Neixpa - surf spot statistics

Best Surf Season (December - February & July - September)

The heart of the surf year at Neixpa pulses during two distinct windows. Winter delivers reliable, long-period groundswells from the west and west-southwest, often generated by powerful North Pacific storms that refract into the south-southwest-facing coast. Combined with the highest occurrence of offshore winds from the north through northeast, December through February produce clean, punchy waves averaging 1.2-1.3m with periods around 13.7 seconds—perfect for lined-up walls. Summer flips the script as the Southern Hemisphere roars to life, sending direct, thick SSW and S swells across the equator. July through September see average wave heights climb to 1.5-1.7m, periods remain in the 13-second range, and wind ideal stays above 30%. These are the months when the offshore winter and powerful summer groundswell combine for the most consistent quality surf.

Fair Surf Season (March, June, October, November)

Transitional months bring a mix of potential and frustration. In March, swell energy remains high (1.4m average, 13.8s period), but wind ideal drops to 16% as the trade winds strengthen—morning sessions can still score clean, glassy conditions before the onshore builds. June offers a preview of peak summer with strong SSW swells (66.7% of all wave energy) and a rising wind ideal (23%), yet frequent westerly breezes often chop up the surface. October and November feature lingering southern swell and a return of cooler air, with wind ideal hovering around 31-32%. Expect solid 1.3-1.5m waves and long-period lines, but the windows of truly clean surf can be short-lived. These months reward those willing to be patient and pick the days when the wind aligns.

Low Surf Season (April, May)

Spring brings the most challenging conditions for Neixpa. Despite the largest average swell heights of the year (1.5m) and the longest periods (14.1 seconds), the wind ideal plummets to a mere 10-12%. The dominant swell directions shift to direct SSW and S, which would be perfect if the wind cooperated, but the easterly trade winds strengthen and often swing onshore, creating choppy, bumpy surf. Occasional early-morning glass-offs can yield clean, fun-sized waves, but overall, April and May are best tackled with a groveler or a forgiving shortboard. These months serve as a reminder that even great swell needs the right wind to light up.

August: Solid Southern Swell and Clean Air

August continues the summer winning streak with an average height of 1.6m, period of 13.2 seconds, and a wind ideal of 32%. Swell direction remains predominantly from the SSW (62.5%), with a good chunk from the south (27.0%). The direct fetch from the Southern Ocean means thick, powerful waves. Wind patterns show a healthy mix of easterly to offshore flows (E 12.0%, ESE 12.1%) that groom the faces. While westerlies still appear, the frequency of clean windows is high. Expect 1-2m waves most days, with occasional bigger sets when a juicy SSw swell fills in. Neixpa is in its prime during August.
