December: Winter Grooves and Offshore Surprises
December locks in the winter pattern at Mekakoz. Average swell heights hold at a meaty 6.6ft (2.0m) with a long 12.4s period - the North Atlantic is at full power. The wave rose points squarely at the beach: NW contributes 29.6% of the energy, WNW 20.4%, NNW 10.1%, with the W direction adding some west-northwest variety. Perhaps the most interesting feature in December is the wind. The offshore quadrant (S, SSW, SW, WSW) accounts for a season-leading 39.4% of all wind observations, giving Mekakoz its best chance of a clean, groomed, powerful winter wave. SSW alone is a hearty 16.5%, thanks to the frequent succession of Atlantic lows that drag southerly flow ahead of their fronts. That means when the swell hits, the wind is often blowing offshore - a rare and prized combination. With air temperatures just 10.8°C and the sea at 14.0°C, it's cold, and precipitation is high. But these are the days you dream about: heavy, hollow, long-hold-down waves at Mekakoz, with the winter Atlantic roaring right behind you.
