The Lowdown
Alright, Rusty here, and I'm not gonna lie to you. The next 16 days are a real dry spell for waves at Indian River (Northside). We're looking at a long stretch of weak, wind-chopped conditions. There's a gap of about 10 days with nothing really worth paddling out for, so don't rush.
The water is sitting at 77° right now, which is a solid 5° warmer than usual for this time of year. That's very unusual, so you'll be surfing in a warm bath, for all the good it'll do you.
The only real glimmer of hope is on Thursday, September 18th in the morning. The wind is looking glassy, coming from the N at just 3 mph. That's as clean as it gets. The swell is tiny, only 2ft from the NE, with a short period of 6 seconds. The combined energy is weak (52), so it's marginal, but it's the cleanest window we have. Bring your longboard or a foamie.
Later that same day, the wind turns cross-onshore, and the quality drops off. For the rest of the outlook, it's a messy story of onshore and cross-shore winds, short-period slop, and very poor surf conditions. The few bumps of energy around the 20th and 24th of September are completely blown out by strong onshore winds, making it a total write-off for a paddle. If you're into kiting, those windier days might be fun, but for a surfboard, it's a pass.
Don't stress, though. It won't be this flat and messy forever.
Rusty.
