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.

March: Transition and Swell Trade-offs

March marks the last hurrah of winter-style swell before spring patterns take over. Wave heights average 1.4m with a 13.8-second period—great for power. The distribution shifts: SW swell jumps to 44.3% of all wave energy, and SSW becomes more significant at 19.7%. However, the wind ideal drops to only 16%, as onshore westerlies dominate (W 24.2%, WSW 17.9%). This makes morning glass-offs critical for clean conditions. When the wind cooperates, the combination of solid SW groundswell and good period offers excellent, lined-up surf. But be ready for afternoon chop.
