Conditions at Cardoso in April
April: Real Groundswells Return
By April, Cardoso's south-facing beach begins to wake up. S-directed swell climbs to around 17-18% of the total spectrum, with S contributing 14.1% and SSW another 3.1%. Average period jumps to 9.3s and average height reaches 1.7m (5-6ft). The extra S energy arrives at 1.5-2.5m (5-8ft), so the beach starts seeing proper overhead lines rather than trade-wind slop. The wind field is still favorable: NNE/NE flow totals 40%, and one-third of the month lands in the ideal offshore window. Water temp cools to 22.9°C and air to 22.6°C; with only 2.75mm/day of rain, it is the driest month of the year. April is the first month where you can legitimately score Cardoso on a mid-period S groundswell.
