Alright, let’s break this down. For the next couple of weeks, it’s a pretty bleak run of small, wind-chewed waves. There’s a big gap with no real recommendations running right through until the 18th of July. The first thing that might get your attention isn’t until Sunday morning, the 19th, and even that’s not a guaranteed gem.
We’re looking at Jetty. It’s a breakwater spot, exposed to swell, and it’s very consistent, which is about the only positive. The water’s at 74°, way warmer than usual for this time of year, a solid 5° above the long-term average, so at least you won’t be cold.
The best bet is Sunday morning, the 19th of July. There’s a pulse of 8ft swell from the SSW, with a period of 8 seconds. That’s getting big enough to be for the experienced crew only – beginners need to sit this one out. The combined wave energy is strong at 1490. The wind is a gentle offshore from the SSW, but it’s described as only gentle cross-onshore and fairly choppy, so it’s not glassy. It’s a marginal call, but it’s the biggest surf in the window. Sunday afternoon drops to 5ft from the S, with a period of 9 seconds, energy at 404, and a cross-shore wind. It’s rideable but not as clean.
Before that, the numbers are rough. On the 18th, Saturday morning, you get 5ft from the S with a period of 7 seconds, energy at 372, but the wind is a fresh cross-shore creating lumpy chop – that’s more of a kite-surfing day than paddling. The 14th has 4ft from the E with a period of 6 seconds, but the cross-onshore wind is too strong and messy.
Honestly, for the first two weeks, there’s almost nothing worth your time. If you’re really keen, the Wednesday morning of the 13th has a tiny 2ft from the SE with a period of just 4 seconds, energy at 34, and clean conditions from a cross-offshore breeze – but it’s weak and short-period. It’s a waiting game. The long-range call for the 19th is promising, but this far out, don’t put too much faith in it.
Hang in there. The quiet spell won’t last forever – forecasts can shift. But for now, it’s a dry stretch.

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.
