The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s shaping up for the next couple of weeks.

The overall story is pretty quiet. We’ve got a long stretch of small, windy, or messy conditions ahead, with only a few brief windows where the surf might just be worth a paddle. There’s a gap of several days at the start with no real recommendations, so don’t expect much until the weekend.

The first bit of hope shows up on Sunday the 19th. The wind is set to switch offshore from the NNW, and that’s the main positive here. We’re looking at a modest 3 ft swell from the south, with a period of 7 seconds. The combined energy is moderate (104). The water temperature is 74°, which is a touch warmer than normal for this time of year. Sunday morning looks clean and rideable, but it’s not going to blow your socks off – it’s ordinary but surfable. The afternoon is smaller at 3 ft with the same offshore wind, but the energy drops off (86).

Then we hit a dry patch again. Monday through most of the next week is mostly small, onshore, or just plain poor. The wind is all over the place, and the swell stays tiny.

The real standout, and the only one in this whole outlook, comes on Wednesday the 22nd. It’s a big warning though – this is a serious pulse of energy. The swell jumps to 8 ft to 8 ft from the S and SSW, with a period of 9 seconds. The combined energy is massive (1449), which is strong to very strong. This is not for beginners. It’s only for experts. The problem is the wind is a cross-onshore from the SW, making it lumpy and messy. For a beach break with that much power and cross-wind, honestly, this setup looks more interesting for kite surfing than paddle surfing. It’s a big wave day, but the quality for a standard surfer is poor.

Thursday the 23rd offers a small cleanup with offshore NW winds, 3 ft to 3 ft S swell, but it’s still just ordinary. After that, it’s back to the same story: small, onshore, and poor through the end of the month and into the start of August. There’s a brief moment on the morning of Friday the 31st with glassy conditions and 3 ft S swell, but it’s small and the energy is weak (82). It’s surfable, but nothing special.

So, to sum it up: the best on offer is the Sunday the 19th morning session for clean, small waves if you’re desperate. The only real power day is the 22nd, but that’s a messy, expert-only affair with strong cross-winds. The rest of the 16 days are mostly a write-off.

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.
