Table - best surf conditions forecast for Jetty over the next 16 days.
Alright, let’s talk about what’s cookin’ at the Jetty. For the first week and a half, honestly, it’s pretty grim. We’re looking at a long stretch of poor surf from now through about the 18th of July. The swell is tiny and the wind is all over the shop – mostly cross or cross-on, nothing to get your heart racing.
But then, like a gift from the surf gods, things flip right around. The standout is Monday morning, the 20th of July. That’s the day. We’ve got a 7ft south groundswell rolling in with a 9-second period, and the wind goes offshore from the north at just 6 mph. It’s gonna be clean, with that energy pumping hard at 690. The wave report says it loud and clear – expect very good surf conditions.
The Jetty is a breakwater spot that’s super consistent, and it loves a south-east swell direction, which is perfect. With that kind of power and offshore wind, the waves will have some real shape and push. It’s a solid, challenging wave for intermediate surfers – just keep in mind that anything over 8ft is expert territory, so at 7ft it’s big but manageable. The water’s at 74°F, which is a good 5°F warmer than usual for July – that’s a big deal, so you’ll be fine in a shorty or boardshorts. Crowds can show up here, and on a morning like that, you won’t be alone.
The next morning, Tuesday the 21st of July, is also worth setting the alarm. It drops to a 4ft south-east swell, but still with clean conditions and a light north-northeast breeze. The energy is moderate at 203, and it’ll be a fun, easy ride for intermediates and maybe some bold beginners, as long as you respect the size.
Before that, the only little flicker is on Wednesday the 15th of July morning – glassy and a small 3ft south swell, but it’s weak and just surfable, nothing special. The rest is a long, boring wait.
So, bottom line: the first week is a hard pass, but the mornings of the 20th and 21st of July are your golden hours. Get out there.

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.
