The Lowdown
Alright folks, Rusty here. Let's take a look at what's coming up for Jetty.
Honestly, it's a tough stretch ahead. The forecast shows a long, drawn-out period of small, weak swell and tricky winds. We're not seeing any proper standouts, just a few windows where you could maybe scrape a few mediocre ones. The first real opportunity doesn't pop up until Wednesday afternoon, July 29th.
Wednesday, July 29th afternoon sees the first bit of surf, but it's a mixed bag. We've got a tiny SSE swell coming in at 4ft with a short period around 6 seconds. The good news is the wind goes glassy from the NNW, which is the jetty's offshore direction. This will make the surface clean, but the wave energy is weak, only measuring 99. It's a gamble for a few crumbly, weak waves if you're really desperate. The water temp is 71°, which is pretty standard for this time of year.
After that, we slide into a real flat spell. Thursday the 30th through to Sunday, August 2nd, is all small, poor-quality stuff with onshore or cross-shore winds. You won't want to bother.
Monday, August 3rd, brings a jump in energy, with a combined swell energy of 310 (moderate) from a S swell at 5ft, but the period is a short, choppy 6 seconds. The wind swings onshore and cross-shore, creating lumpy, messy conditions. This would be way too big for beginners and not much fun for anyone else. It's better suited for a kite session than a paddle.
Tuesday morning, August 4th, shows another brief glimmer. The swell drops to a tiny 3ft from the SSE with a weak energy reading of 82, but the wind goes glassy NNW again. If you've got a longboard and just want to trim on some clean, ankle-biters, it might be your only decent chance in the whole window.
The rest of the run, from August 5th out to the 13th, is a desert of tiny swell, short periods, and predominantly onshore or cross-winds. Most days have wave energy below 100. It's one of those blank runs that's pretty normal for this area when the swell windows just don't line up. Keep the board waxed and check back in; forecasts can change.
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.
