Conditions at Neixpa in September
September: Maximum Swell Size and Tropical Energy
September is the biggest month of the year at Neixpa. The average swell reaches 1.7m (5-6ft), the period is still deep at 13.0s, and the direction is SSW (58%) with S (21%) and SW (14%) contributing. This is when South Pacific winter swell peaks and eastern Pacific tropical cyclones can add extra pulse; a small percentage of over 2.5m (8ft+) waves even appears from SSW/SW. The 1.5-2m (5-6.5ft) category is substantial, and 2-2.5m (6.5-8ft) sets are not rare. Ideal wind is 30 percent, but the wind atmosphere is split between E/ESE (29% combined) and W (18%)/WSW (9%). Heavy rain (7.52mm/day), high humidity, air temps around 26.1C, and water temp of 29.8C are all part of the package. When a tropical system lines up with an offshore flow, this place can absolutely light up.
