Acapulco - surf spot statistics

Best Surf Season (November - March)

The heart of Acapulco's surf calendar settles in from November through March, when the North Pacific high-pressure system weakens and the Aleutian low retreats. This pattern allows frequent cold fronts to sweep across the Gulf of Mexico, but for the south-facing shores of Acapulco, it's the long-period groundswell from the Southern Hemisphere that takes center stage. Swell directions lock into a consistent SSW to SW band, with average heights hovering around 0.9–1.1m and periods stretching to 13–14 seconds. Combined with ideal wind percentages peaking at 58% in December and 56% in November (thanks to frequent light northerlies and offshore breezes from N, NNE, NE, and NNW), this window delivers the cleanest, most rippable conditions of the year. It's when the combo of groomed faces and punchy swell lines truly shines.

Fair Surf Season (April - June & October)

As spring transitions into summer, the trade winds begin to build and the Pacific storm track shifts south. From April through June, average swell heights climb to 1.2–1.4m, and periods remain solid in the 13–14 second range. The swell direction remains dominated by SSW (often 70–90% of the total), so the potential for good waves is high. However, the offshore wind window narrows. Ideal wind percentages drop to 34–40% as the region sees more frequent onshore flow from the SW and W, especially during afternoons. October marks a return toward more stable patterns, with ideal wind at 46% and still‑decent swell from the Southern Hemisphere. This is a transitional season—expect glassy mornings with building afternoon seabreezes. Surfers who chase the early windows will find fun, solid waves on the better days.

Low Surf Season (July - September)

Summer deepens into the heart of the Eastern Pacific hurricane season, and Acapulco's wave quality suffers from a classic conflict. Swell heights remain robust, averaging 1.3–1.4m with a mix of SSW and S directions, and periods still in the 13‑second range. But the wind patterns become erratic: the region is sandwiched between the North Pacific high and developing tropical systems, leading to a higher frequency of onshore winds from the S and SW. Ideal wind percentages bottom out at 34–43%, and those light northerlies that define the best season become scarce. Even when swell is plentiful, the prevailing onshore flow and occasional storm‑related wind shifts quickly chop up the surface. It's not a total writeoff—early mornings can still deliver clean, long‑period lines before the wind kicks—but overall, this is the least consistent period for quality surf at Acapulco.

July: Summer Swell Patterns, Slightly Better Winds

July sees average swell relax slightly to 1.3m, with a period of 13.6s. The swell shifts a bit: S (23.8%) increases while SSW remains the driver (72.6%). Wave heights still feature 1–1.5m (72.2%) and 1.5–2m (23.4%), with occasional 2–2.5m sets (1.5%). The ideal wind percentage improves to 43% as the wind becomes more variable. Light E, ESE, and SE winds increase, and the afternoon W flow (19.1%) is still present but somewhat weaker than in May and June. There are more early‑morning windows with glassy conditions. July offers a mix—good swell potential with a slightly more forgiving wind schedule than the previous two months. Mornings can be excellent before the sea breeze kicks up.
