The Lowdown
Alright, let’s see what we’ve got here. To be honest, mate, it’s pretty flat out there. The entire 16-day window is looking like a write-off for any proper waves at Jupiter Inlet South Jetty. There just isn’t any surf worth paddling out for. The first record we see is on Thursday the 23rd of July, but that’s a tiny 2ft east-northeast wind swell with a short period of 4 seconds and an onshore breeze – it’s all messy. That sets the tone for the whole stretch.
Through to the end of July and into the first week of August, the swell height barely ever pushes past 2ft and the period mostly sits at 8 seconds or less. The combined wave energy is weak – mostly in the single or low double digits, like 14 on the afternoon of the 23rd and 28 on the morning of the 24th. The wind is often onshore or cross-onshore, adding chop. There are glimmers of offshore wind here and there, like Sunday morning the 26th with a gentle offshore from the west, but the swell is still just 1ft and weak – it’s not enough to surf. The same goes for Monday morning the 27th, Wednesday the 29th, and a few other days where the wind cleans up, but the swell just doesn’t have any push.
Going into early August, it’s more of the same. The swell is tiny and the wind is mostly cross-onshore or onshore. By the 7th of August, the Friday afternoon session is down to 0.3ft with an onshore breeze – you’d be better off swimming.
Water temp on the 23rd is 86°, which is 1° above the long-term average – that’s pretty normal for this time of year. Nothing unusual there.
But honestly, there is nothing to recommend here. If you’re looking to surf, this stretch is a bust. It’s a tough run, but for this area, a blank spell like this isn’t unheard of. Forecasts can always change, but the way it’s sitting now, leave the board at home.
