Conditions at Barrio in May
May: The Summer Cleanup Begins
May is when the surf quality story changes from size to cleanliness. Average swell height drops to 2.6ft (0.8m) and the period eases to 9.1s, but the wind rose rotates strongly into the offshore quadrant. ENE remains the dominant swell source at 67%, though most of it is now small, with 56% of all readings in the 2-3ft (0.5-1m) range. E and NE directions add the rest of the north-eastern energy. The trade winds fade and the southwest monsoon begins to breathe, pushing ideal S/SW offshore flow up to 34% of the time. This makes for many clean, glassy sessions, but wave height is the limiting factor. Water temperature climbs to 29.4°C and rain is at a seasonal low of 5.5mm/day, so between the small sets there is plenty of time to soak up the tropical sun.
