Winter is in full swing. Average height jumps to 2.8m (9.2ft) with a period of 12.4s. The Southern Ocean storm belt is now firing directly into the South Atlantic, producing pulsing, long-period SW and WSW groundswell - SW at 19.2%, WSW at 10.9%, SSW at 8.3%, and W at 2.9%. This is heavy, powerful surf that will light up Kalk Bay when the wind cooperates. The big change is the wind: NNW dominates at 24.8%, NW at 12.1%, and WNW at 7.0%, giving ideal conditions 22% of the time. With average air temp 12.6°C, precipitation 4.14mm/day, and water temp 15.3°C, expect wintry, stormy days on the Cape Peninsula.
