The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next 16 days for Indian River (Southside) are a real struggle. We’re looking at a long, dry spell with hardly any surf worth paddling out for. The only window that gets a nod is a brief pulse around Wednesday the 22nd, but it’s not exactly a day to call in sick for.
The pattern starts flat and stays that way. From Saturday the 18th right through to Tuesday the 21st, it’s tiny, weak, and messy. Winds are all over the shop, mostly cross or onshore, and the swell is barely a ripple. You’ll see waves of 0.7 ft to 3 ft with periods under 8 seconds, and the combined energy is a pathetic 19 to 59 – that’s weak, no energy at all. The water’s a touch warmer than normal at 77°, but that’s the only good news.
Then on Wednesday morning the 22nd, we get a little spike – a south swell bumps up to 6 ft with a period of 8 seconds. The combined energy jumps to 695 (moderate), and we’ve got a clean, cross-off wind from the WSW. That’s the best we’ll see, but it’s still only a 2 out of 10 as far as quality goes – marginal at best. The wind is good, but that short period means the waves will be a bit junky and fat. It’s a beach/jetty setup, so it’s not going to hold that shape well. This is for advanced surfers only – 6 ft is too big for beginners. The afternoon cleans up even more with a NW wind, but the swell drops to 4 ft and energy halves.
After that, we’re back to the grind. Thursday the 23rd through to Sunday the 2nd of August is a desert – tiny waves (0.7 ft to 4 ft), mostly onshore or cross-shore winds, and energy readings that barely crack 100. The swell direction is all over the place, from ESE to SE, and the period is short. There’s a day of glassy conditions on the morning of Sunday the 2nd of August, but with only 1 ft of swell from the ENE, it’s just a flat, pretty lake. No power, no push.
So, the honest truth? The only standout is that Wednesday morning the 22nd. It’s not great, but it’s the only thing on offer. Don’t expect much, and keep an eye on the forecasts – sometimes a blank run like this can turn around, but for now, it’s a long wait.
Rusty.
