Conditions at Andora in December
December: Peak Reliability in the Deep Winter
December is the closest Andora gets to a reliable surf month. Average swell height is around 2ft (0.6m), period is 5.7s, and the ideal surfing percentage tops out at 17 percent alongside January. Swell directions are spread between SSW (24.1 percent), SW (21.6 percent) and a secondary NE/NNE arm at 21.5 percent born from cold northerly outbreaks over the Ligurian Sea. The southern component is the one to watch, because it pushes straight into the beach's SSE exposure, while SW swell wraps in with a little more west in it. The wind regime is the cleanest of the year: NNW blows 36.3 percent of the time and N another 12.1 percent, producing classic offshore mornings with the mountains behind Andora sheltering the bay from the worst land wind. When a Genoa low gets going, the combination of 3-5ft (1-1.5m) SSW swell and offshore NNW wind creates the best sessions of the season. Air temperature averages 7.4°C, water temperature 15.1°C, and rainfall is moderate at 2.40mm per day; a winter hood and boots are required, but the reward is the most consistent surf on the calendar.
