The Lowdown
Alright folks, Rusty here, looking at the Jetty for the next couple of weeks. It’s a real mixed bag, and honestly, we’re looking at a lot of poor surf conditions. The water’s a touch warmer than normal for this time of year at 72°, so at least it’ll feel nice on the skin while you’re waiting for a wave.
The opening stretch is pretty grim. Saturday the 12th is a write-off with tiny 1ft SE slop and cross-onshore wind. Sunday the 13th morning is a no-go with rain, but by the afternoon we get a brief glimmer. The wind will swing offshore from the NNW, cleaning up a 3ft SSE swell. It’s short period (6 seconds) and the energy is only moderate (101), but it’s the first surfable wave we’ll see. It’s not a standout, but you could get a few grovelly ones at the Jetty.
Monday the 14th and Tuesday the 15th are back to junk – tiny waves and messy wind. The rest of the first week stays flat and poor. There’s a long gap with nothing worth paddling out for.
We get a small window Friday the 18th afternoon with a 3ft E swell and clean, light cross-off breeze. It’s only surfable, not firing, but better than what we’ve had.
The most interesting period is way out there, over a week away. On Monday the 21st, a bigger swell pushes in. We’re looking at a 5ft E groundswell in the morning, with a clean offshore cross-off wind from the NE. The energy is strong (206). The problem is that the wind cranks up to 22 mph, which will blow the top off it. It’s expert-only territory, chaotic and lumpy. The following days see even bigger, more powerful swell (up to 7ft ESE on the 24th with a massive energy reading of 1288), but it’s accompanied by near-gale force winds. This setup is more interesting for kite surfing than paddle surfing unless you’re a seasoned pro looking for a beatdown. The conditions are just too raw.
All in all, nothing here is a true standout. If you’re desperate, the cleanest but small windows are Sunday 13th afternoon and Friday 18th afternoon. Everything else is a lesson in patience.
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.
