Conditions at The Island in July
July: Midwinter Powerhouse
July holds the winter line with 7ft (2.1m) average swell and a 10.8s period. S swell remains the dominant source at 15.8%, with SSE (12.9%) and SE (10.8%) keeping the direction mix southern-leaning. E/ESE energy also appears at 7.2% and 8.4%, but those are secondary; the Island is all about the long-period S pulses that arrive between cold fronts. Wind is ideal 45% of the time - the lowest of the winter months - as SW (12.1%) and SSW (9.0%) compete with NW (10.9%), NNW (11.1%), and WNW (13.1%). Patience is essential: the swell is there, but the wind windows are narrower. Expect water temps around 13.8°C, air averaging 9.4°C, and 4.01mm/day of rain. When the NW wind finally cleans up the S swell, it's all-time.
