April: The Transition To Consistency
April delivers a major step toward winter. The average swell height reaches 2.2m (7ft), the average period jumps to 11.8s, and ideal winds improve to 45% of the time. The wind rose shows the E/ESE/SE onshore flow backing off to around 21% while WSW (12.7%) and W (13.6%) winds become the most frequent directions. Swell directions remain SSW-heavy (30.0%), but SW (15.4%) and S (15.8%) also supply plenty of energy in the crucial 1.5-2.5m range. This is the month when long-period Southern Ocean groundswell becomes the main storyline, and the east-facing bay benefits from refraction around the headlands. Air temps ease to 17.6°C and water temps drop to 17.7°C, so summer boardshorts give way to 3/2 or 4/3mm rubber. April is a strong fair-season month, and the morning wind often blows offshore, setting up crisp, hollow lines.
