The Lowdown
G'day, this is Rusty. Let's be straight with you – the Jetty is looking pretty flat and uninspiring for the next couple of weeks. We've got a consistent spot here that's normally worth a look, but this 16-day stretch is a tough one. There's a big blank run at the start, and honestly, for most of the period you'll be wrestling with weak, messy conditions.
The water's sitting at 73° which is about normal for the time of year, nothing to write home about.
The first real sniff of anything rideable doesn't show up until Wednesday the 2nd of September. The morning's still a write-off, but come Wednesday afternoon we finally see surfable waves with a clean 2 ft swell from the SE, period at 11 seconds. The wind's a light cross-off from the WNW at 9 mph, so it's clean. The combined energy is only 93 though, so it's weak. It's not going to get the heart pumping, but it's something.
From there, it's back to poor surf with clean conditions but tiny waves. The wind stays offshore or cross-off a lot, especially from the 3rd through the 7th, with morning breezes from the N and NE at 16 mph, keeping the surface clean. But the swell is just pathetic – 2 ft to 2 ft from the SE or E, with periods between 6 and 10 seconds. The energy is in the double digits, which is as weak as it gets.
Now, around the 8th and 9th of September, the swell tries to push up. On Tuesday the 8th, we see 4 ft to 4 ft from the SSE, but the period is a short 6 seconds. The wind's cross-off from the W and cross from the SW, so it's clean enough. The energy jumps to 116 and 135, which is moderate. But it's still marked as poor surf conditions. Then Wednesday the 9th brings the biggest swell of the period – 5 ft from the SSE, period 6 seconds, with a moderate onshore wind from the SSW at 16 mph. The energy hits 275 (moderate), but it's choppy and messy. That's a kite-surfing setup if I've ever seen one – too big for the short period junk, and blown out.
The rest of the 10th and beyond is back to tiny, clean but weak conditions.
Look, there's no standout here. If you're desperate, the Wednesday afternoon session on the 2nd of September is your best bet for a clean knee-high wave. The Jetty is a breakwater, and it's exposed to the SSE, which is the direction we're getting everything from. But with the swell energy this low and the period so short, it's just not going to deliver. A blank run like this is normal for the area, so don't lose hope – forecasts can 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.
Jetty is 15 km (9 miles) from Mastic. If you plan a vacation in Long Island New York, look for hotels and other accommodation in Mastic. Mastic has rooms for a wide range of budgets as well as car hire and transport links.
