The Lowdown
Alright, mate, listen. We're in for a bit of a dry spell at L Jetty, to be honest. The next week or so looks pretty grim, with mostly small, messy waves that are really not worth paddling out for. There's a glimmer of hope later on, but we gotta be patient.
The water is a toasty 78°F right now, which is feeling much warmer than normal for this time of year, about 5°F warmer than usual.
Now, the first session that even *looks* like something is Monday the 17th of August. The morning will see a 4ft S swell coming through, but with a real short period of 7 seconds. The combined energy is moderate at 110. The good news is we get clean conditions with a gentle offshore wind from the W. It's surfable, but it's very ordinary, so don't expect any fireworks.
Then we have a bit of a lull again until Friday the 21st of August. That morning there's a 3ft ENE swell, but again, period is a miserable 5 seconds, so it's all chop. Energy is low at 64. The wind is light cross-off from the NW, so it will look clean, but the waves won't have any push.
Finally, we get a couple of days that are a slight step up. Saturday the 22nd of August morning has a 3ft ESE swell, still short period at 5 seconds and moderate energy of 71. With clean conditions and a gentle cross-off wind from the SSW, it's the best option of the run. Again, it's surfable but very ordinary.
Sunday the 23rd of August afternoon also offers a similar story with a 2ft S swell and clean cross-off winds, but again, it's small and unremarkable.
Overall, the standout window is a toss-up between Monday the 17th and Saturday the 22nd. For the size, I’d give the edge to the 17th for the 4ft swell, but the 22nd might have slightly better form. Neither is a classic. Just a couple of sessions to get wet if you're desperate.
There's a fair few days with nothing on offer, particularly from now through the end of this week. It's a quiet patch. For beginners, nothing here gets over 5ft, so it's all manageable if you can find a clean wave, but the lack of power is the real issue.
Rusty, signing off.

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.
