Conditions at Unstad in March
March: Winter Hangs On
March is still a very good month, with the average swell height at 1.6m (5ft) and the average period at 9.6s. The SSW, SW and WSW block remains dominant, but the NNW swell component grows to a substantial 11.4%, making this month one of the better transitional periods for clean, north-of-west swell. The ideal wind frequency improves to 14%, the best of the winter, yet the offshore flows are often moderate to strong, especially from SE and SSE.
Water temperature sits at 5.2°C, air temperatures average 1.6°C, and precipitation drops slightly to 3.12 mm/day. March is the month to squeeze in as many sessions as possible before the spring relaxation begins. If you pick the right window, the combination of NNW groundswell and cold offshore wind can produce glassy, powerful waves with very few people in the lineup.
