Right then, let’s have a look at what’s on offer.
To be straight with you, the next two weeks are a bit of a struggle for surf around L Jetty. We’ve got a long stretch of very small, poor-quality swell coming in, and it’s going to be a real test of patience. The water temp is sitting at 72°F which is about normal for this time of year, so at least it’s not freezing.
The first real chance of anything surfable doesn’t show up until early on Wednesday the 22nd of July. The swell is coming from the SE at 2ft with a period of 8 seconds, and the combined energy is weak at just 63. The key here is the wind – it’s glassy, dead calm. That’s a major positive. It’ll be tiny, weak, and clean. For a patient surfer on a longboard, it’s the best of a bad bunch, but honestly, it’s still pretty ordinary. The swell direction is ESE, but the optimum for this spot is also ESE, so at least the angle is right.
The rest of the period is a write-off. We’ve got days of cross-shore and onshore winds, and the swell barely tickles 2ft. The 20th and 21st of July see a little bump of energy – 4ft on the 20th morning from the SSE with a combined energy of 186 (moderate), but the wind is cross-shore, and the quality is poor. It’s just messy.
Later on, the 26th and 27th of July show some promising offshore winds from the W and WSW, but again, the swell is tiny at 1ft. It’s clean, but there’s nothing to ride. It’s a frustrating pattern.
If you’re desperate, the glassy morning on the 22nd is the only window. Otherwise, it’s a long wait. For an area like this, a blank run of this length is pretty normal when the swell drops out.

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