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.

January at Middleton offers fairly consistent surf conditions with an average swell height of 1.4m and a solid 11.9s period, indicating clean and well-spaced waves. The majority of swells come from the SSW direction (74.57% between 0.5m and 2.5m), with the most productive range being 1-1.5m (35.54%) and 1.5-2m (19.06%). Larger swells (2-2.5m) still occur 5.33% of the time, providing occasional punchy sets. Swell consistency is decent, with the S and SW directions contributing smaller but still surfable waves. Wind conditions are less favorable, with only 13% of the time being ideal (typically light offshore or cross-shore from the NW-NNE quadrant). The dominant winds are S-SSE at 10-30kph (often onshore), which can create choppy conditions. However, early mornings or days with lighter SE/SSE winds may provide cleaner surfaces. Overall, expect rideable waves most days, but wind management is key—target sessions when winds are light or northerly for the best shape.
