Conditions at Costa Navarino in December
December: Peak Season Arrives
December is arguably the best month of the year at Costa Navarino. The average swell height holds at 3ft (1m), the period sits at 6.5s, and ideal offshore wind peaks at 37% - the highest of the annual cycle. The swell rose is the most favorable of any month, with the SSW-SW-WSW-W window contributing 47% of all observations. WSW is the clear stand-out at 17.5%, and W at 12.9% and SW at 10.6% add serious depth. This is the month where you are most likely to find clean, head-high waves wrapping down the beach during a December storm.
The wind climate is also in prime winter mode. NNE, NE, ENE and E combine to give that offshore, glassy texture that transforms an average beach break into something worth calling in sick for. It is cooler - air temps average 11.8°C and water drops to 18.3°C - and wet at 3.67 mm/day, but the Mediterranean winter payoff is exactly this: the waves are as good as they are going to get. Get your 4/3 ready and pick your windows carefully.
