Ideal wind percentages leap to 57%, and the proportion of W, WSW, SW and SSW flow in the wind rose is at its highest point in the seasonal cycle. Swell averages 3-4ft (1.1m) with an average period of 8.8s, generated by E/ESE systems and reinforced by SE pulses from the Tasman Sea. The wave faces are cleaner and the sandbar more defined; typical winter high pressure systems bring light morning offshore winds before a moderate sea breeze. Water temperature drops to 23.3°C, nights cool to around 13°C, and rainfall sits near 3.2mm/day - time to pull out the spring suit.
