Conditions at Porth Neigwl in March

March: The Storm Track Starts to Fade

March is a transition month, but Porth Neigwl is still in business. Average swell drops slightly to 7ft (2.1m), though the period stays solid at 11.2s. The swell distribution actually becomes even more W-heavy, with W at 22.8%, WSW at 14.8% and WNW at 11.3%. The extra WNW energy means more variety, but also more opportunities for onshore wind to mess things up. Ideal wind rises to 18%, helped by building spring high pressure. The lighter winds and more mixed airmasses start to produce cleaner dawn sessions, but you still need to time it between systems. Water temp is at its annual low around 9.1°C with air at 9.0°C and precipitation easing to 2.42mm/day. A 5/4 remains the suit of choice, but the improving weather makes longer sessions more appealing.
