Conditions at Andran in December
December: Winter's Building Block
December may be the peak consistency month at Andran. Average swell height is 1.8m (6ft) with a powerful 12.4s period, and the wind is ideal an impressive 45% of the time. NW remains the main swell source at 39% of recorded swell, but WNW (16%) and NNW (16%) are also strong, creating a broad, high-energy window. Swell heights in the 1.5-2.5m (5-8ft) range are common, and the longer periods make the beach feel much bigger than the raw numbers suggest.
From a meteorological standpoint, the Atlantic is at its most active and it shows in the wind data - S/SSW/SW/WSW offshore flow is abundant, especially in the 10-20kph range. This is one of the best months for finding clean, glassy conditions with proper groundswell. Water temperature is 14.2°C, air averages 10.3°C, and precipitation is high at 3.46mm/day - winter surf in Spain doesn't get much better than this.
