Conditions at Abrolhos Islands in November

November: The Pre-Summer Slide

November marks a clear step down in consistency as the Southern Ocean storm track begins to retreat southward. Average swell height slips to 2.3m (7.5ft) and the average period drops to 12.0s. The direction shifts back toward the southwest-south window, with SSW at 33.4%, SW at 20.1%, and S at 10.0%. There is still swell around, but it lacks the raw power and organisation of the winter months.

Wind quality erodes quickly. S winds dominate at 32.3%, SSE at 23.1%, and SSW at 13.5%, producing choppy, wind-affected surf on the southeast-facing reefs. Ideal offshore wind falls to just 5% of the time, meaning clean sessions are a rare commodity. Occasional dawn patrols can still score lined-up waves before the onshore flow builds. Water temperature warms to 21.0°C, air averages 19.8°C, and rainfall is low at 0.29 mm/day.
