The Lowdown
Alright, listen up. Rusty here, and I gotta tell you, it's a grim start for Indian River (Southside). The next week and a half is mostly flat, so don't rush down there.
From Sunday, August 9th, right through to the morning of Monday, August 17th, it's a total bust. The waves are tiny, mostly under 2ft, coming from the S or SSE with a short period. The water's a touch warmer than usual at 78°, but that's about it. The combined energy is weak, all in the double digits. You might get a glassy morning on Monday the 10th with a light SW 3 mph breeze, but with 2ft waves and a 6-second period, there's nothing to ride. The forecast just keeps saying "poor surf conditions." It's a real test of patience.
The tide turns on Thursday, August 20th. That morning is our standout. We get a 4ft swell from the SE with an 11-second period. The energy jumps to 332, which is solid. The best part? A light offshore wind from the W at 6 mph. That's going to clean that swell right up into some good-looking peaks. That's the session for the advanced crew to hit. The water temp anomaly wasn't given for that date, but it was warmer before, so it should be comfortable.
Thursday afternoon is still worth it. The swell drops to 2ft from the SE, but the wind holds offshore from the W at 9 mph. The energy is still decent at 215. It won't have the same punch, but it'll be clean. Just remember, this is an exposed beach and jetty, so that 11-second swell might be a bit walled up, but the offshore wind will make it work. This spot can have crowds, so time it right.
After that, from Friday, August 21st through Monday, August 24th, we slide back into a small, ordinary pattern. Wave energy drops right off (53 to 60), and the winds are light or onshore. The 21st afternoon has a glassy 1ft ESE swell, but it's just too weak to be fun.
So here's the deal: don't bother until August 20th. That Thursday morning is your one real window. The rest is a long wait or tiny dribblers. Keep an eye on it, but for now, you've got time to wax your board.
Rusty.
