Conditions at Sebastian Inlet in October
October: The Autumn Turn
October is a serious upgrade. The average swell rises to around 3ft (0.9m), period holds at 8.5s, and the wave rose becomes much more energetic: ENE accounts for an impressive 43.2% of all swell, with E at 21.5% and NE at 19.9%. This is the month when the frequency of solid 3-5ft (1-1.5m) and 5-6.5ft (1.5-2m) ENE/NE energy really jumps, thanks to developing nor'easters and lingering tropical systems. The catch remains wind: favorable flow is only 17% of the time, with the wind rose dominated by ENE (18.1%), NE (14.4%), E (12.0%) and NNE (10.1%). That means a lot of the incoming swell is accompanied by onshore wind. Still, when a cold front pushes through and the wind swings to W/NW behind it, the surf at Sebastian Inlet can be firing and clean.
Air temps cool to 24.6°C, water remains pleasant at 27.2°C, and rain drops to 4.01 mm/day. October is all about timing the fronts.
