Sayulita, Mexico, offers consistent surf conditions year-round, but the best months for surfers typically fall between November and May, with peak conditions in winter. The most reliable ground swells occur from January to May, with January standing out as the prime month—93% ground swell, a manageable 0.9m mean size, and 21% good wind days. Though winds are often onshore (79% unfavorable in January), the clean, energy-rich swells compensate. February sees a slight dip in ground swell dominance (59%) and smaller waves (0.7m), but conditions remain surfable. March and April maintain decent ground swell (65-77%) but suffer from higher bad wind rates (86-89%), making early mornings or protected spots preferable. May marks a return to stronger ground swell (84%) and slightly improved winds (21% good). Summer (June-September) brings mixed conditions: increased wind swell (27-39%) and more variable swell consistency, particularly in July and August, when no-swell days spike (28-36%). However, September offers the best wind conditions (43% favorable) despite the swell mix (54% ground, 39% wind). October transitions back toward winter patterns, with ground swell rising to 64% and modestly improved winds (27% good). December closes the year with solid ground swell (72%) and manageable winds (29% good), though wave heights stay modest (0.7m). For surfers prioritizing quality over consistency, January reigns supreme with powerful, clean ground swells. Those willing to trade swell purity for fewer crowds might target September’s cleaner winds or May’s reliable ground swell. Summer months are better suited for beginners or flexible surfers tolerant of wind chop and smaller waves. Avoid July and August if seeking premium conditions, as swell consistency drops notably. Overall, Sayulita’s year-round surfability makes it a versatile destination, but winter delivers the most polished waves.
