The Lowdown

Alright folks, Rusty here again, this time in feet and miles.

Let’s cut to it: L Jetty is in for a real dry spell. Starting July 17th, we’ve got nothing but tiny, weak waves – 0.3ft to 3ft, short-period slop, and mostly cross or cross-on breezes. Combined swell energy reads between 14 and 75 – that’s floppy, weak stuff. Don’t bother waxing up for nearly five days.

Then on the morning of Wednesday, July 22nd, we get a bit of a pulse: 5ft swell out of the SSE, period at 9 seconds, combined energy up to 359 (moderate push). Winds are cross-off from the SW at 12 mph, so it’ll be clean. Still, it’s only rated marginal. The afternoon of the same day is your best bet: swell drops to 4ft but you get offshore wind from the W at 16 mph, making for glassy, clean lines. That’s the standout.

After that, it’s back to flatness. From July 23rd through the end of the month, waves hover around 1ft to 3ft, with combined energy mostly under 130. Winds are cross or cross-on. A couple of glassy mornings on the 26th and 28th (ENE and NNW light airs) will look pretty, but with only 1ft of swell, there’s nothing to ride.

One more tiny blip on the 29th of July morning: 3ft, SSE, period 8 seconds, combined energy of 89, with a clean cross-off breeze from the SW at 9 mph. Surfable, but barely.

Water temp on the 17th is about 74°, a touch warmer than average for July.

So the long and short: the only real day to make something happen is Wednesday, July 22nd afternoon. Everything else is flat or close to it. Big gap of no surf from the 17th to the 22nd, then another long quiet stretch. Not the usual, but it’s what we’ve got.

Keep checking back – forecasts shift.

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.
