Table - best surf conditions forecast for Jetty over the next 16 days.
Alright, Rusty here. Let's take a look at what's on the table for Jetty.
Honestly, the next week and a half is a bit of a tough watch. There's a whole lot of nothing happening for the first few days. We're looking at a real dry spell from Saturday the 11th all the way through to Tuesday the 15th. The swell is tiny, the wind is all over the place, and it's just not worth paddling out for anything. You'll be sitting there bobbing around on a 1ft to 2ft bump with onshore or cross-shore junk. Save your energy.
Now, things get a little interesting on Wednesday the 15th. The morning shows a bit of a pulse from the SW at 4ft, and with a light W cross-off breeze, it's actually clean. The combined energy is moderate at 132, so there's a little push there. It's not going to be pumping, but it's surfable. That afternoon, the size drops off a cliff, so don't get too excited.
The real standout, and the only one worth getting up early for, is Monday the 20th of July. A solid SSW swell rolls in, hitting 6ft overnight. The combined energy jumps to a strong 462, so it's got some real grunt to it. The wind is a moderate NNE cross-off, keeping the face clean. This is a proper jetty wave setup. That 6ft is pushing into the territory where it gets a bit much for beginners, but for the intermediates and up, it's game on. The swell direction is SSE, which is a good angle for the jetty. The afternoon on the 20th is still holding at 5ft with a light ESE cross-on, but the morning is the clear winner.
The rest of the 16-day window thins out again. Tuesday the 21st has some leftover 4ft from the S, but the wind is cross-on and choppy. There's a small window on the morning of Friday the 24th with a clean 3ft and offshore NW wind, but it's a shadow of the Monday session. The 25th has a similar 5ft from the SSE in the morning, but the wind is a light cross-off, so it's ordinary. Nothing else really stands out.
So, the call is simple: if you want a wave, wait for the morning of Monday the 20th. It's the best, and really the only, proper swell in the forecast. The jetty should be handling it well, and with that offshore flow, it'll be clean. Get amongst it.
Rusty.

Information about the Jetty Surf forecast
The above surf forecast table for Jetty provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jetty can be found by selecting the local surf guide option on the grey menu. Our Jetty surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jetty) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
