Conditions at Katagai in January
January: Deep Winter Offshore Windows
January is a prime month at Katagai as the Siberian High sends repeated blasts of offshore NNW/NW wind across the coast. The wind blows from an ideal offshore quadrant 46 percent of the time, the second-highest mark of the year, and the average period sits at a solid 9.5s. Average surf height runs near 4ft (1.2m), with the largest waves coming from the NE/ENE quadrant; the ENE component hits the exposed ESE-facing beach directly, while NE swells arrive slightly off the ideal angle. Air temperatures average only 8.6°C and water temps hover around 13.1°C, so the reward for braving the cold is generally clean, punchy waves with a winter bite. Precipitation is moderate at 2.39 mm/day, but high pressure usually returns quickly between passing fronts.
