Conditions at Murtosa in December
December: Peak Season Locked In
December is arguably the most reliable month of the year for good surf at Murtosa. The average swell height is 2.5m (8.2ft), the average period is 12.5s, and the ideal-window frequency hits 50%-the highest of any month. Swell directions are perfect for a WNW-facing beach: NW 19.8%, WNW 18.5%, W 7.8% and WSW 3.6%, with most waves in the 1.5-2.5m (5-8.2ft) range and a healthy chunk of over-2.5m (over 8.2ft) sets. What really separates December is the wind. Offshore E flow is the single standout direction at 13.1%, and the full E/ENE/ESE/SE quadrant totals roughly 35% of all wind observations-an uncommon gift on this coast. With air temperatures around 11.1°C, precipitation at 3.99 mm/day and water temperature down to 14.1°C, conditions are cold and raw, but when those big WNW groundswells line up under offshore easterly winds, Murtosa can be absolutely firing.
