Conditions at Gas Bay in June
June: Deep Winter Power
June is when Gas Bay starts to feel serious. The average swell height climbs to 2.6m (8.5ft) with a long 12.9s period, and the Southern Ocean storm track is firing on all cylinders. The swell direction becomes more westerly: SW delivers 20.4%, WSW 14.5%, W 5.4% and WNW 2.6%, alongside a few northwesterly contributions. More of these waves are solid 2-2.5m (6.5-8ft) plus, with occasional 2.5m+ (8ft+) XXL pulses. The catch is wind. June sees a big increase in W (9.9%), WSW (9.2%), WNW (9.4%) and NW (7.7%) flow, much of it onshore at Gas Bay. Ideal NE offshore flow drops back to 22%, so the precious windows are usually short and tied to passing cold fronts and transient highs. Water temperature cools to 19.0°C, air temps average 15.6°C and rainfall is high at 3.98mm/day. It gets heavy, stormy and a bit raw, but the clean days are genuinely memorable.
