Conditions at Killer Point in April
April: Transition Begins, Swell Still Present
April marks a clear shift in character at Killer Point. The average swell height is still a respectable 2.0m (6.6ft), but the mean period drops to 10.9s, a sign that the long-period groundswell train is weakening. The wave direction becomes much more NNW-dominated, with NNW at 46.3% and NW at 23.9%. While the waves remain solid in height, the shorter period means they lack the punch and organization of the winter months.
Wind conditions take a big step back. The ideal offshore window drops to only 26%, as the Azores High starts to build and adds a persistent northerly flow. NNW winds blow 35.1% of the time and NW 18.7%, which puts the beach under more onshore/cross-shore pressure. Drying conditions arrive too: precipitation falls to 0.42mm/day, air temp rises to 18.1°C and water holds at 17.1°C. April is still worth checking, especially for smaller groundswell, but the quality control is becoming more selective.
