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.

March at Middleton offers fairly consistent surf conditions with an average swell height of 1.5m and a solid period of 12.7s, indicating powerful, well-organized waves. The dominant swell direction is SSW, accounting for the majority of waves, especially in the 1-2.5m range, making it the primary source for quality rides. South and SW swells also contribute, though less frequently. Wind conditions are less favorable, with only 17% of the time providing ideal offshore or light winds for surfing. The predominant winds come from the S to SSE at moderate speeds (10-30kph), which can create onshore chop, particularly with stronger SE-SSE winds. However, when winds align from the NW or W, they offer cleaner conditions. Overall, March delivers decent waves with a mix of size and power, but surfers should watch for wind direction to maximize session quality.
