Conditions at Pine Grove in December
December: Winter Slump Begins
December is the start of the worst stretch of the year for Pine Grove. Ideal wind bottoms out at 35 percent, the lowest of any month, while average height is 2-3ft (0.8m) and period 6.2s. Swell is dominated by E (53.9 percent), with ESE at 30.1 percent and ENE at 11.0 percent. Wind directions are heavily weighted to E (34.7 percent), ENE (25.1 percent) and ESE (16.1 percent). The persistent E/ENE cross-shore and onshore flow keeps the ocean lumpy, and the weak 6.2s period means the waves rarely organize into real shoulders. Water temp remains a warm 27.4°C, air temp averages 25.5°C, and rainfall is relatively low at 2.71mm/day. You can still find sheltered corners and the odd morning glass-off, but December is a month for the longboard and low expectations.
