Conditions at Guethary in April
April: Smaller Swell, Trickier Wind
April is the real shoulder-season shift. Average wave height drops to 4ft (1.2m) and the period falls to 11.0s. The direction is actually still ideal - WNW 42.1% and NW 40.4% - but the energy is a notch down, with most waves in the 2-5ft (0.5-1.5m) range and only a minority reaching serious size. The swell is still mostly groundswell, so when a bigger NW train arrives the beach can line up nicely, but consistency and punch are lower than in winter.
The main challenge is wind: ideal conditions are only 29% of the time. W and WNW winds are frequent at 12.8% and 12.4% respectively, and NNW/NW flow adds more onshore energy. Early mornings are the key, before the sea breeze and local northwesterly kick in. Water temp begins to rise to 14.1°C and air temp averages 12.2°C; a 4/3 without a hood is usually enough. Expect fun, rippable surf rather than all-time slabs.
