The Lowdown
Alright, Rusty here. Let me tell you straight: this 16-day window is a tough one for Indian River (Southside). The setup is a beach/jetty spot, and it’s not getting much to work with. The water temp is sitting at 78° right now, which is much warmer than normal for this time of year, so you’ll be sweating in your wetsuit.
Honestly, for the first week and a half, we’re looking at a long stretch of flat to tiny conditions. From Monday the 7th right through to the start of the second week, there’s just no meaningful surf on offer. Swell heights mostly hover around 0.7 ft to 2 ft, and the combined energy is weak – often in the low double digits like 10 or 20. It’s a pretty blank run, which isn’t too unusual for this area when the swell windows don’t line up.
The first real glimmer shows up on Thursday the 10th in the afternoon. We get a glassy window with a 4 ft swell from the south, period around 6 seconds. The combined energy is 81, still weak, but glassy conditions are rare here. It’s just ordinary surfable waves – small, short period, but clean as a whistle. That’s the best of a bad bunch.
Early in the second week, Monday the 14th afternoon, there’s a 3 ft south swell with a 5-second period and 63 combined energy, but the wind is cross-shore and moderate, so it’s choppy and messy. Not worth getting excited about.
Tuesday the 15th morning brings a 3 ft NNE swell, period 5 seconds, with clean offshore wind from the WSW. The combined energy is 60. It’s small and weak, but clean. Again, just ordinary.
Wednesday the 16th and Thursday the 17th get blown out by strong breezes and some heavy rain. Not the day for it.
The final weekend, Saturday the 19th, stays clean with offshore NW wind, but the swell is tiny at 0.7 ft, with a long 12-second period from the ESE and combined energy of 43. That long period means better shape, but there’s almost no height to ride. For a beach/jetty break, that long period swell might just slide through without much punch.
All in all, there’s no standout here. The best session is that glassy Thursday afternoon, but it’s small and short period. If you’re after a paddle, you’re better off waiting for the next weather system to bring something proper.
Rusty, signing off.
