The Lowdown

Alright folks, Rusty here. Let's get into it.

Well, I gotta be straight with you – we're looking at a pretty grim stretch ahead. The Jetty is the only spot on the cards for the next 16 days, and honestly, it’s not giving us much to work with. We’re staring down the barrel of a long, quiet run with next to no decent surf on offer for the better part of the next week and a half.

The water's sitting at a warm 75°, which is a couple of degrees above what's normal for this time of year. Feels nice if you're just floating around, I guess.

The trouble starts now. From Saturday the 22nd right through until the end of August, it’s a write-off. We’ve got tiny, weak swells with energy readings barely cracking 100 – mostly in the 30s and 40s – and the wind is all wrong. That short-period, 1ft to 2ft slop is getting chopped up by onshore and cross-shore breezes. It’s not surfable.

We get a tiny glimmer on Saturday the 29th. The morning sees a light offshore wind from the NW, and a 3ft S swell with a 7-second period showing up. Combined energy is only 91, so it’s weak, but for a moment there it’s the only clean window we see. Conditions are described as "surfable but very ordinary," so don't get your hopes up too much. The afternoon stays clean with a light cross-off breeze, but the swell fades a bit.

Then it’s back to the doldrums. Sunday the 30th, Monday the 31st, and into the first of September are all messy or blown out. There’s a big jump in period to 17 seconds on the Monday afternoon, but it’s only 0.7ft of swell with a strong cross-onshore wind – that's pure wind chop, not a wave you want to paddle out into.

The most promising day in this whole outlook is Wednesday the 2nd of September. A morning session looks like the standout. The Jetty will see clean 3ft SE groundswell, coming in at a 12-second period. The combined energy jumps to 213, which is the first time we see moderate energy in the whole forecast. A light offshore breeze from the west will keep the faces glassy. This is easily the pick of the entire 16 days, but it's a long way off, so treat it as a hopeful rumour for now. The afternoon gets a bit messy with a side-shore wind.

After that, the swell tries to hang around into Thursday and Friday the 3rd and 4th, with waist-high sets possible but the wind stays onshore, making it choppy and uninviting.

Honestly, for the first week and a half, you might be better off not even looking at the surf report. The wind and swell aren't lining up for anything fun. If you’re desperate for a paddle, that Saturday the 29th or Wednesday the 2nd are your only real shots, and Wednesday the 2nd is the one to circle on the calendar.

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.
