The Lowdown
Alright, Rusty here. Let’s take a good hard look at what’s on offer.
Honestly, it’s a tough stretch ahead. The Jetty is a very consistent break, but that doesn’t mean much when the conditions are fighting us. For the first week and a half, we’re staring down a string of poor surf days. The wind is a constant problem—mostly cross-onshore, often moderate to fresh, just chopping everything up. The swell is tiny, mostly under 3 ft, with short periods around 6 to 8 seconds, so there’s no real push. It’s a long, flat, bumpy run.
We finally get a couple of cleaner windows around Wednesday the 29th and Thursday the 30th of July. The mornings are where it’s at. On Wednesday the 29th, we’ve got a light north-easterly cross-offshore breeze, which will clean the surface right up. The swell is 3 ft from the SSE at 8 seconds, with a combined energy of 116—moderate, but nothing special. It’s surfable, but very ordinary. Thursday the 30th looks similar: a 3 ft SSE swell, 9-second period, with a moderate cross-offshore breeze from the NNE. The energy is a bit better at 136. These are the only two sessions that look even remotely worth paddling out for, and they’re really just about getting wet rather than scoring.
There’s a glimmer on Monday the 3rd of August. A clean, gentle offshore wind from the NNW, with a 3 ft SSE swell at 8 seconds and a combined energy of 143. That’s the best-looking setup in the whole forecast, but it’s still a long way out. I’d call it promising but not a lock.
After that, it’s back to the doldrums. The swell drops off a cliff, with heights below 2 ft, and the wind is all over the shop. The Jetty is consistent, but it’s not firing. This is a blank run for anything fun. For a spot that’s so reliable, it’s a real bummer, but forecasts can change.
The best call is Monday the 3rd of August morning. If you’re keen, set the alarm for Wednesday the 29th or Thursday the 30th of July mornings, but don’t expect much.
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.
