Conditions at Jacksonville Beach in May
May: Sea Breeze and Micro Windswell
Late spring at Jacksonville Beach is a lesson in trade-wind micro-swell. The average wave height is 0.5m (1.5ft), the period is a junky 6.3s, and the wind is ideal for surfing only 7% of the time. The swell direction is almost entirely from ESE (31.1%) and E (26.4%), a signature of the onshore trade-wind/sea-breeze regime pumping short-period windswell into the beach. ENE and NE contributions drop quickly, and nearly all waves are below 1m (3ft), with the vast majority in the micro category. Water temperature climbs to 25.1°C (77°F), air temperatures average 24.0°C (75°F), and afternoon showers help produce 2.63mm/day of rain. Longboards and foam boards are the tools of choice unless a rogue tropical swell sneaks in.
