Conditions at Costa Navarino in May
May: Summer Lull Begins
May is when the Mediterranean high pressure takes over and the surf at Costa Navarino becomes a marginal afterthought. The average swell height drops to 2ft (0.6m) and the average period falls below 5s to 4.9s, which is right in the choppy, low, messy zone. The swell rose shows massive NW/WNW dominance - together 44.5% of observations - but those are mostly windswell generated by the same NW winds that make the surface lumpy. The ideal SW-WSW-W window still provides about 37% of the directions, but almost all of it is under 3ft (1m).
Offshore winds are now a rare commodity, blowing only 12% of the time, and the afternoon sea breeze is the norm. The best bet is an early paddle when an E/NE drainage wind is still holding and the previous day's leftover W/NW swell has cleaned up. Air temperatures are warm at 19.1°C, water temperatures reach 19.3°C, and rainfall is low at 0.69 mm/day - great for swimming, less great for surfing.
