October: Spring Swell and the Return of the Trades
October is an in-between month. The average swell height remains sturdy at 2.2m (7ft), but the period slackens to 9.8s - a sign that the swell source is becoming less organised, with more local windswell mixed into the groundswell. Directionally, S (16%) and SSE (11.9%) are most common, with healthy amounts of E (9.8%), SE (10%), and ESE (9.1%). The 1.5-2.5m (5-8ft) range still dominates, but the quality starts to suffer under the influence of the NE trades. The ideal offshore wind window drops back to 15%, matching the low summer values. The NE (22%) and ENE (16%) winds are strong and persistent, so surfable days occur mainly in the early morning or during the passing of a coastal low. Water temp is 20.9°C and air temp warms to 20.1°C, with precipitation increasing to 2.79 mm/day. September's long-period gems become rarer, but October still offers occasional excellent sessions for those who are flexible.
