The Lowdown
Alright, surfers, Rusty here. Let's have a look at what's on the cards for the Jetty.
It's a bit of a slow start with some real poor conditions hanging around. The water temp is sitting at 71°F, which is pretty much what you'd expect for this time of year, nothing unusual there.
The first real glimmer of hope shows up on Sunday the 26th in the morning. We've got a bump in energy with a combined swell energy of 244, and the wind is coming from the NNE, giving us a clean, cross-off breeze. The swell is a small 4ft from the E, but with that clean wind, it'll be the best of a pretty average run. The Jetty is a breakwater, and it's very consistent, but you'll be sharing it with others as it can get crowded sometimes.
The following week from the 27th through to the 29th is a write-off, with poor conditions, onshore winds, and weak energy. Don't bother.
Then we get another little window on Thursday the 30th. The afternoon session sees a nice jump in energy, with a combined energy of 415. The swell is 5ft from the SSE, with a period of 10 seconds, and it's still clean under a cross-off NNE breeze. The forecast does say it's marginal, but that's the best looking set of waves in the whole outlook. Again, expect company.
The start of August is a mess of strong, cross-on winds and lumpy surf. The period from the 1st to the 6th is mostly poor, with energy levels up and down but the wind just ruining it. The biggest swell of the run hits on Friday the 7th of August, with a 6ft SSW swell and a combined energy of 487, but the wind is a messy cross-shore or cross-on, making it choppy and poor. That's one for the experts, if anyone.
The very last day, Saturday the 8th of August morning, has a brief moment of glassy calm with an offshore NNW breeze at only 3 mph, but the swell is tiny at 2ft with hardly any energy. It's clean, but there's nothing to ride.
Rusty out.

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.
