Conditions at Meron in December
December: Winter Solstice Swell
December is basically a preview of January. The average swell height reaches 5.5ft (1.7m), the period stretches to 12.3s, and the North Atlantic delivers storm after storm into the Bay of Biscay. NW (39.0%), NNW (17.9%) and WNW (14.8%) combine for more than 70% of the swell energy, and the 3-8ft (0.9-2.4m) range is fully loaded. This is proper winter surf - heavier, more powerful and capable of holding size.
It is also the cleanest month of the year for wind: ideal offshore flow is present 61% of the time, the highest of any month. S winds lead at 14.3%, with strong support from SSW (8.1%), SW (7.9%) and WSW (9.3%). Water temperature drops to 13.9°C and air averages 9.8°C, so winter rubber is essential. If you get a December day with offshore S/SW wind and a solid NW groundswell, Meron is as good as it gets.
