Conditions at Sebastian Inlet in April
April: Trade Winds Turn Onshore
April marks a noticeable step down in surf quality. The average swell height remains around 2.5ft (0.8m) with an 8.1s period, but the dominant directions shift further south and the wind becomes more uncooperative. E swell rules the wave rose at 28.0%, followed by ENE at 20.6%, but ESE has already climbed to 14.0%. Favorable wind drops to 26%, and the trade wind pattern strengthens: E (11.5%), ESE (11.2%), SE (9.8%) and ENE (8.8%) all appear with increasing frequency. This means more onshore, lumpy surface on a beach that is already exposed to the east-northeast.
Water temp rises to 24.2°C, air to around 22.7°C, and precipitation averages 2.32 mm/day. Surfing is still possible in the chest-high range on the better days, especially when a fading front delivers a rare west wind, but you will have to work harder to find clean peaks.
