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.

December at Middleton offers decent surfing conditions, though with some variability in swell and wind. The average swell height is 1.4m with a solid 11.8s period, providing well-formed and consistent waves. The predominant swell direction is from the SSW, accounting for 32.82% of waves in the 1-1.5m range and 18.67% in the 1.5-2m range, ensuring plenty of rideable waves with good energy. However, winds are often less than ideal, with only 13% of conditions being favorable for surfing. Winds from the S to SW directions are most common, frequently blowing at 10-30kph, which can create choppy or cross-shore conditions. While the swell quality is reliable, surfers should monitor wind forecasts closely for those cleaner, glassier sessions. Overall, Middleton in December delivers fun, workable waves, but patience may be needed for optimal conditions.
