The Lowdown
Alright, Rusty here. Let's have a look at what's cooking.
Honestly, mate, the next couple of weeks are a real mixed bag for Indian River (Northside). We’re looking at a pretty flat start. For the first six days, from Monday the 14th through to Saturday the 19th, there’s next to nothing on offer. You’d be wasting your time. The swell is tiny, wind is all over the shop, and most of the time it’s messy onshore junk. You’ll see wave heights barely scraping 1 ft to 3 ft, with that weak energy. Not worth a look.
Now, here’s something. By Sunday the 20th of September, things finally settle down a bit. We get a little pulse of 1 ft swell coming from the ESE with a period of 11 seconds – that’s a nice long period groundswell, so the shape should be there for a point or river mouth if you can find one. The wind cranks offshore from the W at 9 mph, which means clean, glassy faces. It’s only a 1 out of 10 on the score, but after the dry spell we’ve had, that clean, gentle offshore makes this the most appealing window for a beginner. The water is sitting at 76°, which is much warmer than normal for this time of year – 5° above average, so you can leave the thick suit at home.
The real wild card lands on Monday the 21st of September. A big lump of energy arrives – we’re talking 7 ft to 7 ft from the east with combined energy jumping up to 424 and 582 (moderate to strong). That’s proper size, and it's going to be too big for beginners. The problem is the wind is cross-on and onshore, so it’s gonna be a bit of a messy, lumpy beast. That’s more of a windsurfing or kite-surfing kind of day. Definitely not for the average surfer unless you’re an expert looking for a challenge in poor conditions.
After that, the swell drops back quickly. By the 23rd and 24th, we’re back to small 2 ft to 3 ft waves with clean offshore winds again (SW to NNW) – more morning windows for the patient surfer. The consistency is good, so it’s not completely dead, but the size is underwhelming.
Overall, if you’re desperate, Sunday the 20th is your standout – clean, small, and glassy. If you’re an expert and don’t mind the chop, Monday the 21st has the power but be prepared for a wrestling match. The rest is a long, slow grind of tiny surf.
Rusty.
