April: Long-Period Power Arrives
April is a turning point on the Central American Pacific coast. The average wave height jumps to 3.9ft (1.2m), and the average period hits 14.0s-one of the two highest monthly averages of the year. The distribution is extraordinary: a full 75.4% of all waves are SSW with 3-5ft (1-1.5m) heights, plus 6.0% in the 5-6.5ft (1.5-2m) range. That is an incredibly high percentage of clean, liquid, long-period swell. The downside is the arrival of the wet season; precipitation jumps to 2.99mm/day, and ideal wind drops to 21%. Still, with water at 29.4°C, this is the month when the bathwater meets the power and the sandbars start looking like a proper setup.
