The Lowdown

Alright folks, Rusty here. Let’s get straight into it. We’ve got a long stretch ahead, but the news isn’t great for the lineup. For the entire 16-day window, there’s only one break worth a look, and even that one’s a tough sell most days.

Right now through August 1st and Saturday the 2nd, it’s a write-off. Strong cross-shore winds around 25 mph are blasting a messy, ugly 10 ft swell from the ENE at a short 8-second period. The combined energy is high at 1592 (moderate-to-strong), but the quality is poor, plain and simple. Don’t bother paddling out.

We’ve got a long, quiet gap here. From August 3rd all the way through to the end of the forecast on August 16th, the surf conditions are consistently rated poor or marginal. There’s no standout day, no clean window. The wind stays mostly cross or cross-onshore from the ENE, running 12 to 28 mph – that’s a fresh to strong breeze constantly chopping things up. Swell sizes bounce between 1 ft and 7 ft, but the period stays short, mostly between 6 and 11 seconds, which means weak, sloppy surf. The combined energy values are all in the three-digit range (between 171 and 956), so there’s energy around, but it’s all wind-driven junk with no shape.

The only break is Irmas/Leftpoint (a reef setup). It’s fairly consistent and exposed to the ESE, but the wind never swings offshore or light here. A couple of days in early August (the 4th) see a 5 ft to 6 ft ENE swell with a longer 11-second period, which would normally offer some decent lines, but it’s still being blown out by a moderate cross-wind at 12 mph, leaving the water lumpy. The water temp is around 80°, which is about average for the time of year, so no surprises there. Crowds are possible at this spot sometimes, but honestly, with the conditions, you won’t have to fight for waves.

Bottom line: there are no true standouts in this entire outlook. The best you can hope for is a paddle on the early morning of Tuesday, August 4th, when the 6 ft ENE swell hits that 11-second period, but don’t expect anything clean. This stretch is one of those quiet runs for the area; it’s not unusual to see this kind of blank run when the trade winds lock in. Forecasts can shift, so keep an eye on it, but for now, I’d leave the board in the car.

Stay salty,
Rusty

Information about the Irmas/Leftpoint Surf forecast

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