Conditions at Porzcarn in November
November: Storm Track Ignites
November sees the winter storm machine begin to fire on all cylinders. Average swell height jumps to 6ft (1.9m), period sits at 10.9s, and the Atlantic sends a much more aggressive mix of WNW (19.2%), W (22.5%) and WSW (11.9%) swell toward Porzcarn. The heights are substantial: many readings fall in the 5-8ft (1.5-2.5m) range, producing powerful waves on the exposed west-north-west break. Onshore winds, however, remain the main antagonist. The WSW-W-WNW-NW quadrant blows around 32% of the time, and the ideal offshore fraction drops to just 15%, so November is often a fight between size and shape. When high pressure nudges in from the east, though, the beach cleans up and the period is long enough to deliver proper long-period waves. Expect cooler air (10.9°C), dropping water temps (14.0°C) and increasing rain (3.56 mm/day) as winter takes hold.
