Alright folks, Rusty here, and we're taking a look at what's cookin' at Jetty. It's a breakwater deal, wide open to the south, and it's been a bit of a quiet stretch.
Let's not sugarcoat it: the next few days are a bust. From Friday the 3rd right through to Monday the 6th, the swell is flat-out tiny, maybe 1 to 2 feet, and it's got no period behind it. The wave energy is weak, barely registering. The wind is all wrong—cross-shore, onshore, or just plain messy. The reports all say "poor surf conditions." You're looking at a solid five-day stretch of nothing worth wetting a suit for.
Now, Tuesday the 7th offers a little glimmer. The swell bumps up to about 4 feet from the ESE, with the energy meter ticking up to a moderate level. The period is still short, only 6 seconds, so it'll be a bit soft and won't hold a nice face. But here's the thing: Tuesday afternoon goes glassy. Dead calm. That will make the most of that choppy, short-period energy. It's not gonna be pretty, but it might be surfable if you're jonesing for a paddle. For Jetty, a glassy afternoon is a rare treat.
Wednesday the 8th has a clean, offshore wind in the morning on a 2-3 foot swell, so that’s a short window for a clean little wave.
After that, the outlook gets grim again. Through to the 18th of July, we see some bigger pulses of swell—4 to 5 feet on the 15th and even a 5-footer on the 18th, with moderate to strong energy readings. But the wind is nearly relentless: a strong cross-onshore, blowing 15 to 25 mph and sometimes gusting over 30 mph. That turns the ocean into a lumpy, choppy wind-slop. That's kite-surfing territory, not surfin' territory. The wave quality is just trashed.
The one standout in this whole forecast is that glassy window on Tuesday the 7th. The swell is manageable, the wind is perfect, but don't expect any power behind it. The water's sitting at about 71°, which is a touch warmer than average, so at least it'll be comfortable while you're waiting for those weak little peaks.
Honestly, this is a patch where patience is the best move. Check back with me.
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.
