The Lowdown

Alright, Rusty here. Let's get stuck into this one.

Alright, truth be told, the outlook for the next 16 days is a bit of a tough one to swallow. We’re looking at a long stretch of very small, weak swell and a lot of onshore wind. The main break on offer is Jetty, a breakwater setup that's very consistent and exposed to the south. The water temp is sitting about normal for this time of year at 72°, so nothing to worry about there with the rubber.

The first real chance to get wet is Thursday afternoon, July 30th. We’ve got a small 3ft SSE swell pushing in with a short period of 8 seconds, but the combined energy is weak (163). The wind is a cross-off from the NNE at 9 mph, which will keep it clean enough, but the "poor surf conditions" note tells you it's not going to be anything special. You might get a few, but it’s a scratch session.

Friday morning, July 31st, is actually the standout of the whole run. The swell drops a touch to 3ft from the SSE, and the period stretches to 9 seconds, giving it a bit more shape. The combined energy is moderate (104). The real winner here is the wind: glassy as a mirror, 3 mph from the south. The wave comment says "surfable waves but very ordinary conditions" but with that glass off, it’s the best you’ll see. Get on it early because it falls apart.

After that, it’s a desert. From Friday afternoon, July 31st, right through to the end of the first week, it’s a brutal mix of onshore winds and tiny swell. The wind swings cross-on from the SSW or S, and the swell height sits between 1.0ft and 4ft, but the period is short and the energy is low. Even Monday afternoon, August 3rd, when the swell bumps to 4ft from the S with a period of 7 seconds and energy of 225, the wind is a fresh 22 mph cross-on from the S, making it a total write-off. That setup looks more interesting for kite surfing than paddle surfing.

The second week offers no real relief. It’s the same story: small SE to S swell, periods often under 8 seconds, and persistent cross-on winds from the SSW. The only glimmer is Sunday morning, August 9th, we get a clean 2ft S swell with an offshore wind from the N at 9 mph. But it’s weak, and the wave comment is "poor surf conditions." Monday morning, August 10th, is glassy again with a tiny 2ft SSW swell, but the energy is just 65. It’s incredibly average.

The bottom line is this: the only real window is Friday morning, July 31st, with the glassy conditions at Jetty. Everything else is a fight against the wind and a lack of push. It’s a tough run, but forecasts can change, so keep an eye on 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.
