The Lowdown
Alright, pull up a chair. I’ve been staring at the long-range for Indian River (Southside) and, well, it’s a tough one. We’re looking at a real flat spell stretching out for the next couple of weeks.
Water temp is a balmy 77°, which is a few degrees warmer than usual for this time of year – feels like a warm bath, but that’s the only warmth we’re getting. From September 9th all the way through to the 21st, it’s nothing but “poor surf conditions” across the board. The swell is tiny, barely reaching 3 feet, and the wind is a mess – cross-shore, cross-on, and onshore, making for lumpy, choppy conditions. The energy is weak, maxing out at just 72 (72) on that scale, so there’s just no push. Some of those afternoons with the fresh breeze and the chop would be better for a kite than a surfboard.
The only breather comes on Tuesday, September 22nd. The morning session is glassy, with a clean 2ft swell from the ESE (8 second period). The energy is still only moderate (67), but the glassy surface is a big deal. It’s the only day in the whole 16-day window that’s even called “surfable,” and even then, it’s described as “very ordinary.” The wind picks up again in the afternoon, so you’d have to be sharp.
For a spot that’s usually “fairly consistent,” this is a real bummer of a run. Nothing to do but wait for the next system.
