Acapulco seasonal overview
Best Surf Season (December - March)
Acapulco's south-facing bay lights up during the Northern Hemisphere winter, when Southern Hemisphere storm tracks and the equatorial Pacific send consistent, long-period SSW and SW swell toward the Mexican coastline. Average wave heights sit in the fun-sized 3ft (0.9m) to 3-4ft (1.1m) range, but periods hover around 13-14 seconds, giving the waves real push and shape. Even better, the low sun angle and strong continental high pressure favor offshore N/NNE/NE/NNW winds, and the dry season keeps precipitation to a minimum. This is the most reliable window for clean, glassy surf at Acapulco.
Fair Surf Season (April - May and October - November)
The shoulder seasons offer a trade-off. Spring produces some of the biggest and most directional SSW swells of the year, with more 1-1.5m (4-5ft) and 1.5-2m (5-6ft) waves pushing through, but the wind dial becomes less consistent as westerly and SW sea breezes increase. Autumn sees a reverse pattern: the ocean is still warm from summer, hurricane-season leftovers can still fire, and as the ITCZ retreats and high pressure rebuilds, the offshore wind percentage climbs back toward 50-56%, making November a hidden gem.
Low Surf Season (June - September)
This is the rainy, tropical core of the year. Water temperatures peak near 30.8°C and precipitation jumps to 6-10mm/day during summer. Although average swell heights remain solid at 4-5ft (1.2-1.5m) and periods stay long, ideal wind percentages fall to 34-43%, with more onshore S/SSW/SW and thundery outflow winds. The S/SW groundswell energy is often there -- and hurricane swell can occasionally go XXL -- but the quality window is smaller and more fleeting. For the average surfer, this is the least consistent period for finding clean, ridable Acapulco waves.
