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.

November at Middleton offers solid surfing conditions with an average swell height of 1.4m and a favorable period of 12.3s, producing clean, well-spaced waves. The dominant swell direction is from the SSW (32.15% of waves in the 1-1.5m range), followed by SW and S, ensuring consistent, rideable waves with decent energy. Smaller swells from the S and SW also contribute, often providing ideal conditions for intermediate to advanced surfers. Wind conditions are less reliable, with only 17% of days offering ideal offshore or light cross-shore winds (typically from the N to ENE). However, SE to S winds are more common (reaching 20-30kph in 5-20% of cases), which can create choppy conditions. The best sessions will come when SSW swells coincide with lighter winds—expect shoulder-high to head-high waves with good shape and occasional larger sets (2-2.5m) on strong SW swells. Pack your standard shortboard or step-up for bigger days, but expect occasional wind-affected sessions when onshore breezes pick up.
