Costa Azul, Mexico, offers consistent surf conditions year-round, with ground swells dominating the swell regime almost every month. The best surfing months are typically from March through September, when ground swell consistency is highest (peaking at 99% from March to May) and wind conditions are favorable. March, April, and May stand out with excellent ground swell reliability (99%) and good wind conditions (61-67%). Swell size gradually increases from spring into summer, averaging 0.8-0.9m in spring and peaking at 1.1-1.3m from May through September. Late summer (July-Sept) sees slightly more wind swell interference (11-16%) but maintains solid wave height (1.2-1.3m) and reasonably good wind conditions (55-58%). The fall months (Oct-Nov) still provide decent surf, with ground swells remaining dominant (88-92%) and swell size tapering to 0.9-1.1m. Winter (Dec-Feb) brings smaller waves (0.8m) and less favorable winds (winter months average 43-56% good wind days), but ground swells remain strong (88-95%). For the best balance of wave quality and wind conditions, late spring (April-May) is ideal, offering clean, consistent waves with minimal wind interference and gradually increasing swell size. Advanced surfers may prefer the slightly bigger summer waves (June-Aug), though wind conditions are marginally less reliable. Overall, Costa Azul provides dependable surf year-round, with peak conditions centered around the spring and early summer months.
