The Lowdown
Alright, Rusty here. Let’s have a look at the next couple of weeks.
Honestly, it’s a flat spell for Sebastian Inlet-First Peak. We’ve got a long, dry run ahead. From today, the 17th of August, right through to the 26th of August, the swell is tiny, barely breaking 1 foot. The combined wave energy stays well below 100 all that time – we’re talking weak, anemic energy. It’s mostly short-period, windswell junk, and the wave comments say it plainly: "poor surf conditions." Not worth getting wet for.
The wind does offer some clean windows, like Monday afternoon (17 Aug) with glassy conditions, and a few mornings with light cross-off breezes, but there’s just no push behind it. For a beginner, it’s safe but dull; for anyone else, it’s a full-on skunk.
We finally see a little pulse of energy on the morning of the 27th of August. Swell bumps to 2 feet from the east, with a period of 13 seconds – that’s a bit of groundswell character. The combined energy climbs to 131, which is moderate. The wind is light and cross-off from the WSW, so it’ll be clean. The forecast says "surfable waves but very ordinary conditions." It’s not a standout, but it’s the first real chance to paddle out in over a week.
The next morning, the 28th of August, is similar: 2 feet east swell, 11-second period, light cross-off from the west, clean. Energy is 198. Still ordinary, but rideable.
The 30th of August morning is worth a mention. Swell is 3 feet from the NE, period only 8 seconds (short-period), but the wind is a clean 9 mph offshore from the SW. Combined energy is 90 – dropping back to weak. It’s clean and offshore, but the wave quality will be limited by that short period and lack of power.
And then we roll into September 1st with a glassy morning, 3 feet from the ESE, but a period of just 5 seconds. That’s pure windswell chop, and the energy is weak at 55.
So, overall, there’s no true standout window. The best on offer is the morning of the 27th of August with that longer-period groundswell and clean conditions, but even that is very ordinary. The water temp is sitting around 84°F, which is about average for the time of year, so no surprises there. If you’re desperate, aim for those clean mornings from the 27th onward, but keep your expectations in the gutter.
Rusty.
