Conditions at El Mongol in April
April: Shoulder Season Shapes
April brings the first real slowdown. Average wave height eases to 4ft (1.3m) and period drops to 10.6s. The swell direction is still overwhelmingly NW and NNW, making up 40% and 28% respectively, but most of the energy sits in the 2-5ft (0.5-1.5m) range. Ideal winds are present only 33% of the time, and ENE winds are the clear leader at 15.9%, with E and W winds also common, so clean sessions tend to come in the early morning or behind cold fronts. Water temperature climbs to 13.7°C, air averages 11.9°C, and spring rain remains present at 2.48mm/day. This is a transition month: too inconsistent for epic waves, but with enough northwesterly swell to keep a shortboard interesting.
