Conditions at Stone Harbor in March
March: Spring Thaw with More Direction
March is a transition month. The average swell height remains 0.7m (2.3ft), but the period ticks up to 6.8s and ideal wind conditions reach 6%, the best of the winter months. Productive E, ESE, SE and SSE swell directions jump to around 41% of observations, driven by E at 10.5%, ESE at 10.3%, SSE at 11.0% and SE at 9.3%. This is the beginning of the spring-summer trend of onshore-directed swells, yet the decreasing frequency and strength of WNW/NW winds still leave plenty of offshore texture. The low-pressure storm track is weakening, but March can still deliver a final backhand slap from the North Atlantic. Water temperatures sit at 5.8°C, air averages 5.6°C and precipitation increases to 3.52mm per day, so expect cold, raw days with occasional punchy, rideable waves if the wind plays nice.
