The Lowdown

Alright folks, Rusty here. Grab a coffee, because this one's a bit of a bum steer for the next couple of weeks at L Jetty. We've got a long, flat spell ahead with barely a ripple worth paddling for.

Honestly, the outlook is grim for the near future. We’re looking at a solid stretch of poor surf conditions that just won’t let up. The combined swell energy is weak, sitting in the 20s and 50s for most of the run, with tiny wave heights. For the whole first week, from Saturday the 22nd right through to the end of August, it’s all about knee-high slop at best. The wind is all over the shop – cross-on, onshore, and choppy – so the surface is going to be a mess. The water temp is about average for this time of year, but that’s the only thing that's normal.

There's a flicker of hope on Monday the 31st of August. We get a burst of long-period energy (19 seconds!) from the ESE, but it’s only 0.7 ft. The wind goes clean cross-offshore from the SW, so the surface will be glassy, but with that kind of tiny swell, you're basically just floating. Tuesday the 1st of September is the same story – clean conditions with a moderate offshore breeze from the NW, but the swell is still too small to do anything with. A lot of energy for a very small wave.

The only spot where the numbers start to look a little more interesting is on Wednesday the 2nd of September. The combined energy jumps up into triple digits to 101, which is a solid boost of moderate energy, but the height is still only 1 ft and the wind is a cross-on mess from the SE. It’s frustrating – you can feel some power in the water, but it’s not coming together.

Forget about beginners in the water for the whole outlook – there is no significant swell over 5 ft. This is a quiet period for the jetty. A blank run like this is more normal for the area, so don't lose hope. Forecasts can change, but right now, leave the board in the car.

Rusty.

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.
