The Lowdown
Alright, this is Rusty. Let's be straight with you: the next couple of weeks are looking pretty grim for a paddle. We've got a solid 16-day window here, but it's a long, dry spell before anything even starts to look like a wave. The first recommendation doesn't kick in until Saturday the 15th of August, so we're looking at a gap of about 11 days with nothing decent on offer.
For the Jetty, the first real glimmer comes on the morning of Saturday the 15th. The wind is glassy, which is a massive positive, and we get a 5ft southerly swell. The combined energy is moderate at 264, so there's a bit of push behind it. The period is 8 seconds, so it's a short period windswell, but with that glassy surface, it'll be the cleanest it's been all fortnight. It's still small, but for a wave-starved stretch, it's the best on offer. Later that afternoon, it jumps to 6ft from the SSW, but the wind swings cross-onshore, making it messy and marginal. That 6ft is getting into the "too big for beginners" range, especially with the onshore bump.
The only other day that even sniffs a score is the morning of Saturday the 15th. The rest of the window is a write-off. The wind is either cross, cross-onshore, or just straight onshore, and the swell is tiny and weak. We see a lot of combined energy values in the double digits, which is very weak, and everything is rated as "poor surf conditions." There's a moment on the morning of the 13th of August with a clean cross-offshore wind from the north, but the swell is a pathetic 2ft, so it's not worth wetting a suit for.
Honestly, if you're looking at the Jetty, the morning of Saturday the 15th is your only shot. Mark it on the calendar. Other than that, you're better off tuning the radio or finding something else to do. The water temp is sitting at 73°F with a +0.9°F anomaly, so it's about average for this time of year, nothing special.
That's the long and short of it. It's a tough outlook, but that's the way the dice roll sometimes. Keep an eye on the charts, because things can change.
Stay salty,
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.
