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.

February at Middleton offers consistent surf with an average swell height of 1.4m and a solid period of 12.1s, indicating powerful, well-spaced waves. The dominant swell direction is from the SSW, providing the best conditions—accounting for over 80% of waves between 0.5m and 2.5m, with a significant portion in the 1-1.5m and 1.5-2m ranges. Larger sets (2-2.5m+) are less frequent but occur often enough to challenge advanced surfers. Wind conditions are less favorable, with only 14% of winds being ideal (typically light offshore or glassy). Winds from the SE-SSW dominate, often blowing at 10-30kph, which can create choppy or cross-shore conditions. Expect rideable waves most days, but early mornings or rare wind shifts will offer the cleanest sessions. Overall, it’s a reliable month for intermediate to advanced surfers, though patience with wind is key.
