Conditions at Assinie in April
April: Solid Long-Period Swell, Tricky Conditions
The swell machine is in full transition now. April produces an average swell height of 3-4ft (1.1m) and an average period of 11.5s, with the majority of S-energy (54.4%) sitting in the 3-5ft (1-1.5m) range and a small but real share of overhead 5-6.5ft (1.5-2m) sets appearing. Direction-wise, 78.4% comes from S and 21.5% from SSW, an ideal setup for Assinie's SSW-facing coastline. Ideal wind is only 4%, though, as the SW/SSW monsoon becomes more embedded.
Winds from SW (35.6%), SSW (26.5%) and WSW (15.5%) dominate. Add in 5.83mm/day of rain and humid air at 27.5°C, and you have classic tropical onshore conditions. It can still be fun if you pick a morning before the onshore wind builds, especially with water temperature at 28.5°C and long-period swell wrapping in.
