The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming down the pipe for the next couple of weeks down at Indian River (Southside). I'll be straight with you, it's a bit of a flat spell for the most part, but there's a little light at the end of the tunnel if you're patient.
The immediate outlook is pretty grim. We're looking at a long stretch of tiny, poor-quality surf starting right now. From Friday the 14th of August right through to almost the end of the month, it's a real struggle. Waves are barely cracking a foot, if that, with combined swell energy bouncing around a paltry 6 to 42 – that's weak juice, folks. Most of this time, the wind is onshore or cross-shore, making a mess of what little bump there is. Monday the 17th gives us a little clean moment with some light offshore flow, but the swell is still tiny at 0.9 ft (0.3m), so it's barely worth a paddle. The water temp is about average for this time of year, nothing unusual to report there.
Now, let’s talk about the one bright spot. The best bet for the whole forecast window comes on Saturday the 29th of August. That morning we finally see some proper energy show up. The swell pulses up to 4 ft (1.1m) out of the ENE, and the combined energy hits 239 – that's a solid, moderate push. The wind is forecast to be light offshore, making for clean conditions. This is the standout. It’s still not a monster, but after two weeks of nothing, it's going to feel like a proper session. Expect some fun, rideable waves.
Before that, there’s a brief moment on Friday the 28th of August that’s worth a mention. The swell starts to build to 4 ft (1.1m), with glassy conditions in the morning and combined energy hitting 99 (just shy of moderate). It looks surfable, but the energy isn't as strong as the Saturday session, and the wind goes a bit messy in the afternoon. The Saturday is definitely the one to circle on your calendar.
So, in short, the first two weeks are a write-off for decent waves. If you've got to get wet, look for the clean windows, but don't expect much. The real action, and the only standout in this forecast, is Saturday the 29th of August. It'll be worth the wait.
Rusty.
