Conditions at Guarda do Embau in May
May: The Full Power Window
May is where it all comes together. The average period jumps to 9.6s, tied for the highest of the year, while swell height holds around 4.3ft (1.3m). Direction-wise, the swell is now heavily loaded in the SE/SSE/S sector: SSE 18.9%, SE 17.4%, S 16.0%, and ESE 16.8%. More importantly, the 1.5-2m range fills in: S has 5.6%, SSE 4.0%, SE 3.7%, and there are 2-2.5m waves across every S to SE direction. Translation: long-period groundswell is moving toward the coast.
The wind starts to cooperate. Ideal offshore flow reaches 34%, and although N/NNE winds still blow at times, the frontal pattern brings more WSW to NW post-frontal gaps. With water at 21.2°C, air at 17.9°C and rain at 3.85 mm/day, conditions turn crisp and clean. May is a prime month for 5-8ft (1.5-2.4m) bombs when a proper S/SE groundswell lines up with NW winds.
