Conditions at Ilha dos Lobos in December
December: Summer Returns
December marks the official return of the summer trade-wind regime. Average period falls back to 8.2s, average heights settle at 1.5m (5ft), and ideal wind dips to 26%. The swell is overwhelmingly E/ENE windswell -- ENE (22.1%), E (22.8%), ESE (17.0%) -- with SE and SSE contributing a secondary pulse. Waves are generally in the fun-sized 3-5ft (1-1.5m) range with occasional 5-6ft (1.5-2m) sets.
Trades from NE (19.4%) and ENE (16.0%) dominate the wind rose, so clean surfaces are the exception rather than the rule. Yet the warmer days and water temp of 22.1°C make it a pleasant season for longboarding or small-wave cruising. A decaying cold front can still bring a brief offshore W/NW flow and turn the grovel into something more interesting, but December is ultimately a month to be patient for the natural wind.
