Conditions at Mira in April
April: Swell Drops and the North Wind Builds
April is the transition month. Average wave height drops to 6.5ft (2.0m), the average period falls to 11.0s, and the ideal-wind score slips to 29 percent. The swell direction distribution is still excellent - NW (27.4 percent), WNW (23.2 percent) and NNW (15.1 percent) - meaning the beach still sees regular pulses of W-NW groundswell. The problem is wind: the Azores High is starting to build, driving a persistent NNW flow at 24.6 percent, with NW wind adding 10.2 percent. These are cross/onshore winds that chop up what could otherwise be clean overhead surf. The best windows are early morning or on days when an E/ESE breeze develops. Water temp climbs to 15.1C (59F), air averages 13.9C (57F), and rainfall stays around 2.91mm/day. April can deliver, but you have to be selective.
