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.

June at Middleton offers consistent surf with an average swell height of 1.5m and a solid period of 13.3s, providing clean, well-spaced waves. The dominant swell directions are SSW (peaking at 23.17% in the 1-1.5m range) and SW, which means most swells align well with the break, producing quality rides. Larger swells (2m+) are rare but occur, mostly from the SSW and SW. Wind conditions are mixed, with only 33% of days offering ideal offshore winds (light ENE to E). However, winds from the N/NW quadrant are more common, often blowing 10-30kph, which can create choppy conditions. Surfers can expect frequent chest-to-head-high waves with occasional bigger sets, best on lighter wind days when swells hold shape. Winter consistency is reliable, but wind luck plays a role.
