The Lowdown
Alright, this is Rusty. Let me break down what we’ve got coming up at Jetty for the next couple of weeks.
Honestly, it’s a pretty grim stretch for paddle surfing. The first few days are a mess of onshore and cross-shore winds, with the swell either too small or too short-period to make anything decent. The combined energy is weak, often under 100 (57), and the period is a short, weak 5 to 6 seconds. It’s just not worth getting wet.
The pattern holds through the end of July. The best you’ll get is a couple of mornings with clean conditions, but the swell is tiny – around 3ft – and the energy is still low (93 on the 31st). That’s surfable for a longboard or a foiler, but it’s not going to make you smile.
Looking into the first week of August, there’s a slight bump. The combined energy climbs into the moderate range (203) on Monday the 3rd, with a little more period (9 seconds) and a clean, cross-off wind from the NE. The swell is still only 3ft from the S, so it’s not a classic, but it’s the only window in the whole 16 days that actually says “expect good surf conditions.” That’s your best bet, but keep expectations low. After that, it’s back to small, choppy, and poor.
There’s a 4-day gap from the 30th of July to the 3rd of August where things are just ordinary, then another run of poor surf after the 3rd. No standalone standout here; the whole period is about waiting for a better swell.
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.
