Conditions at Porzcarn in March
March: The Last Big Push
March keeps winter's pulse going. The average swell drops only modestly to 6ft (1.8m), the period remains a solid 11.5s, and ideal wind conditions nudge up to 19%. W and WNW swells dominate the waverose even more strongly than midwinter, with combined totals of 26.3% and 23.3% respectively; WSW adds another 12%, making for an excellent directional spread across Porzcarn's exposed walls. Although there is less giant swell than in January, there are still many pulses in the 5-8ft (1.5-2.5m) range, producing plenty of head-high-to-overhead surf. Spring warmth is tentative: air temps average 8.8°C, water temp 10.2°C, and precipitation eases to 2.05 mm/day. The Atlantic is starting to lose some of its bite, but March can still deliver some of the most powerful surf of the year before the summer flat spell takes hold.
