.2m (4ft), but the period is 9.1s and the direction is beautifully spread across the swell window: SE (19%), ESE (19%), SSE (18%) and E (14%). The South Pacific High has shifted north, allowing more W/SW/WSW winds to slip under the island, and ideal offshore flow now occurs 23% of the time. The onshore E/ESE/SE/SSE block is down to around 37% of the wind rose, and those winds are often lighter. Sea surface temperature falls to 22.5°C, air temps average 20.0°C, and rainfall is 3.05mm/day. The result is consistent, clean 3-5ft (0.9-1.5m) surf with occasional bigger sets from S/SE groundswell. This is the month to start planning your trip.
