Conditions at Banzai in April
April: Spring South Swell and Fickle Flow
April delivers some of the best swell directions of the year, but the wind is the wildcard. Average wave height is around 2.5ft (0.7m), period 5.0s, and ideal wind only 17%. S swell is the giant at 16.0%, with SSE at 14.8%, WSW at 14.2%, and SW at 13.3% - a great setup for Banzai. Yet the wind rose shows SSE (9.8%) and SE (9.2%) now challenging the offshore flow; NNE and NE have weakened to 8.4% and 6.9%, respectively. Expect clean conditions in the early morning before the thermal breeze builds, and bumpy, cross-affected surf by afternoon. Rain averages 2.00mm/day and water temp warms to 15.7°C, making a 4/3 wetsuit more comfortable. April is worth watching whenever a late-season low-pressure system parks itself over the Tyrrhenian.
