Conditions at Westbrook in April
April: Autumn Transition Opens the Clean-Window Season
April is where Westbrook begins to fire with consistency. Swell height stays at 5-6ft (1.7m), period pushes to 10.0s, and ideal wind climbs to 35%. Swell directions spread across the target zone: SSE 20.0%, E 17.9%, SE 17.5%, ESE 15.5%, plus 14.9% S. The S component matters - it is generated by the first serious frontal systems of the season, and it refracts into the SSE/SE lines that work so well at this beach. Wind observations still show NE (14.7%) and SSW (15.1%) as the heavyweights, but the offshore W/WNW/NW/NNW group now totals 11.9%, with NNW alone at 5.2%. This is the month where dawn patrol becomes a habit: clean, lined-up, rippable 3-6ft (1-2m) waves with occasional 6ft (1.8m) sets, and drier autumn air making it all feel easier. Water temp 24.2°C, air 22.3°C, rainfall 1.70 mm/day.
