Conditions at Big Rock in April
April: Southerly Swell and More Offshore Windows
April is a transitional month with a clear shift toward southerly energy. SSE swell dominates at 65.6% of the wave rose, followed by SE at 25.8%, meaning Big Rock is not seeing its favorite NE-ESE strike window very often. Still, wave heights are workable: most surf falls into the 0.5-1m (1.5-3.3ft) range, with about 17% in the 3-5ft (1-1.5m) category and an average period of 8.1s. The wind regime improves further, with ideal offshore flow up to 36% of the time, and SSW/SW winds becoming a regular part of the pattern. This means more clean, groomed sessions than in March, especially in the morning before the sea breeze kicks in. Water temp climbs to 29.7°C and air averages 30.6°C, so it is full-on tropical. April surf is not powerful, but it is a big step up in quality from the winter months.
