Conditions at Long Beach in April
April: Softer South Swells Arrive
April marks a clear transition at Long Beach. The average wave height drops to 4ft (1.3m), and the average period holds at 7.5s. The swell direction shifts decisively into the south/southeast quadrant: SSE is 12.7%, S jumps to 16.5%, and SSW adds 7.9%, while E, ESE and SE all hover around 11-14%. There is still enough size in the 3-5ft (1-1.5m) class to make things fun, but the long-period winter groundswells are getting harder to come by.
Winds are mixed. The offshore N/NW flow is weakening: NW and NNW are down to 9.1% each, while S and SSW winds rise to 8.9% and 9.1%. Ideal surf wind is 27%, still workable but less reliable than winter. Air temperature averages 8.8°C and water temperature warms to 8.2°C. Precipitation is 3.38 mm/day. April is a shoulder month where a good warm-front passage or late-season Nor'easter can still produce quality waves, but the default is smaller, more wind-swell-influenced surf.
