June: Summer Slump
June brings the heart of the summer slump to Rosie's Bay. Average swell height dips to 1.4m (4.6ft) and the period eases to 11.4s. The swell direction remains stubbornly westerly - WSW (36.8%) and W (32.3%) dominate, with SW (15.3%) and SSW (5.5%) - but the wave heights trend smaller, with a large proportion falling in the 1-1.5m (3-5ft) fun-sized range. The real issue is the wind. Ideal offshore flow bottoms out near 22%, while persistent onshore WNW winds blow 26.8% of the time, with W at 13.4% and NW at 12.3%. The combination of small swell and summer sea breeze makes the bay soft, bumpy and largely uninviting. Air temperatures average 12.5°C, water warms to 12.9°C, and precipitation is low at 2.5mm/day. If you're chasing waves, this is the time to look for a protected crutch or pray for a rare tropical-plume south swell - but Rosie's Bay is mostly a summer flatline.
