Conditions at Rottnest Island in November
November: Summer Pattern Locks In
November marks the arrival of the summer surf regime. Average swell height drops to 6-7ft (2.0m) and the period shortens to 12.1s, with SW (48.2%) and SSW (19.8%) again dominating the wave rose. The wind distribution shifts decisively back to onshore: S winds (17.7%) and SSW winds (22.7%) combine for over 40%, and southeasterly through southerly flow becomes the daily rhythm. Ideal surf conditions fall to just 5%, and the offshore N/NNW quadrant nearly disappears. The water is still cool enough at 19.8°C to need a spring suit, air temperatures are warming to 19.2°C, and rainfall is low at 0.91 mm/day. Most days offer bumpy, wind-affected surf with 6ft (2.0m) of swell, but occasional late-season S/SW pulses and a rare N/NW breeze can still create playful, rippable waves on the south-facing reefs, especially before the seabreeze kicks in.
