The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for Indian River (Southside).
Right off the bat, I gotta be straight with you—this stretch of the next two weeks is looking pretty grim. The first recommendation doesn't come up until the morning of the 15th of September, so we're staring down a solid, say, ten-day gap with nothing worth paddling out for. The water temp is sitting at a balmy 77°F, which is a full 5°F warmer than normal for this time of year, so it’s a bit of a warm bath out there, but the wave quality just isn't there.
From the 4th right through to the 14th, it's a string of poor surf conditions. We get a few moments of clean conditions, like the morning of the 8th with a light WNW cross-offshore breeze, but the swell is tiny—only 1 ft from the ENE with a short period. The combined energy is weak, barely registering (42). The 9th of September afternoon sees a jump in wind to 19 mph from the SSW, which is clean, but again, the swell is a messy 4 ft from the S with a period of just 5 seconds—no shape to it. The 10th of September morning has a fresh offshore from the WNW at 19 mph, but the swell is only 2 ft from the S (48 energy). It’s all just a lot of wind and not much wave.
The first real flicker of hope comes on the morning of Tuesday the 15th of September. The wind drops to glassy, and we get a little bump of swell—4 ft from the S. The combined energy climbs to 172, which is moderate, but the period is only 6 seconds, so it's a short, weak wind swell. The report says "surfable waves but very ordinary conditions," which is about as enthusiastic as I can get. It's not a standout, but it's the best we've got. The glassy conditions are a major positive, though, so the surface will be clean.
Then on the morning of Friday the 18th of September, we get another chance. It's glassy again, with a 2 ft swell from the E (59 energy). Still small, still ordinary, but the wind is perfect. Both of these mornings are the only times the score even gets a 1 out of 10, so that's your window.
In short, don't plan a surf trip around this. If you're local and desperate, the 15th and 18th of September mornings are your only real shots, and even then, keep your expectations low. The rest of the run is a total write-off.
Rusty.
