Conditions at Rosie's Bay in July
July: Mid-Summer Flatness
July is the absolute low point of the surf calendar at Rosie's Bay. The average swell height bottoms out at a modest 1.2m (3.9ft) with an 11.4s period, and the majority of waves are in the 0.5-1.5m (1.6-5ft) range - small, fun-sized at best. The direction mix is still west-based, with W (39.8%), WSW (30.6%), and SW (13.3%) doing almost all the work, but the lack of size and energy is the story. Onshore winds are brutal: WNW blows 28.8% of the time, W 16.8%, and NW 15.7%, leaving ideal offshore wind at a mere 17% - the lowest of the year. This creates constant cross-onshore chop on the exposed bank. Air temperatures are at their warmest, 14.6°C, and water peaks at 13.3°C, but the surf is small and messy. July is for longboarders, beginners, and those content with ankle-to-waist-high waves.
