Conditions at Mareta in April
April: Spring Calm and Shorter-Period NW Swell
The North Atlantic starts to exhale in April, with average swell height easing to 6ft (1.9m) and period softening to 11.1s. NW remains the dominant direction at 34.1%, supported by WNW (21.5%) and NNW (13.6%). This is still a north-dominated swell regime, so Mareta's south-facing exposure remains dependent on refracted energy and the occasional southerly pulse. Offshore winds are consistent - NNW (32.7%), NW (13.9%) and N (5.2%) - but the ideal wind rating drops to 24%. With water temp at 16.3°C and air averaging 15.8°C, spring is beginning to feel warmer, but the surf is slowly losing its winter push.
