Conditions at Altura in April
April: Shoulder Season and Shorter Periods
April is the transition month when winter groundswell gives way to a less organized Atlantic. Average size drops to around 2ft (0.7m) and period falls to 6.1s, so the surf becomes more wind-swell-influenced and less powerful. The southern quadrant stays visible in the data: SE is 11.0 percent, SSE 5.4 percent, S 3.5 percent and SSW 4.1 percent, with some 3-5ft (1-1.5m) waves from the southeast. However WSW and W now account for over 40 percent of all energy, and that raw west energy does not line up with this SSE-facing beach. Wind is still reasonably good with NNW at 22.0 percent and NW at 12.1 percent, but ideal conditions fall to 35 percent and onshore SW/SSW winds become more common. Water temperature warms to 17.0C, air averages 16.1C, and rain is 1.92 mm/day. April requires you to pick smaller southern windows carefully.
