September: Peak Sizes and Tropical Storms Line Up in the Eastern Pacific

September is the biggest month of the year on paper. Average swell height reaches 5.5-6ft (1.7m), the highest of the climatology, with a 12.9s average period. Swell direction is SSW at 59%, S at 17% and SW at 15% - all squarely in Pascuales' optimal window. The main difference is the tail of the distribution: around 13% of September's readings are 7-8ft (2-2.5m) or larger, as hurricanes and strong tropical storms pump serious energy into the Mexican swell window. This is the month to respect the ocean; heavy, powerful and potentially XL if a major storm tracks in range.

Wind is decent, with 41% ideal conditions. The SE and SSE quadrants are more present at 12% and 9%, which can create humidity and afternoon onshores, but the N/NE offshore window still opens often enough. September also averages 7.00 mm/day of rainfall - the wettest of the year - with air temps of 25.1°C and water temperature at 30.1°C. Expect storm clouds, warm water and a pulse-pounding combination of local and southern hemisphere swell.
