Conditions at Barley Cove in March
March: Winter Power Meets Spring High Pressure
March is the last full month of meteorological winter, but quieter weather begins to creep in. Average swell eases to 8.9ft (2.7m), the period remains a solid 11.6s, and ideal wind improves to 22 percent. W and WNW dominate the wave rose, while the S and SSW share rises slightly, with SSW alone reaching 2.9 percent. The wind distribution is more balanced, with NNW and NW both playing strong roles and lighter speeds more common. That makes March an excellent transition month: you still get winter's power, but the chances for clean, offshore conditions are better than in December or January. Early spring high pressure over Scandinavia can generate a true north or northeasterly offshore breeze at Barley Cove, grooming those long-period south swells into crisp, rippable walls. Water temperature sits at 9.3°C, air at 8.5°C, and average rainfall drops to 3.39 mm/day - a sign that the persistent wet winter is easing.
