The Lowdown
Alright lads, Rusty here with the outlook for Jetty. Gotta be straight with you – this forecast period is a tough one. We're looking at a long, drawn-out run of poor conditions with only a few small windows of opportunity, and even those are marginal at best.
The first decent look we get isn't until the morning of Wednesday the 29th. Even then, it's a marginal call with small 4ft swell out of the SSE, but the wind is a light cross-shore, keeping things from getting completely blown out. The combined energy (216) is moderate, so there's a little bit of push. It's not going to be epic, but it's the first sign of life after a flat start. The crowd factor is "sometimes" at Jetty, so you might have a few others with the same idea.
Thursday the 30th morning offers a similar story: another 4ft SSE swell with a period of 9 seconds, giving a little more shape, and again a light cross-shore wind. The energy is still moderate at (249). This is probably the pick of the bunch for the first week, but keep your expectations in check.
Friday the 31st morning sees the wind swing cleanly offshore from the NE at 15 mph, which is a major positive. The swell, however, drops right back to 3ft from the SSE. It'll be clean, but small. The energy is weak at (107).
After that, it's a long slog. From the 1st of August right through to the end of the forecast window on the 11th, we're looking at tiny, weak swells, almost all with onshore or cross-onshore winds. The most interesting day in that second week is probably the morning of Saturday the 9th, with a tiny 2ft swell from the east and a light offshore breeze from the NW at 6 mph. It's glassy, but the swell is practically nothing.
Honestly, there is no true standout session here. The best on offer is the morning of the 30th of July. Water temp is sitting around 71°, about average for the time of year.
Keep the board in the car, but don't be surprised if you end up just watching the horizon. This is a period to let the forecast change. Until next time, 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.
