Conditions at Sandvik in March
March: Equinox Swell and Longer Windows
March starts the slow transition out of winter while still holding plenty of punch. Average swell height is a solid 7ft (2.2m) with an 11.0s period, meaning the Atlantic is still sending powerful, rideable groundswell. The dominant directions are SW (16.0%), SSW (10.8%), WSW (8.6%) and S (7.7%)-again a fantastic setup for Sandvik. The wind field starts to become a little more favourable: ideal offshore conditions reach 11% of the time, with strong NNE and NE components still present. Longer daylight and slowly warming air (average 1.5°C) make the waiting game more bearable, though Arctic fronts can still plunge temperatures to -12°C. Water temperature sits around 5.2°C with precipitation at 4.58mm/day. March is that sweet spot where the winter swell machine is still running, but the atmosphere is beginning to offer cleaner post-frontal offshore days.
