Conditions at Florence in April
April: Swell Power Fades as the North Wind Builds
April is the classic shoulder month at Florence. Average swell heights drop to around 7.5ft (2.3m) and periods ease to 11.6s as the North Pacific storm track weakens. The dominant swell still comes from WNW (23.9%) and W (19.0%), with NW (10.3%) and WSW (9.5%) adding a broad angular spread. This broad mix keeps the beach reasonably active, but the energy turns more wind-driven and less organised, with fewer of those long-period, winter-style groundswells.
Onshore and cross-shore wind becomes the main problem. Ideal conditions drop to just 22% as NNW winds become the dominant flow, blowing 21.7% of the time and creating plenty of surface chop. S and SSW winds also remain common, so clean dawn patrols become a rare commodity. The weather turns slightly drier at 3.89 mm/day and milder with air temps near 9.8°C. Water temps edge up to 11.1°C. April can still produce great days if an east wind lines up with a departing storm, but the consistency is fading fast.
