Salina Cruz, Mexico, is a wave-rich destination with consistent surf year-round, though the best conditions vary slightly across seasons. The spot is primarily powered by ground swells, which dominate from March through October, peaking at 96-98% probability from April to September—making this the prime window for quality, clean surf. The mean swell size remains steady around 1.1-1.3m, with October offering the largest waves at 1.3m. Wind conditions are the main limiting factor, as onshore winds prevail most of the year, particularly from November to March, when bad wind conditions exceed 80% probability. The best wind windows occur from May to September, reaching up to 30% good wind days in June, though even then, unfavorable winds are still common (70-74%). For surfers prioritizing swell consistency and cleaner conditions, the April-September period is ideal, with May and June standing out due to a slight uptick in favorable winds. However, expect some wind challenges regardless of the season. Late-season months like October can still deliver solid swells but with diminishing wind quality. If you're chasing the most reliable surf, focus on the mid-year months when ground swells are nearly guaranteed, and winds offer occasional clean sessions.
