The Lowdown
Alright folks, Rusty here with a look at what we’ve got on the horizon.
Well, I gotta be straight with you – it’s a grim stretch ahead for the most part. We’re looking at a solid two weeks of flat, weak conditions before anything rideable shows up. For the first thirteen days, from Monday the 7th through to Saturday the 19th of September, it’s almost all "poor surf" with tiny swells and messy winds. There’s not a single standout session in that whole block. The wave energy is pathetic, often sitting in the low double digits (like 27 or 15) – just a total energy desert. You’d be better off finding a lake or a swimming pool.
The only real glimmer comes right at the tail end of the forecast window. On Sunday, the 20th of September, Jetty (Jetty-4 here) finally sees a pulse of energy. We’re talking a 4ft swell from the SSW with a short, 6-second period, combined energy hitting 125 (moderate). The wind finally plays ball too – a moderate offshore NNW breeze. We’re not looking at anything world-class, but after so many days of nothing, it qualifies as "surfable." It’ll be a bit raw and short-period, but the clean conditions from that offshore wind will make it the best session on offer. By Monday afternoon the 21st, the swell bumps up to 4ft from the east, but it’s chopped up by a cross-onshore wind, so that Sunday morning window is clearly the pick of a very ordinary bunch.
For a spot that’s very consistent, having such a blank run is unusual, but this period looks stubborn. Hold tight, forecasts can change.

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.
