Conditions at Chatarra in December
December: Back to the Winter Root
December closes the year with Chatarra's most winter-like profile. Average surf height is 2-3ft (0.6-0.9m), the average period rebounds to 6.2s, and the ENE contribution jumps to 11.0%, the highest of the year. Pure E is still the leader at 53.9%, but the mix of ENE with a 6.2s period gives the break a bit more push and makes the lineup slightly more organised than in summer. This is the start of the season when a properly tracking North Atlantic low can actually light up the north-facing corners.
Winds, however, are the catch. Ideal offshore wind falls to 20%, the lowest of the year, while E and ENE combine for nearly 60% of all wind observations. That means you have to be selective and wait for cold-front passages to swing the breeze offshore. Air drops to 25.5°C and water to 27.4°C, with rainfall at 2.71mm/day. If you can marry a north swell with a southerly wind, December has the potential to deliver the best session you will find at Chatarra all year.
