Conditions at Ansteys in July
July: Mid-Winter Reliability Holds
July remains a top-tier month. The average height is 5-6ft (1.7m), the period is 10.7s, and ideal wind windows are 51%. S swell still dominates at 24.6%, with SSE at 16.9% and E/ESE/SE around 12-14% each. The 6-8ft (2-2.5m) range is well represented from the S (6.4%) and SSE (1.4%), and there are occasional overhead-plus monsters from the S and SSW. Consistent cold-front activity south of the continent keeps the Southern Ocean machine cranking.
Offshore flow remains frequent, with NW and NNW directions contributing a solid slice of the wind rose. The onshore E/ESE/SE/SSE sector is at its seasonal low, around 6%, which is why the month feels so much cleaner than summer. Air temperature bottoms out near 20.0°C, water temperature sits at 21.8°C, and rainfall is still low at 1.43mm/day. A 4/3 wetsuit becomes your best friend and the sandbanks are firing with winter consistency.
