April: Offshore Perfection and Fading Size
April ushers in spring's classic pattern. Average swell height backs down to 2.0m (6.5ft) but the period remains respectable at 12.3s. WNW contribution surges to 50.0%, with W at 21.2% and WSW at 5.8%, so the spot still sees regular chest-to-head-high-plus sets. The big story is wind: ideal conditions 70% of the time, with NW (24.7%), WNW (23.3%), NNW (12.3%) and W (13.7%) dominating. This creates long windows of offshore or clean cross-offshore flow, making the Lane look like a postcard. Rain is much less frequent (1.27mm/day), air temps average 12°C, and upwelling drops water temperature to a chilly 11.5°C. Expect glassy mornings and crisp, hollow takeoffs.
