Conditions at Unstad in April
April: Spring Transition
April is the last month with real winter energy at times. The average swell height drops to 1.2m (4ft) and the period shortens to 8.8s, but the wave rose shifts strongly toward the north. NNW swells account for 14.7%, NW for 9.9%, and the W through NNW sector totals about 40% of all swell - the highest of the year. The problem is size: many of those waves are in the 0.5-1m (2-3ft) range, so it can feel like a small-wave month.
Ideal offshore wind runs about 14% of the time. N through NE winds become more common and do not offer the same clean offshore grooming as the E to SSE quadrant. Air temperatures rise to 3.3°C, water temperature is still a cold 5.2°C, and precipitation drops to 2.36 mm/day. Spring is arriving, but winter can still punch through with an icy NW swell.
