Conditions at Imsouane in April
April: The Transition Begins
April represents the hinge point at Imsouane. Average swell height drops to 2.1m (7ft) and the period shortens to 10.8s, so the ocean becomes less groundswell-driven and more pulse-like. The NNW direction tightens its grip, accounting for 46.4% of all wave energy, with NW at 19.9% and WNW at 6.7%. Because so little of the swell comes from the S/SW quadrant, the bay becomes more shadowed and the waves less consistent; you need the better tides and a pick of the NW pulses. Wind is still good from the north: ideal offshore flow occurs 53% of the time, with NNW producing 35.2%, N 14.5% and NNE 11.5%. Air temps warm to 17.9C on average, water temperature is 17.2C, and precipitation eases to 0.56mm/day. This is a transition month: slower and less powerful than winter but a long way from flat.
