The Lowdown
Alright, Rusty here. Let’s break this down for Indian River (Southside).
Look, the honest truth is we're in a real dry spell. From now through the middle of the next two weeks, there’s hardly a wave worth paddling for. The combined swell energy is mostly in the weak range – single and low double digits – which tells you there’s just no power in the water.
Starting Sunday the 16th right through to about Wednesday the 26th of August, it’s mostly flat. Swell heights are almost always under 3 feet, and the periods are short, meaning no push. Winds are often cross-shore or onshore, chopping up anything that tries to form. The one exception is Monday the 17th morning and afternoon, when a light offshore breeze from the WNW and NW cleans it up, but we’re still looking at a weak 3-foot windswell. It’s not nothing, but it’s not worth a special trip.
The only real standout falls on Thursday the 27th. The afternoon of the 27th, we get a bit of life. Swell direction from the ESE with a 12-second period – that’s groundswell – and the combined energy jumps to 207 (moderate). The wind goes offshore from the W at around 9 mph, glassing it up. This is the only window where the jetty might offer a few proper, clean waves. Swell size is only about 2 feet, so it’s small, but with that offshore wind and long period, it could actually be fun for a patient surfer.
Indian River (Southside) is an exposed beach and jetty break, best on a SSE swell. Water temp is sitting at 78°, which is a touch warmer than normal for the time of year, so the water feels good when you’re waiting.
Thursday the 27th afternoon is the one to circle. Everything else from the 16th through the 31st is a miss. It’s a long, quiet stretch for this area.
