Conditions at Jacksonville Beach in April
April: Inconsistent In-Between Swell
By April the seasonal engine downshifts noticeably. Average wave heights fall to 0.5m (1.5ft), the period drops to 6.5s, and the ideal wind window shrinks to just 11% of the time. The swell direction table is now dominated by E (23.8%) and ESE (23.0%)-both largely local windswell rather than true groundswell-and while the ENE (13.9%) and NE (10.6%) sectors remain present, they deliver fewer organized waves. Most days will offer groveling waist-high or smaller surf, with only isolated 1-1.5m (3-5ft) peaks from lingering NE groundswell. Air temperatures warm to 20.4°C (69°F), water reaches 22.0°C (72°F), and onshore afternoon winds become more regular. April is an early-season grovel month; keep expectations low and the longboard handy.
