Conditions at Mira in May
May: Late Spring Grovels and Glassy Dawn Windows
May is the gateway to summer's small-wave season. The average wave height eases to 5.5ft (1.7m) and the period is just 9.9s - more of a windswell-to-groundswell mix than true winter power. NW (31.7 percent) and NNW (22.6 percent) swells dominate, with WNW (21.8 percent) still contributing, but the energy is noticeably weaker and less organized. Daily wind is the bigger issue: NNW winds blow 33.4 percent of the time, reinforced by NW at 11.2 percent, and the ideal-wind number drops to 21 percent. That said, periodic east winds can still groom the surface, and water warms to 16.2C (61F) while air temps average a pleasant 16.4C (62F). If you time an E/SE day around a fading NW swell, there are fun, rippable waves to be found - just do not expect the beach to fire.
