Conditions at Cables in December
December: Early Summer Lull with Occasional SW Gems
December settles into the summer pattern at Cables. The average swell height is 1.9m (6ft), the period is down to 11.7s, and the overall consistency fades. Swell direction is still strongly southwest, with SW at 48.1% and SSW at 28.8%, but the WSW/W window accounts for only about 5.5% combined. The 1.5-2.5m (5-8ft) bands still appear, yet the intervals are shorter and less organized than a few months earlier.
Wind quality is the main limitation. Ideal offshore flow is just 25%, and the wind rose is dominated by SSW (25.4%), S (14.3%) and SW (10.8%). Those directions keep the surface bumpy for much of the day. Early morning is often the only clean window before the seabreeze kicks in. On the bright side, water temperature is back up to 21.0°C, air averages 21.3°C and rainfall is minimal at 0.34mm/day. Keep an eye on the charts for a tropical or mid-latitude disturbance that sends a fresh SW groundswell - when it aligns with an ESE/SE offshore, December can still throw out a few gems.
