Conditions at North Beach in April
April: First Groundswell Flush
April is the first month where long-period energy starts to show up consistently. The average period hits 10.0s and the ideal wind percentage jumps to 40%. Swell heights remain solid at 1.7m (5-6ft), and while the dominant directions swing to SSE (20.0%) and SE (17.5%), the direct E/ESE/ENE window still accounts for 40.6%. This means the spot is often cross-shore rather than head-high clean, but when a straight E/ESE pulse lines up with morning W/SW wind, North Beach is excellent. The NE onshore flow drops to 13.6% and ENE to 10.0%, while SW (9.4%) and WSW (4.2%) increase. Air temps average 23.4°C, water drops slightly to 24.5°C, and rain is just 2.19mm/day - a solid pre-winter surf month.
