Salina Cruz - surf spot statistics

Best Surf Season (October - March)

The North Pacific and Gulf of Tehuantepec roar to life during the autumn and winter months, kicking up the most consistent and powerful swell of the year. Average wave heights climb to 1.6-1.8m (5-6 ft) with periods often reaching 9-10 seconds, offering solid, punchy surf at this east-facing setup. The dominant swell sources shift between long-period Southern Hemisphere pulses wrapping in from the SSW and regional NNW groundswell generated by Tehuantepec gap winds. While the wind machine is often active – the infamous northerly 'Tehuanos' can howl at 30-40kph and degrade conditions – the windows of offshore flow from the west and northwest are pure magic. This is when Salina Cruz lives up to its reputation as Mexico's answer to Indonesia, with strong, rippable waves and the occasional heavy, pumping day. November and December average the highest swell heights, though the cleanest combo often comes in late January and February when the wind is marginally more cooperative.

Fair Surf Season (April & September)

April and September serve as transitional bookends. Swell heights dip slightly to around 1.5m (5 ft) but the wave periods extend nicely into the 12-second range, meaning fewer but more powerful sets. The Tehuantepec winds start to ease in April, handing more time to lighter breezes and occasional offshore conditions from the west. September benefits from increased tropical activity in the Eastern Pacific, which can spin up distant south-southwest swell trains that march into the coast with excellent period. These months are a gamble: you might score empty, long-period gems with smooth conditions, or you might sit through wind-affected crumbly waves. A 30-35% chance of clean surf keeps the dedicated surfer on their toes.

Low Surf Season (May - August)

From late spring through summer, the swell dials down and becomes fickle. Average wave heights drop to 1.4-1.5m (4-5 ft) and the energy is largely moody, with long periods but inconsistent sets. The dominant swell direction shifts to S and SSW, often wrapping in with enough period to produce fun-sized waves, but the overall size rarely exceeds the 1-1.5m 'fun, good' range. The saving grace is the wind: this is the best time of year for offshore conditions, with ideal wind percentages climbing above 40% and peaking near 50% in July. The dreaded northerly 'Tehuanos' are almost absent, replaced by light mornings and afternoon sea breezes. For the patient surfer, early morning sessions can deliver clean, small-wave groveling or even a sneaky chest-high set. But the massive, XL days are virtually nonexistent – this is the low season for a reason.

May: Long Periods, Fickle Size

May settles into the low season with an average height of 1.4m (4.5 ft) but the longest average period of the year at 13.6 seconds. The swell is overwhelmingly from the SSW (64%), with a good portion in the 1-1.5m and 1.5-2m categories – solid fun to good waves. The wind improves, with ideal conditions 34% of the time. N wind drops to 22%, and lighter breezes dominate. The real challenge is consistency: the long-period nature means waves come in sets with lulls in between. This is a month for the dedicated surfer who appreciates quality over quantity. Early mornings often deliver offshore W to NW flow, making the most of the infrequent but peaky sets. The sea surface temperature rises, and the vibe becomes more tropical and relaxed.
