The Lowdown
Alright, Rusty again.
Let's break this down: the next 16 days at Indian River (Southside) are pretty flat overall, with no real gems to speak of. There's a long dry spell at the beginning, from the 22nd through the end of August, with mostly small, weak swell and wind that’s not helping. The water temperature is 78°, which is a touch warmer than normal for the season.
The first day with anything surfable is Friday the 28th. Morning brings a 3ft south swell, but it's a short-period, weak swell (5 seconds) with energy at 74. A light offshore wind cleans it up, so you can get a wave, but it's nothing to get excited about.
The real highlight, and really the only one, comes on Tuesday the 1st of September. The morning shows a 5ft east swell with a clean cross-offshore wind and combined energy at 296. That’s decent. Then the afternoon gets even better: a 4ft east-southeast groundswell with a very long 13-second period, clean cross-offshore wind, and strong energy at 775. The longer period means better shape and power. The swell direction lines up well with what this break wants. This is your best shot, hands down. After that, it fades into small, poor conditions through the 6th. If you can get out, make it Tuesday the 1st. The rest is a snooze.
Rusty.
