Conditions at Mossel Bay in June
June: Mid-Winter Muscle with Onshore Issues
June is a heavy month. The average swell climbs to 7.5ft (2.3m) with a 12.2s period, and SW becomes the dominant swell direction at 28 percent, with SSW close behind at 23 percent. This is powerful, open-ocean groundswell, and the 5-8ft (1.5-2.5m) range is the main event. When Mossel Bay lines up, it can be firing and heavy.
The catch is the wind. Ideal flow bottoms out near 23 percent, matching July for the lowest of the year. Pre-frontal N/NNE/NE/NNW winds and strong W/NW flow dominate the wind rose, leaving the bay choppy and sectiony for many days. Air temperatures drop to 12.9°C, water temperature falls to 16.0°C, and precipitation is 1.05mm/day. These are serious winter waves for advanced surfers only.
