Howdy, Rusty here. Look, I'm not gonna sugarcoat it – the next 16 days at Jupiter Inlet South Jetty are a complete bust for surf. The swell is flat, the periods are short, and the wind is mostly junk for this beach/jetty spot that really wants that NE direction to do its thing. The combined wave energy never even gets past weak (max 66). Water temp's sitting at 86°, about average for this time of year.
From Monday 6th July all the way through Tuesday 21st July, there's nothing worth paddling out for. Swell heights are stuck between 0.3ft and 3ft, with periods mostly a pathetic 4 to 5 seconds – that's not waves, that's bathwater. Winds are cross-on or cross nearly every session, stirring up chop and ruining what little bump there is. A couple of glassy windows pop up – Tuesday 7th July morning is glassy with 0.7ft from the ENE, and Sunday 12th July morning is glassy with 2ft from the SE – but the energy is just 7 and 25, so there's no push behind it. Monday 13th and Tuesday 14th July see clean offshore breezes from the WNW and WSW, but the swell is barely 0.7ft. A few afternoon sessions in the second half have light cross-off or clean conditions, but the swell never breaks 3ft and the energy stays weak.
This is a rough stretch for a spot that's usually fairly consistent and built for advanced surfers. Best advice? Keep the boards in the truck, find something else to do, and remember – it never stays this flat forever around here.
Rusty.

Information about the Jupiter Inlet South Jetty Surf forecast
The above surf forecast table for Jupiter Inlet South Jetty provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jupiter Inlet South Jetty can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jupiter Inlet South Jetty may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
