Conditions at Refsnes in March
March: Spring Tension
March is the last full month of true winter energy, though the power is already easing. Average swell height lowers to 6ft (1.9m), the period remains respectable at 8.7s and the ideal SSW-to-W window again contributes around 26 percent of the swell. However, the balance shifts further toward northwest energy, with NW and WNW combined making up more than 30 percent of all wave observations. That means Refsnes sees a lot of secondary, side-shore swell, so clean W/WSW days become more precious than they were in January.
Wind is ideal 18 percent of the time, with NNW and SE winds still battling for dominance. Spring high pressure often brings lighter days and occasional E/NE offshore breezes, which make even average 4-6ft (1.2-1.9m) swell feel punchy and well-ordered. Water temperature hits its annual minimum around 4.8°C, air averages 3.1°C and precipitation eases to 4.19 mm/day. A good March session is a fading W/SW swell, an E-to-NE offshore wind and cold, clean spring water.
