Conditions at Foz do Lizandro in May
May: Smaller Lines, Summer Wind Pattern Begins
May is the hydrologic hand-off from winter groundswell to summer micro-swell. The average wave height drops to 5.6ft (1.7m), with a noticeably shorter 9.9-second period. NNW swells (31.5%) now rival NW (30.5%) as the leading source, and while still from the favorable quadrant, the shorter period means less organized faces.
Wind becomes the limiting factor. NNW winds blow 36.5% of the time, making side-shore texture the norm. Ideal offshore windows nosedive to just 9%, meaning only the lucky dawn patrols score truly clean conditions. Air temps average 16.7°C, water climbs to 16.5°C, and rain is still present at 1.48mm/day. This is a funboard/performance longboard month, not a heavy shortboard one.
