Conditions at Port Mary in July
July: The Mid-Summer Lull
July is the absolute low point of Port Mary's surf year. The average swell bottoms out at 4.3ft (1.3m), the period is 10.2s, and ideal wind days plummet to just 20 percent-the lowest of the entire year. The good news is that swell direction is still extremely favorable, with SW and WSW providing the majority of the energy; the bad news is that most of it is small, with the bulk sitting in the 2-5ft (0.5-1.5m) range. Onshore S/SSE/SW flow becomes the dominant pattern, and Port Mary often turns fat and bumpy. Weather is mild with an average air temperature of 12.7°C, water sits at 13.2°C, and precipitation is moderate at 4.34mm/day. Chase the rare early-morning glass-off or simply enjoy a summer session on a soft-top.
