Conditions at Sealion Cove in July
July: Smallest Averages and Peak Onshore Breeze
July is the absolute bottom of the surf calendar. Average heights bottom out near 1.3m (4.3ft) with a period of 10.2s. The swell is overwhelmingly small SW (32.8%) and WSW (28.8%), with most readings in the 0.5-1.5m range. There is essentially no NW-NNW component, so the cove loses its most powerful winter source. This is groveling territory - longboards and foil boards will have more fun than a shortboard.
Wind quality also hits a low point: only 32% ideal offshore flow, while WNW and NW onshore winds account for a combined 29.9%, alongside a solid W component. Air temps average 12.8°C, water reaches 13.2°C, and precipitation is moderate at 4.45mm/day. The warmest water of the summer comes with the worst summer surf - a classic trade-off in this part of the world.
