The Lowdown
Alright, let me break this down for you. This is Sebastian Inlet-Third Peak, and I gotta be straight with you – the next 16 days are looking pretty grim for any decent surf action. We’re talking a long stretch of tiny, weak waves and variable conditions, with not a single standout session in sight.
The water temperature is sitting at a warm 83°, which is pretty much bang on average for this time of year – nothing unusual there.
The whole forecast period is a flat spell. We start off with Wednesday morning, the 12th of August, with a pathetic 0.7 ft of east swell at a short 6-second period, and combined swell energy is a measly 5 (weak). The wind is a light WNW cross-off, so the surface is clean, but there’s just no power to work with. That’s the story for the next few weeks – the swell height rarely pushes past 1 ft, and the period mostly stays under 10 seconds, so it’s all windswell and no grunt. The combined energy levels are almost all in the single digits or low teen range, which is flat-out weak.
There’s a gap of days with truly nothing on offer. The best we see is a tiny bump on Saturday afternoon, the 15th of August, with a 2 ft swell from the southeast, but it’s a short 4-second period and the wind is a moderate 20 km/h cross-shore, so it’s choppy and messy. Not worth paddling out for.
Even the glassy mornings – like Tuesday morning, the 18th of August, with zero wind and a clean surface – still have only 1.0 ft of east swell. The wave energy is just not there. The same goes for Wednesday morning the 19th, with a 1 ft swell and 10-second period, which is the longest period we see, but it’s still tiny and the combined energy only hits 34 (weak).
For an exposed beach and jetty setup like this, the conditions are so poor it’s honestly more interesting for kite surfing than paddle surfing, especially on the afternoons when the wind picks up from the southeast.
There’s no real standout, but if you’re desperate for a window, the morning of the 19th of August has the best relative conditions: 1 ft east swell at 10 seconds, light S cross-off wind, and clean surf. It’s still poor, but it’s the closest we get to something rideable. The swell direction is from the east, which is off the optimum NE direction, so it’s not even hitting the break well. Crowds are often a factor here, but honestly, with no waves, you’ll have the place to yourself.
Bottom line: leave the board in the shed. This is a 16-day stretch of tiny, weak surf with no real hope. It’s a blank run for the area, but that’s just how it goes sometimes. Forecasts can change, but right now, there’s nothing to get excited about.
