Conditions at Troia in April
April: The Spring Transition Begins
April marks a clear transition. The average swell height drops to 5ft (1.5m) and average period shortens to 11.1s - still surfable, but less of the heavy overhead power of midwinter. Wave directions remain dominated by WNW (36.7%) and NW (30.9%), with W (14.3%) still meaningful; SW and SSW contributions are small but present (2.1% combined). Swell heights cluster between 2-3ft (0.5-1m) and 3-5ft (1-1.5m) with a good number of 5-6.5ft (1.5-2m) sets, so fun, rippable conditions are common.
The issue in April is wind. Ideal conditions fall to 32%, and offshore NNE/NE/ENE/E flow drops to roughly 14%. The wind rose is led by NNW (24.6%) and NW (13.8%), which can create lumpy sideshore texture. Daily sea breezes also start to kick in as air temps reach 15.3°C. Water temp is 15.6°C, and precipitation is moderate at 1.78mm/day. Look for early mornings and any easterly wind event to find clean spring surf.
