The Lowdown
Alright, Rusty here again with the same look, but in feet and old-school units.
We’re staring down a 16-day window at Sebastian Inlet – First Peak, and to be blunt, there’s nothing doing. It’s flat, it’s messy, and it’s not worth the drive.
Water temp is around 84°, which is about average for late summer around here. That’s the only thing that’s normal.
From Tuesday the 1st right through to Wednesday the 16th of September, it’s all poor surf conditions. Swell heights barely push 2 feet on the best day, and most days it’s a piddly 0.6 to 1 feet. Wind is mainly onshore or cross-onshore out of the east or southeast, which just wrecks what little bump there is. A few mornings like the 5th, 6th, and 7th of September go glassy, but with no swell, it’s just a flat, shiny lake. Wave energy numbers are pathetic – mostly in the single digits or teens.
The whole period looks better for a kite than a surfboard. No standouts, no hope spots, just a dead run. Don’t get too down – forecasts can flip – but right now, leave the stick at home.
Rusty.
