Conditions at Barra de la Cruz in May
May: Peak Period and Peak Frustration
May often delivers the highest average wave period of the year at 14.1s, edging toward the upper end of the powerful long-period range. Average height is 5.2ft (1.6m), and the swell direction is overwhelmingly favorable: SSW accounts for 70%, S for 15%, and SW for 8.2% - over 93% from the south/southwest. A large portion of the observations fall in the 5-8ft (1.5-2.4m) range, so this is a serious groundswell month. The problem is wind. Ideal offshore flow is just 47%, with WSW, SW, and W winds dominating much of the daily cycle. Rain begins to ramp up to 1.57mm/day, and water temp reaches 29.9°C, making for warm, humid, occasionally stormy conditions. Look for early glass-offs and the occasional longer-period pulse between tropical waves.
