May: Super-Solid Groundswell and a Hopeful Wind Shift
May marks the approach of summer in the eastern Pacific, and the swell data reflect it. The average wave height is 1.4m (4.6ft), with an impressive 14.2s period - the peak of the annual period cycle. The SSW direction explodes to 85.0% of the wave rose, with S (3.3%) and SW (10.7%) rounding it out. Almost 30% of the month sees 1.5-2m (4.9-6.6ft) plus, and a small but significant 2.5% reaches the 2-2.5m (6.6-8.2ft) class from the SSW. This is powerful, long-period Southern Hemisphere-style energy arriving right on the west-facing reef.
Wind is still the weak link. Ideal offshore conditions sit at only 12%. The wind rose is dominated by W (21.2%), WNW (20.3%), WSW (15.2%) and NW (11.1%), producing frequent afternoon sea-breeze chop. Still, there are signs of the summer breeze regime: ESE and SE winds begin to appear and the mornings become more workable. Water temperature climbs to 28.9°C, air averages 26.8°C, and rainfall increases slightly to 0.91mm/day as tropical moisture begins to build. May is a swell-rich month that demands patience.
