June: Heavy Winter Swell and a Battle with the Wind

June is where Smiths starts to feel serious. Average swell height jumps to 8-9ft (2.6m) with a 12.9-second period, and the swell spectrum shows a strong WSW/W component, with NW/NNW also appearing more than in summer. These are long-period, high-latitude Southern Ocean swells. For a NW-facing beach, this is the season of consequence, but also of complication.

The complication is wind. The frontal belt is now directly over the region and the wind rose is dominated by W, WSW, WNW and NW, with 40-50kph gusts not unusual. Ideal offshore flow collapses to 17 percent. The rare clean post-frontal morning with S/SW wind can deliver unforgettable, heavy waves, but you will need to be selective. Air temperature drops to 17.0°C and water to 19.2°C, and 3.88mm/day of rain keeps the region green.
