Conditions at Yport in March
March: Early Spring Swell and North Sea Windswell
March is a transition month. The average swell height drops to 1.2m (4ft) and the average period is 8.1s, so the surf still has some punch. The wave rose becomes even more westerly, with W at 32.3% and WSW at 17.0% combining for nearly half the total energy, while NNE and NE swell contributions grow to a combined 13.5%. These north-easterly waves are usually short-period and windblown, and the accompanying NE/NNE winds are onshore or cross-onshore for Yport.
Ideal offshore wind still blows 16% of the time, so there are good days to be had when S/SW winds align with a N/NW swell. Air temperature averages 7.6°C, water temperature is 8.0°C (46.4°F), and precipitation drops slightly to 1.79 mm/day. Late winter lows can still deliver solid 1.5-2m waves, but as the month goes on, the trend is toward smaller, cleaner, less powerful surf. It's a good month for a shortboard and patience.
