Middleton - surf spot statistics

Middleton, Australia, offers consistent surf conditions year-round, with ground swell dominating over wind swell in every month. The best time to surf here is during the autumn and winter months (April to September), when ground swell percentages peak above 90% and mean swell sizes range from 1.5m to 1.7m. Wind conditions improve significantly during this period, with good wind days occurring 29-34% of the time—far more favorable than summer months, where onshore winds are prevalent (bad wind conditions above 80% from December to March). The largest swells arrive from May to September, with August and September seeing the biggest waves (1.7m). While summer (December-February) still provides rideable swells (1.4m), the high frequency of poor wind conditions (over 85%) makes it less ideal. March and October serve as transitional months, offering decent ground swell but less reliable winds. For surfers seeking optimal conditions—solid, clean waves with minimal wind interference—the window from April to September is the prime season at Middleton.

May at Middleton offers decent surfing conditions with an average swell height of 1.5m and a strong swell period of 13.4s, indicating well-organized and powerful waves. The dominant swell direction is from the SSW, contributing to the majority of rideable waves, particularly in the 1-2.5m range. SSW swells account for over 50% of the surfable conditions, making it the most reliable direction. Wind conditions are favorable for surfing 34% of the time, with lighter offshore or cross-shore winds predominantly from the NE to SE, helping to keep the waves clean. However, stronger onshore winds from the W to SW can occasionally disrupt conditions, especially at higher speeds. Overall, May delivers consistent, mid-sized waves with good shape, though wind quality can be variable. Experienced surfers will find the best windows early in the day when winds are lighter.
