Conditions at Shark Rock Pier in April
April: Power Building, Consistency Fades
April marks a real shift. Average wave height climbs to 6.9ft (2.1m) and the period lengthens to a powerful 11.7s. Swell distribution still favors SSW at 27.8%, but S (16.2%) and SW (11.6%) combine to reinforce the southerly dominance; SE/SSE and ESE sources also contribute. The number of waves over 8.2ft (2.5m) begins to appear more regularly, especially from the SW sector, so this is the first month where the pier can see some serious winter-style sets.
Ideal winds drop to 25%, as the WSW (18.8%) and W (11.7%) flows become more prominent. While WSW is offshore and welcome, strong ENE/E sea breezes (13.1% and 11.1%) create a more mixed bag. Water temperature falls to 18.8°C and air temps to 19.8°C. April rewards surfers who are selective; the SSW/SW groundswell lines on the back side of a cold front can be absolute freight trains.
