The Lowdown

Alright folks, Rusty here. Let’s break it down.

We’ve got a window that starts with a real beauty on Wednesday morning, July 29th, but then it’s a long, frustrating stretch of messy conditions. The rest of the 16-day run is mostly a write-off.

The Good Bit – Wednesday July 29th (Morning)

The standout is hands down the early session on Wednesday morning at Irmas/Leftpoint. This is a reef break, fairly consistent, and it’s exposed to the swell. We’re looking at a clean 7 ft of ENE swell, with a period of 10 seconds. That’s a solid groundswell with proper energy in the water (939). The wind is a light 9 mph from the north, coming cross-offshore, which is going to keep the surface glassy. Water temp is sitting at 80°, pretty much bang on average for this time of year. It’s a proper intermediate-level wave at that size, so it’s got some push but isn’t out of control. The vibe is “very good surf conditions,” and honestly, with that offshore wind, this is the session to chase. Crowds are a possibility here sometimes, so get in early.

The Rest of the Run

After that Wednesday morning magic, the quality drops like a stone. Wednesday afternoon (July 29th) stays rideable at 6 ft, but the wind swings to a cross-shore, and the forecast flags marginal tide issues. By Thursday July 30th, the wind gets cross-on, and things go downhill fast. From Thursday afternoon all the way through to the end of the forecast period on August 13th, the models are showing nearly continuous poor surf conditions. The wind stays up from the ENE, mostly fresh to strong breezes (19-28 mph), creating a lumpy, cross-choppy mess. The swell heights bounce around between 4 ft and 10 ft, but with short periods (mostly 7-8 seconds) and bad wind, it’s just not worth paddling out. The 10 ft days on Saturday August 1st have massive energy (1586), but with 28 mph cross-shore wind, that’s a kite surfer's dream, not a paddle surfer's. There’s a taste of cleaner conditions on August 4th with a longer period of 11 seconds, but the wind is still cross-on, and the quality is marginal at best. Honestly, from July 30th onward, it’s a long dry spell of onshore slop. The very end of the window (August 9th - 13th) switches to a tiny SSW swell, but the wind is still ruining it.

Bottom line: Your only real shot at a good wave in the next 16 days is first light on Wednesday, July 29th at Irmas/Leftpoint. After that, it’s a long wait for the wind to sort itself out.

Stay salty,
Rusty

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.

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.
