Conditions at Cadiz in December
December: Peak Size and Peak Quality
December is the statistical peak of the Cadiz surf calendar. The average swell height climbs to 5-6ft (1.6m), the highest of the year, and the period remains a powerful 11.0 seconds. WNW leads with 30.5 per cent, W contributes 15.9 per cent, NW 11.3 per cent and WSW 5.5 per cent, producing the best combination of size and consistency. The swell tables show healthy amounts of 3-6ft (1-1.8m) groundswell, with the chance of overhead-plus on the stronger WNW/W pulses, making this the month when Cadiz's west-facing sandbars show their true potential.
Winter wind patterns are also in Cadiz's favor. Ideal surfing windows peak at 39 per cent, helped by frequent E/ESE flow and lighter mornings before the westerly sea breeze fills in. Water temp drops to 16.1°C, air averages 13.8°C and precipitation reaches its annual high of 3.20mm/day, but the rain is usually tied to the same Atlantic fronts that generate the best swell. December is the month to plan your trip around.
