Conditions at Artiglieria in April
April: Spring Grovel Mode
April is when the surf dials down noticeably. The average swell height is 2ft (0.6m) but the average period drops to 5.3s, signalling a shift from groundswell to windswell. The direction remains good - WSW (24.2%), W (22.6%), SSW (12.9%) and SW (11.9%) make up over 70% of the total - but the energy is increasingly local and short-period. Offshore wind frequency falls to 12%, and the thermal-driven WNW/NW flow starts to become more common through the afternoon. This is longboard and small-wave season in a 4/3 wetsuit; water temperature has climbed to 15.6°C and air averages 13.1°C. Occasionally a late spring low over the Tyrrhenian produces a clean 3-4ft (0.9-1.2m) window, but don't expect power or consistency.
