May: The Winter Conveyor Belt Locks In
May is the real start of the best surf season at Mancora. Average swell height jumps to 6ft (1.8m), period stays at 14.1 seconds, and the SSW direction dominates with a massive 88% of all swell energy. The height distribution is beautifully skewed: 58% in the 5-6.5ft (1.5-2m) range and 22% in the 6-8ft (2-2.5m) range. This is powerful, long-period, organized groundswell, exactly what a surf break needs for shape and holding power.
Wind quality improves dramatically. Ideal offshore winds now occur 70% of the time, with SSW and SW winds together accounting for 49% of the wind rose and WSW adding another 17%. Speeds are mostly in that sweet 10-20kph range, grooming the swell and keeping the surface clean. Dry-season conditions arrive: precipitation falls to 0.41 mm/day and water temperature cools to 21.6°C. If you want maximum waves per session, May is the month to start watching the forecast.
