The Lowdown
Alright folks, it's Rusty here. Let's get real about what's coming up at Jupiter Inlet South Jetty (Florida).
First up, the water temp is sitting at a warm 87°F, which is about average for this time of year. But the main story? There's just nothing on the cards. We're looking at a full 16-day stretch of poor surf conditions. From Sunday the 16th right through to Monday the 31st of August, every single morning and afternoon session is a write-off. You'll see tiny, weak swells barely cracking 2 ft, with combined energy figures that are all in the low double digits or even single digits – the highest I see is 36 (weak energy). That's just not enough to push any decent waves through.
The winds will offer some clean moments, especially on the mornings with a light offshore or glassy conditions, like Monday the 17th, Tuesday the 18th, and Wednesday the 19th. But with next to no swell, that clean surface is just a flat, smooth ocean. It's a bloody tease. The swell direction is all over the place too, mostly from the ENE or ESE, which is okay for the jetty's exposure, but the size is just pitiful. For a break that's fairly exposed, it's a total bust.
There's a bit of a bump in the combined energy towards the end of the month, but it's still only in the 18-30 range, and the swell heights stay under 2 ft. The wind also gets a bit more onshore and stronger, adding chop to the mix. Even the cleanest glassy morning on the 20th of August only has 0.7 ft of swell and 6 units of energy. It's a bummer, but this happens. For an advanced spot like this, when it's flat, it's flat. Honestly, with the stronger onshore winds later on, the setup might look more interesting for kite surfers than paddle surfers.
Keep an eye on the charts, but for now, the board stays on the rack.
Rusty.
