Conditions at Sopelana in January
January: Midwinter Powerhouse
January sits at the heart of Sopelana's prime surf season. The average swell checks in at 2.1m (7ft) with a solid 12.8s period, meaning the bay is regularly filled with powerful, long-period groundswell. The NW and WNW directions combine for over half of the total swell, and when you add the NNW and N pulses, close to two-thirds of the energy arrives from the preferred exposure for this NW-facing beach. Many of those waves fall in the 1.5-2.5m (5-8ft) range, so expect pumping, heavy waves on the better sandbars. The offshore wind window is excellent: S and SSW winds blow nearly 25% of the time, and the overall ideal wind score sits at 31%. Onshore W and WNW winds still fire during cold fronts, so patience and a sharp eye on the forecast are essential. With air temperatures ranging from 2°C to 20°C and sea surface water around 13.1°C, January surf is a cold-water mission - but the reward is some of the most powerful, hollow waves of the year.
