Conditions at Pipeline in April
April: The Shift to Trade Swell Begins
April is a transition month. Average surf height drops to 7.2ft (2.2m) and average period slides to 10.3s, signaling weaker, shorter-period energy. The swell rose now points strongly toward ENE at 24.2% and NE at 17.5%, with the ideal NNW/NW/N window shrinking to around 15% of the total. Trade winds blow from ENE and E a combined 73% of the time, while favorable south to southwest offshore wind drops to 16% of observations. On the best days, a passing winter remnant can still light up the reef, but the consistency and raw power of the season are fading. Air temperature is 23.5°C, water temperature 24.2°C, and precipitation decreases to 1.39mm/day.
