Table - best surf conditions forecast for Jetty over the next 16 days.
Alright, Rusty here again. Let’s break down Jetty over the next couple of weeks.
To be honest, it’s a rough 16 days. The models are screaming small, weak, and messy. The combined wave energy barely scrapes into the moderate range, hitting 164 on Wednesday morning July 15th, and even that’s described as "ordinary." Most of the time we’re dealing with cross-onshore wind and chop.
Water temp is 70°F, which is about normal for this time of year.
The only session that’s even worth a mention is Wednesday morning July 15th. There’s a 4ft SSW swell on a 6-second period, with a gentle cross-offshore W wind. That wind will keep the surface pretty clean. The energy is moderate at 164, so there’s a little bit of punch, but it’s a short-period swell, so it’ll be a bit weak and crumbly. Still, if you’re jonesing, you could grab a few.
After that, it’s a long, flat, and choppy grind. From Thursday afternoon July 16th onward, the swell drops to 2ft or less, with cross-onshore winds and low energy readings. Friday morning July 17th has a 2ft S swell with a fresh offshore NNW wind, but at that size, it’s barely breaking.
It’s a tough run. The spot is very consistent, but the quality just isn’t there. Hang tight, the forecast might change.
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.
