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.

October at Middleton delivers solid surf conditions with a mean swell height of 1.6m and a favorable average period of 12.9s, ensuring consistent, well-spaced waves. The swell is predominantly from the SSW (29.86% of waves in the 1-1.5m range, 20.14% in 1.5-2m), followed by SW and S directions, providing clean, medium-sized waves ideal for intermediate to advanced surfers. Smaller swells from other directions are rare. Wind conditions are variable, with only 23% of days offering ideal offshore or light cross-shore winds, primarily from the ENE to ESE. However, moderate onshore winds (SSW to W) are more common, potentially causing chop, especially at higher speeds (20-30kph). While offshore winds are less frequent, the long-period SSW swells still create quality waves when winds align. Expect a mix of clean days and choppier sessions, but overall, October provides reliable surf with a good balance of size and shape.
