Conditions at Lagkouvardos in December
December: Peak Consistency and the Best Wind Window
December edges out January as the most consistent month of the year at Lagkouvardos. Average wave height is around 3.5ft (1.0m), average period reaches 6.5s, and the ideal offshore wind frequency peaks at 23%. The winter swell engine is running: WSW (17.5%), NW (13.9%), W (12.9%) and WNW (11.9%) combine for a strong western bias, and the 3-6ft (1-2m) size classes fill in more often than in any other month. The wind regime also improves as continental high pressure strengthens, delivering E/ENE/ESE offshore days that groom the west-facing lineup. NNW (16.5%) and NW (10.3%) remain frequent, so timing is still key. With air temperatures averaging 11.8°C, water at 18.3°C and 3.67 mm/day of rain, the trade-off is weather: the biggest swells come with cold fronts. But when the front clears and offshore wind flicks on, December is as good as it gets in Greece.
