Conditions at Costa Nova in November
November: Storm Track Re-Engaged
November is another prime month for serious surf at Costa Nova. Average swell height builds to 2.2m (7ft) with a solid 11.9s period, and the direction spread continues to favour the W-NW quadrant: NW (23.6 per cent), WNW (18.0 per cent) and W (6.5 per cent) are the headline act, with WSW (2.9 per cent) adding a touch of south in the mix. The bigger picture is a North Atlantic storm track firing on all cylinders, so expect pumping, powerful waves, especially when low pressures stall or deepen west of Portugal.
Offshore wind reliability remains strong at 46 per cent, with the wind rose showing a healthy share of E (8.7 per cent), ENE (6.7 per cent), ESE (6.2 per cent) and SE (6.4 per cent). When the wind stays offshore, Costa Nova's sandbars hold up extremely well on 10-14s groundswell. Water temperature drops to 16.0°C, air averages 13.3°C, and precipitation is at its highest (4.48mm/day), so the surf comes with rain, cold fronts and changing winds, but also some of the most consistent quality of the year.
