The Lowdown
Alright, Rusty here. Let's get into it.
It is a flat spell, plain and simple. For the next week and a half, there's just no energy to speak of. From now right through until the 26th of August, the swell is tiny, mostly under 3 feet, and the wind is often onshore or cross-shore, making it messy or blown out. The best you can say is that there are some clean windows on Monday and Tuesday morning of this week, but with swell only around 2 to 3 feet, you're on a longboard or a log, and you’re working for it.
The only flicker of life comes right at the tail end of the outlook. Wednesday the 26th starts to see a change. There's a long-period groundswell arriving from the ESE, with a period of 15 seconds. That's a proper pulse, and the energy ramps up from moderate (104) in the morning to strong (207) by the afternoon. The wave height is still only around 1 feet, which sounds tiny, but that long period will push in more shape than the height suggests. The wind is clean, cross-offshore, and light to moderate, so the surface will be smooth.
Then Thursday the 27th is where it gets interesting. This is the standout window. The swell from the ESE holds at 2 feet, period of 12 seconds, and the energy is up again (140 in the morning, 201 in the afternoon). Now here's the kicker: Thursday afternoon we see offshore wind out of the W at 10 mph, with the forecast calling for "gentle offshore and clean" conditions. That is a big deal. For a break like Indian River (Northside), which is exposed to swell from the SSE direction, this ESE swell isn't perfect, but with that clean offshore wind, the waves will be tidy, peaky, and fun on the sets. It’s not big, but it’s quality. This is the best the whole two weeks has to offer.
The water temperature is 78°, which is about a touch warmer than usual for the time of year, so a spring suit will do.
If you're an expert looking for bigger, cleaner power, the last two weeks are a write-off. For everyone else, the only real show in town is that late Thursday, 27th of August, window at Indian River (Northside). Get on it if you can.
Rusty.
