State's Avenue seasonal overview
State's Avenue generally experiences a mix of wind swells and ground swells throughout the year, with wind swells dominating the swell regime. The best months for surfing tend to be late summer and early fall, particularly September, which offers the highest percentage of ground swells (24%) and relatively better wind conditions (24% good winds). Swell size also peaks slightly in March and September (0.9m mean), though the difference is marginal compared to other months. Wind conditions remain challenging year-round, with the highest probability of favorable winds occurring from May to August (21-22%). However, even in these months, bad wind conditions still prevail most of the time. Ground swells are rare overall, only exceeding 10% in January, March, August, September, October, and December. If prioritizing quality over consistency, September stands out due to the higher ground swell contribution, slightly larger waves, and marginally better wind stats. Most other months see predominantly wind swells with small to average wave heights and frequent onshore winds, making conditions inconsistent and often suboptimal for high-performance surfing. Early fall provides the best balance, while winter and spring tend to be wind-affected and less reliable.
