Conditions at Figueira Foz in May
May: Smaller Swells, Stronger North Wind
May is where the summer trend becomes obvious. Average swell height drops to 1.5m (5ft) and the average period shortens to 10.0s, meaning more windswell and less full-bodied groundswell. The swell is dominated by NW (35 percent), WNW (24 percent) and NNW (22 percent), with W adding another 10 percent. There are still fun, rippable waves in the 1-1.5m (3-5ft) range, but the wind is the problem. NNW winds are the dominant wind direction at 34 percent, and the ideal offshore wind drops to only 26 percent. Afternoon sea breezes often add cross and onshore chop. Air temps reach a pleasant 16.4°C, water is 16.4°C and precipitation averages 2.05 mm/day. If you can get a dawn session with an east wind, there is still fun surf to be found.
