Conditions at Santa Cruz in April
April: The North-Northwest Machine
April is a transition month, but it still delivers a surprising amount of energy. The average swell is 6.6ft (2.0m) with a period of 11.1s, so it's rideable and punchy rather than huge. The swell direction is extremely focused: NW accounts for 28.0%, NNW for 20.0%, WNW for 21.3% and W for 6.4%, totaling 75.7% from the preferred quarter. The distribution favors 3.3-6.6ft (1-2m) waves, with some 6.6-8.2ft (2-2.5m) sets still showing up from lingering North Atlantic lows.
The wind, however, is the problem. Ideal surf conditions drop to just 11%, as the offshore easterly sector collapses to around 8% and NNW onshores blow 26.9% of the time. As the continent warms, the thermal gradient creates a daily afternoon north-northwesterly that chops up the surface. Air temperatures average 14.7°C (min 7.1°C, max 28.4°C), precipitation is 1.88 mm/day and water temperature rises to 15.4°C. Dawn patrol is essential for finding clean lines before the wind ruins the surface.
