Conditions at Penarronda in March
March: Late-Winter Energy Still Packed
March is the first month of the meteorological spring, but the North Atlantic does not read the calendar. The average swell height eases only slightly to around 5ft (1.5m), and the period remains a solid 11.8s - still firmly in the powerful long-period range. NW swell leads at 35 percent, NNW at 25 percent, and WNW at 12 percent, meaning Penarronda continues to receive a steady conveyor belt of north-western groundswell.
The big change is wind: ideal offshore conditions drop to 36 percent, with SSW and SW flow totaling about 25 percent and S adding another 6 percent. There are more mixed days, but the cleaner winter swells are still frequent enough. Water temperature is 13.0°C, air temperature averages 10.2°C, and rainfall is 2.54 mm/day. March is a transition month, but if you play the windows, you can still find good 4-6ft (1.2-1.8m) waves with offshore winds and plenty of power.
