Polzeath • Surf Spot Statistics

Best Surf Season (October - March)

Polzeath's west-northwest exposure lights up when the North Atlantic storm track shifts south and the Icelandic Low deepens through autumn and winter. Negative phases of the NAO often push the jet stream further south, directing a conveyor belt of low-pressure systems at the UK and ensuring a steady supply of powerful groundswell. Average surf heights run 5-7ft (1.5-2.2m) with periods commonly in the powerful 10-12s band, and the dominant west to north-west swell windows are exactly what this stretch of North Cornwall needs. Offshore winds from the east through southeast occur around 23% of the time, often in the wake of passing cold fronts or under slow-moving continental highs, delivering clean, hollow lines across the beach. This is the money window for serious wave riding.

Fair Surf Season (April and September)

The shoulder months offer a transition between summer lull and winter power. April and September still produce rideable W and WSW swells in the 3-5ft (1-1.5m) range with periods around 10s, and the slightly higher percentage of offshore wind days keeps the surface smoother. It may not have the consistency of winter, but the lighter airs and more settled weather create good opportunities for longboarders and grovelers when the swell fills in.

Low Surf Season (May - August)

Summer sees the Azores High build across the UK, suppressing the North Atlantic low pressure systems and shrinking average surf heights down to 3-4ft (1-1.2m). Periods drop to 8-9s, so the waves become softer and less organised, while the dominant west and north-west winds are increasingly onshore and bumpy. This is the flat-to-small window, though occasional summer groundswell from distant Atlantic lows can still produce fun, rippable surf.
