Port Mary - surf spot statistics

Port Mary offers the most consistent and favorable surfing conditions during the winter months, particularly from December through February. During this period, ground swell dominates (77–81%), providing powerful, well-organized waves with mean swell heights ranging from 2.5 to 2.7 meters—ideal for experienced surfers. However, wind conditions are less favorable, with bad onshore winds occurring 79–84% of the time, which can create choppy surf if not timed properly. The shoulder months of November and March still deliver solid ground swell (65–67%) and slightly better wind windows compared to peak winter. Spring (April–May) and fall (October) present a mix of ground and wind swells, with diminishing swell size (1.5–2.3m) but marginally improved wind conditions. Summer (June–September) is the least reliable season, with small, wind-driven swells (1.2–1.8m) and frequent poor winds, making it suitable only for beginners or longboarders on rare clean days. For quality waves, target December–February when ground swells are biggest and most consistent, though patience is needed for favorable winds.

February at Port Mary offers solid surf conditions with an average swell height of 2.5m and a healthy 12.3s period, indicating well-formed, powerful waves. The dominant swell directions are WSW, SW, and S, contributing to the majority of rideable waves, particularly in the 1.5m–2.5m range. These swells are clean and organized, with WSW swells being the most frequent and sizable (peaking at 8.33% in the 2–2.5m range). Wind conditions are less consistent, with only 21% of days providing ideal offshore or light winds—most frequently from the NE, ENE, or E, which can groom the swell. However, stronger onshore winds (20–30kph+) from the SE to SSW occur frequently, potentially creating choppy conditions. Advanced surfers will find the best sessions during WSW swells paired with NE winds, offering the cleanest and most powerful waves. Smaller days (1–1.5m) are less common but provide more manageable conditions for intermediate riders. Wind swell from the W or NW is minimal, so most energy comes from groundswells. Overall, February delivers punchy, mid-sized waves with occasional excellent days when wind and swell align.
