Conditions at Piha in July
July: Midwinter Maximum Intensity
July is the heart of the New Zealand winter, and Piha is at its most powerful. Average swell holds at 6ft (1.9m) with a 12.8s period, and the dominant SW/WSW direction means constant exposure to Southern Ocean storm swell. This is the month with the largest share of heavier, 5-8ft (1.5-2.5m) surf, and the 8ft+ (2.5m+) mark is increasingly breached. The wind remains the limiting factor: only 22% ideal offshore conditions, as westerly fronts and low-pressure systems roll across the Tasman. Water temperature hits its winter low of 14.0°C, air temps average 12.8°C, and the rain is persistent. It is a serious, charging month for experienced surfers only.
