Conditions at Pease Bay in December
December: Winter Solstice Swell
December closes the year with similar stats to November: 5ft (1.5m) average swell, 6.3s period. The N/NE/ENE quadrants contribute around 22% of the wave spectrum, with ENE and NNE both delivering pulses in the 3-6.5ft (1-2m) range. Longer-period groundswell is still not the norm, but winter solstice storms bring occasional 10s-plus swell from the N/NE quadrant that light up Pease Bay perfectly. The main risk is wind: strong WSW and W gales occur throughout the month, and offshore S/SW winds appear 13% of the time.
At SST 8.4°C and air 5.2°C, with frost possible inland, it is full winter conditions. Precipitation is frequent at 2.34 mm/day, and storm windows can be short-lived. When a high pressure ridge builds behind a front, the drop in wind speed combined with lingering N/NE swell makes for some of the best, chilliest surf of the season. December is a wildcard, but it can be excellent.
