The swell mix is still SW/WSW-led, but there is more spread across SSW, W and S, keeping the window active from several angles. The wind is superb for the spot, with NE through ESE directions blowing offshore over half the month and ideal conditions 52% of the time. Air temps average 3.0°C, water sits at 6.9°C, and winter storms keep precipitation frequent.
