The Lowdown
Alright, surfers. Rusty here.
To be straight with you, looking at this 16-day window for our area, we’ve got a long, slow stretch of flatness and poor conditions ahead. The first few days are a write-off, with tiny, weak swells and messy wind. It’s not looking like there’s a single standout session worth paddling out for. Let’s break it down.
The run starts on Sunday, August 30th, and honestly, it’s a no-go. We’re talking ankle to knee-high slop from the east at 2ft with a short, weak 6-second period. The combined wave energy is barely a whisper (40), and with a risk of thunderstorms and a cross-onshore breeze, it’s pretty miserable. That pattern of tiny, poor surf continues through the first week. Monday and Tuesday offer nothing better – still 2ft, short-period junk, and unfriendly winds. Even when we get a glassy moment on Saturday, September 5th, the swell is so tiny (1ft) it’s barely a ripple. The water temperature anomaly isn't flagged here, so it’s about average for this time of year.
We then hit a big dead zone. From Sunday, September 7th through to Friday, September 12th, the swell is basically non-existent, with heights from 1ft. This is a proper flat spell. The combined energy readings are in the single digits and low teens – that’s as weak as it gets. You'd be better off finding something else to do.
Now, there’s a flicker of hope right at the very end of the window. By Sunday, September 13th, we see a new pulse of swell start to push in. The morning is still tiny (2ft) from the NNE, but by the afternoon it builds to 3-4ft from the NE. It’s still short-period (6 seconds) and the wind is cross-onshore from the ESE, so the setup at Sebastian Inlet-First Peak will be a bit choppy. But after two weeks of nothing, 3-4ft is at least something to look at. The combined energy is still only moderate (81), so don’t expect any power. It’s a far-off preview of a change, but it’s not a green light. There’s also a small 3ft pulse on Monday the 14th, but again, with a cross-onshore wind and short period, it’s a pass.
So, the honest truth is there are no good options in this 16-day stretch. For this area, a blank run like this isn't unusual, but it's still frustrating. The surf just isn't there. Keep your gear dry.
Rusty.
