The Lowdown
Alright folks, Rusty here. Let’s get into it for Surfside Jetty.
Right off the bat, I gotta be straight with you – this forecast window is a tough one. There’s a whole lot of waiting and not a lot of green lights. The best surf is a long way off, and until then, we’re mostly dealing with small, onshore junk. The first real standout doesn’t show up until the morning of September 7th. That’s about a week-long gap of mostly poor conditions.
Let’s start where we can. Tuesday afternoon, September 1st, is the first flicker of hope. The swell is a weak 3 ft from the south, with a period of 11 seconds. The combined energy is only 300 (moderate), so it’s small, but the wind is glassy with a slight air. That’s perfect for clean conditions. It’s not a world-beater, but for a window that’s mostly poor, that glassy surface is a major win. The water temp is about average for this time of year.
Now, the real highlight. The morning of Monday, September 7th, is the one to circle. The swell jumps to 5 ft from the south, with a 13-second period, giving it some real grunt – the combined energy hits 1364 (strong). The wind is glassy again, with a slight air. That’s the kind of clean, punchy surf that’ll have the lineup buzzing. Keep in mind, this is a long-range call, so it’s promising but not locked in.
Things get a bit wild on Tuesday, September 8th. The morning sees a 8 ft south-southwest swell, but it’s a short-period 11 seconds, and the wind is light cross-onshore, making it marginal. That’s solidly into expert territory size-wise, and the wind isn’t cooperating. By afternoon, a strong 45 km/h cross-shore wind from the southeast absolutely trashes it, making for some nasty cross-chop. Honestly, with that much wind and swell, this setup at a beach break like Surfside Jetty looks more interesting for kite surfing than paddle surfing.
After that, the swell fades fast. The rest of the forecast is mostly small, onshore, and poor. There’s a little bump of 2 ft stuff around September 10th and 11th, but the wind is always onshore or cross-onshore, so it’s not worth getting excited about. The combined energy drops to weak levels (150-520) by the second week.
So, to sum it up: the morning of September 7th is your best shot for a proper session. The Tuesday afternoon glass-off on September 1st is a consolation prize. For the rest, you’re better off waiting for the next system.
Rusty.

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.
