The Lowdown

Alright, Rusty here. I’m looking at the surf for the next couple of weeks, and it’s looking like a real quiet spell. The swell window is pretty much closed for business, and we’ve got a long stretch of nothing much to get excited about. The whole 16-day window is here, but the first real chance to get out is a long way off, and even then, it’s not going to be anything to write home about.

First off, from the start of the forecast right through the end of July, we’re in a flat spell. The combined energy is tiny, with values like 31 (Jupiter Inlet South Jetty) on the 25th, which is just weak. The swell is a piddly 0.2m to 0.5m, with a short period around 8 seconds. That’s just windswill, and it’s not doing a thing. The winds are all over the place, but the surf is way too small to care about, even when we get a clean, glassy window like Sunday afternoon (26 July) with offshore wind. It’s a flat run, plain and simple. We’re looking at a gap of nearly two weeks with nothing worthwhile.

The one true standout, and I mean the only real chance to get a wave, is on Wednesday morning, 5 August, at the Jupiter Inlet South Jetty. It’s a beach/jetty set-up, and that’s all we’ve got. The water temp is about average for the time of year, nothing unusual. The swell is a tiny 2ft coming from the ESE, with a short period of 4 seconds, so it’s not going to have any punch. The combined energy is a weak 17. But the thing that makes it the best of a bad lot is the wind: it’s glassy, and it’s going to be clear. That means the surface will be as smooth as a mirror. For a spot that’s often crowded, the lack of any real swell might keep the crowds thin, but it’s a jetty, so you can usually find a little peak. It’s not a standout for size or power, but it’s the only clean, rideable option in the whole period. The swell direction is from the ESE, which is a bit off the optimum NE direction for this spot, but with clean conditions, you can still make it work.

Later in the day on 5 August, the wind goes onshore, so that morning window is the one to aim for. The rest of the run into the second week is more of the same: tiny swell, mixed winds, and low energy. For example, 6 August has a glassy morning with a 2.3ft swell, but the energy is still weak at 22. It’s a similar story, just not quite as clean as the 5th. So, to be honest, keep your expectations low. If you’re desperate, the 5th of August morning is your only real shot. Otherwise, it’s a long wait for something better.
