Alright, I’m lookin’ at the chart for the next 16 days, and I’ve gotta be honest with ya – it’s a rough stretch. The only spot I’ve got on the radar is Irmas/Leftpoint, and it’s a pretty grim picture for the whole run.
We kick off on Sunday, July 5th, with a tiny 3ft SSW swell pushin’ in, but there’s no joy here. The wind is howlin’ out of the ENE at 25 mph, cross-shore and messy, churnin’ up a lumpy cross-chop. The water’s sittin’ at 80°, which is pretty much normal for this time of year, but that’s the only thing that’s normal about it. The swell energy is moderate, around 903, but with that wind, it’s just a washing machine. Straight-up poor surf, not worth paddlin’ out.
From Monday the 6th through the rest of the window, the swell picks up a bit, but it’s all from the ENE, mostly short-period junk between 7 and 8 seconds, so it’s gonna be weak and wonky. The size hangs between 5ft and 8ft, but the wind stays stuck on that cross or cross-onshore ENE breeze, 19 to 25 mph, keepin’ everything messy and lumpy. The wave energy climbs into the moderate to strong range (up to 1040 at times), but with that wind direction and period, it’s just a choppy, blown-out mess. Not a single session in the whole 16 days gets a clean recommendation.
Honestly, this setup looks more like a kite surfer’s playground than a paddle surfer’s dream. There’s plenty of wind, but for us guys with a fin in the water, it’s a total write-off. The forecast can always change, but right now, there’s nothin’ worth your time.

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.
