The Lowdown
Well folks, it’s Rusty here, and I gotta tell ya – this forecast is a tough one. We’re looking at a long, dry spell over the next 16 days at Leftovers/Rightovers. The first recommendation doesn’t pop up until Tuesday the 11th of August, and even then, it’s a real struggle.
For the entire outlook, the surf is just not happening. We’ve got tiny waves, mostly around 0.6 ft or 0.9 ft, with very weak combined swell energy – mostly in the single digits or low double digits, like that weak reading of 30 on the Tuesday afternoon. The wind is a constant factor, blowing cross-off or cross-shore from the east and northeast at 12 to 18 mph most days, which just kills any hope of shape or power.
There’s a long gap in the middle here where there’s just nothing worthwhile. The first few days give us absolutely nothing rideable. By Saturday the 15th, we get some rain squalls and the wind cranks up to 21-25 mph from the NE and ENE, with a bit of lumpy cross-chop – that’s not surf, that’s a washing machine. Surprising that even with the wind going offshore on Sunday afternoon the 16th, the swell is still a pathetic 0.9 ft.
The combined energy stays weak throughout, with the highest reading being just 69 on Wednesday morning the 19th of August – moderate at best, but with that 0.9 ft swell from the SW, it’s just not going to line up. Even though the water temp is a warm 80°F and about normal for this time of year, it doesn’t help the surf.
We see a few more little bumps pop up in the final week, but it’s the same sad story: 0.6 ft or 0.9 ft, short period, weak energy, and always that cross-off breeze. Honestly, there’s not a single standout day in the whole 16-day window. This is a total blank run for Leftovers/Rightovers. If you’re keen on getting wet, you might be better off looking for a flat-water paddle or a kite session, because the paddle surfing is a no-go.
Stay patient, mates. It won’t stay this poor forever. Rusty out.

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 Leftovers/Rightovers 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.
