Conditions at Isla Chepillo in March
March: The Peak Trade-Wind Clean-Up
March is arguably the prettiest flat month on the calendar. Wave period climbs to 11.3s, indicating longer-period southern hemisphere energy filtering into the Gulf of Panama, and SSW swell becomes even more dominant (49.6%) with SW adding another 12.7%. Yet the average wave height is still 0.3m (1ft), and over 93% of waves are below 0.5m, leaving the southwest-facing beach with little to work with. The offshore trade wind machine remains in full swing: N and NNE directions combine for over 62% of all wind, with most observations in the 10-30kph range. This is ideal wind for Isla Chepillo, but with no wave height behind it, the result is a beautifully groomed ocean with ankle-biters too small for a real surf. Air temperatures rise to 27.5°C, rainfall is light at 0.58mm/day, and water temperature is at its coolest of the year at 24.0°C.
