April: Offshore Winds Hit Their Stride
April is where the stars start to align for Westport Breakwater. The average swell height increases to 2.3m (7.5ft), wave period holds at 12.4s, and ideal wind conditions click up to 50 percent-the first of several consecutive months of high-quality offshore wind windows. The swell remains WSW-dominated (44.6 percent), but the distribution is now heavily stacked in the 5-8ft (1.5-2.5m) range, with W adding 8.9 percent and WNW/NNW/NW contributing another 9.1 percent. The mix of long-period westerly energy and increasing northwesterly components produces good shape at the north-facing breakwater.
Wind data shows a beautiful south-southwest corridor: SW at 17.6 percent, SSW at 10.4 percent, and S at 6.0 percent. Onshore N/NNE/NNW/NW winds drop to about 17.5 percent, making April one of the most reliable months for groomed, powerful surf. Water temperature is still reasonable at 15.9°C, air averages 13.2°C, and precipitation rises to 4.69 mm/day-those April showers are the price you pay for the first true autumn swells.
