Conditions at Sandon Point in December
December: A Summer Lull
December is the holiday season lull at Sandon Point. Average swell height dips to 1.5m (4.9ft), with an 8.4s average period, so the majority of waves fall into the small-to-fun grovel range. The swell rose is dominated by ENE (17.1%), SSE (18.0%), E (13.3%), ESE (12.7%), SE (14.3%) and NE (10.5%), giving the point constant but messy energy. Ideal offshore winds drop to just 23% of the time, with NE (12.4%), NNE (11.1%), S (11.7%) and SSE (11.2%) making up a large share of the wind distribution. The few clean days come when a W/NW offshore coincides with an E/NE swell, typically in the morning. Water is warm at 20.8°C, air averages 19.7°C, precipitation is 2.42mm/day, and summer crowds add another challenge. It's a month for small-wave boards and a relaxed attitude more than epic winter perfection.
