The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming up for Indian River (Southside). Gotta be straight with you – the next 16 days are looking pretty grim. We’ve got a long stretch of small, weak surf, and the wind is rarely on our side. The first solid window doesn’t even show up until Sunday the 19th, and even then, it’s nothing to write home about.
The pattern for the first week plus is all about tiny, short-period leftovers. The combined swell energy is laughable, most of the time in the teens or twenties (like 16 to 23), which is barely a ripple. The water temp is 76°, a touch warmer than normal for this time of year, so at least you won’t freeze waiting for a wave.
The only real standout in this whole 16-day stretch is the afternoon of Sunday the 19th. The wind will be light and cross-offshore from the NNW at 6 mph, keeping things clean. A small swell from the SSE bumps up to 4 ft, with a period of 7 seconds and a combined energy of 255, which is actually moderate. Expect good surf conditions, but it’s still a beach/jetty setup, so the short period means it’ll be a bit crumbly. For the advanced crew, it’s the best we’ve got.
Monday morning the 20th is glassy with a 3 ft SSE swell, but the energy drops to 100 and the wave quality is just “ordinary.” Tuesday afternoon the 21st has another pulse of 5 ft from the SSE with a 6-second period and 205 energy, and light cross-off winds, which is surfable but again, short period.
After that, it’s back to the small stuff. The runs from the 22nd through the 30th are all tiny, messy, and mostly cross-on or onshore. There’s a glassy morning on the 29th with a 2 ft ESE swell, but with only 64 energy, it’s barely a bump.
Honestly, if you’ve got a kite, the afternoon of the 18th has a 4 ft S swell with a 16 mph cross-shore wind, which might be more interesting for you than for a paddle surfer. Otherwise, for the rest of the time, save your energy. The surf is poor, the consistency is poor, and the wait for anything decent is long. Forecasts can change, but right now, it’s a quiet stretch.
Rusty.
