Conditions at Manuel Antonio in October
October: Holding Size as the Season Fades
October is a classic transition month. The average swell height remains high at 4.6ft (1.4m), keeping the surf substantial, but the average period drops to 12.8s and the ideal wind percentage falls back to 19%. SW becomes increasingly important-35.6% of all waves now come from SW, alongside 62.9% from SSW-which actually suits the SSW-facing exposure very well and often delivers more lined-up, down-the-line waves. The 3-5ft (1-1.5m) range accounts for the bulk of the surf, with 11.2% of the total in the 5-6.5ft (1.5-2m) class. Rainfall peaks at 9.36mm/day and the water begins to cool slightly to 28.0°C, but there are still fun, powerful sessions to be found in between the tropical showers.
