The Lowdown
Alright folks, Rusty here. Let’s break down what Surfside Jetty is looking like over the next couple of weeks. I’ll level with you – it’s a quiet run.
Overall, the pattern is pretty flat and uninspiring. We’ve got a big gap at the start with no real surf on offer. From now until the early hours of Wednesday, 26th August, there’s just nothing worth getting wet for. The energy is weak and the wave quality is poor.
Moving into Wednesday the 26th, we finally see a pulse. A south swell pushes in around 4 ft to 5 ft, with a period of 13 to 14 seconds. The combined wave energy is moderate, hitting around 786 to 836. That’s something to look at, but conditions are still marginal due to the tide and cross-onshore wind. Thursday the 27th morning keeps that south-southwest swell at 4 ft, but it’s a bit cleaner with light cross-onshore winds, and the energy is still moderate (639). Still only a borderline call.
Friday the 28th morning offers a small south-southwest swell of 3 ft, 12-second period, with energy at 493. Light winds keep it semi-clean, but it’s still marginal. In the afternoon, a longer period 19-second swell at 2 ft shows up (energy 540), but the wind is onshore and the quality is poor.
Over the weekend and into next week, not much changes. We’re looking at small pulses of swell around 2 ft to 3 ft, mostly from the south-southwest, but winds are often onshore or cross-onshore. The energy stays moderate, but the quality is either poor or marginal. Saturday the 29th morning is about as clean as you’ll see – a 3 ft south-southwest swell, 17-second period, near-calm wind (3 mph), with moderate energy (594) – but it’s still a stretch to call it good.
The best bet in this whole outlook? Honestly, the standout window is Wednesday the 26th. The swell is a touch bigger, around 5 ft from the south, with a 14-second period. The wind goes offshore in the afternoon, so you might find a clean wave on offer. Combined energy is strong (836). It’s not huge, but for this stretch, it’s about as good as it gets. Expect some crowds – this spot can get busy.
Water temperature is about average for the time of year, nothing unusual.
I’ll be honest, there’s very little consistency to get you excited. This is one of those blank spells that can feel normal for the area. Keep an eye on the updates – forecasts can change.
Rusty.

Information about the Surfside Jetty Surf forecast
The above surf forecast table for Surfside Jetty provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Surfside Jetty can be found by selecting the local surf guide option on the grey menu. Our Surfside 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.

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 Surfside 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.
