Conditions at Porto Katsiki in November
November: Prime Time on the Ionian
November is the pick of the primary season at Porto Katsiki. Average swell height builds to 3ft (0.9m) and the average period extends to 5.2s, while the S/SSW/SW corridor reaches its highest collective share of the year at 30.8% of all directional energy. This is the month when Mediterranean cyclogenesis, a negative NAO phase and cold polar air surging down the Adriatic can all combine to produce the most consistent S/SW swell windows. The NW sector remains important at 18.4%, but the balance is far healthier: WSW (10.1%), SSW (9.5%) and S (10.1%) all add usable energy. Ideal offshore wind is 14%, and while onshore flow from the south and west is common as fronts move through, the post-frontal N/NNE/NE gaps are frequent enough to reward patience. Water temperature cools to 20.5°C, air to 17.4°C, and rain is the heaviest of the autumn at 4.52mm/day. On a strong event, Porto Katsiki can see clean, punchy 3-5ft (0.9-1.5m) waves down the SSW-facing bight.
