September: The Peak of the Year
September is statistically the best surfing month at Manazillo Bay. Average swell height peaks at 1.7m -- the highest of the year -- and the ideal-wind percentage also peaks at 48 percent. The swell mix is the most varied of the summer: 59 percent SSW, 20 percent S and 14 percent SW, with a few percent from the WSW, giving the bay a better blend of angles than pure summer months. The 1.5-2m (5-6.5ft) range is heavily represented, and a good chunk sits in the 2-2.5m (6.5-8ft) class. Long-period energy at 13.0s plus light, favorable winds around tropical cyclones and the tail of the southern-hemisphere season make this the month to plan a trip. Expect frequent rain at 7.65 mm/day and warm water at 30.1°C.
