Conditions at Manazillo Bay in May
May: Big Southern Groundswell, Marginal Winds
May delivers the first serious southern-hemisphere groundswell of the year, with the average height climbing to 1.5m and periods maxing out at 14.2s. It is also the most directionally biased month, with 76 percent of the swell arriving from the SSW. While that energy is long-period and powerful, it is not the most efficient angle for a west-facing beach, and the heavy WSW-SW onshore winds keep the ideal-wind score at just 19 percent. When a dawn window aligns, expect 3-5ft surf with 5-6.5ft bombs mixed in; by midday, wind chop tends to win. Air temperature climbs to 27.6°C and water remains toasty at 28.8°C.
