July: Winter Swell Still Pumping
July holds onto winter's energy. S/SSW/SW swell remains potent at about 23% of the spectrum, while ENE and E trade-wind swell also rebuilds - so the average height holds at 1.8m (6ft). The mean period slips only slightly to 9.4s, meaning waves still have real push out of the south. Perfect offshore windows drop a touch to 31%, but NNE flow remains the dominant wind, blowing 26.6% of the time. Frontal onshore S/SW winds are present around 34%, so make sure to time the post-frontal clearing. Water temperature falls to its annual low near 17.3°C; air temp averages 16.7°C. July rewards patience with solid, consistent winter surf.
