Conditions at Newport in March
March: The Autumn Gears Begin to Shift
March is the first month when Newport can genuinely be good. Average swell is 4-5ft (1.2-1.5m), average period climbs to 9.0s, and favourable winds increase to 22%. The swell rose is still heavily east-based-E 21%, ESE 21%, SE 20%, SSE 19%-so the beach is rarely flat. Wind direction becomes more westerly: WSW/W/WNW/NW now account for about 10% of observations, double the summer share, which opens up cleaner windows. Air temperatures cool to 21.0°C, water holds at a warm 22.6°C, and rainfall drops to 3.33 mm/day. This is the classic month for warm-water, glassy, E/SE groundswell sessions before the winter pattern fully locks in.
