Conditions at Nago in September
September: Small But a Bit Longer Period
September is the first subtle hint of change. The average height remains at 2.5ft (0.8m), but the period climbs back to 8.9 seconds, adding some needed push. Swell direction broadens: ENE 35 percent, NE 25 percent, E 15 percent, and NNE 14 percent. That increased north component gives Nago slightly better angles, and the longer period helps the waves wrap and hold shape. Wind quality remains excellent, with ideal conditions at 68 percent, driven by ESE 26 percent, E 19 percent, and SE 19 percent. It is still mostly waist-high surf, but the quality-to-size ratio is improving. Rain is at its lowest of the year, 5.49mm/day, air temp is 28.1°C, and water temp is 29.3°C.
