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.

July at Middleton delivers consistent surf with an average swell height of 1.6m and a solid period of 13.3s, ensuring well-organized waves. The majority of the swell comes from the south and southwest (SSW, SW), with SSW swells making up the largest share (16.76% at 0.5-1m, 26.22% at 1-1.5m, and 15.58% at 1.5-2m), offering clean, powerful lines. Swell direction is favorable, with minimal onshore interference, though larger sets (~2-2.5m) are less frequent. Wind conditions are workable, with offshore or light winds occurring 31% of the time—ideal for surfing. However, winds can swing W/NW (common in winter), bringing occasional onshore chop, especially at higher speeds (20-30kph+). Expect a mix of mid-sized, long-period swells with occasional punchy peaks, making it a reliable month for intermediate to advanced surfers. Watch for wind shifts, but overall, solid waves dominate.
