December: The Summer Lull Sets In
December brings high summer back to Barra. Average swell height drops to 3.3ft (1.0m) and period falls to 9.7s, with the bulk of waves (57%) in the 2-3ft (0.5-1m) range. SSE (32.2%) and S (30.1%) still show up, but the power is missing. Ideal wind is 47%, so there are some clean mornings, but the E/ENE trade wind and sea breeze limit the good windows. Air temp is 24.7°C, precipitation is high at 7.05 mm/day and water temp is 21.7°C. It is summer-break material: small, fun and often soft, with the occasional swell lining up after a summer storm lifts.
