Alright folks, Rusty here. Let’s be straight with you—if you’re looking to paddle out at Irmas/Leftpoint (reef) over the next 16 days, I’ve got to tell you, it’s a tough run. The entire stretch from Thursday the 2nd of July right through to Friday the 17th of July is one long, flatlined stretch of poor surf conditions, and I can’t spot a single standout session worth chasing.
Now, right off the bat, the water’s sitting at a warm 79°F, which is just about normal for this time of year, so no worries there. But that’s where the good news ends. From Thursday morning the 2nd right through the first week, we’ve got a constant cross-shore wind from the ENE, blowing at 18 to 25 mph, which is kicking up lumpy cross-chop day after day. Swell heights bob around 5 ft to 8 ft, but the period is short—mostly 7 to 8 seconds—so it’s just messy, weak, wind-affected stuff. The combined swell energy sits in the moderate zone (between 288 and 991) but it doesn’t matter when the wind’s killing it. Every single session is marked “poor surf conditions.”
Even on Saturday the 4th of July, when a long-period swell from the south rolls in at 21 seconds and 2 ft, the cross-wind from the ENE at 22 mph just ruins it. That groundswell could be something special at a reef or point, but not with that breeze turning it into an onshore mess.
The second week doesn’t get any kinder. From Monday the 6th through to Friday the 17th, it’s more of the same: strong to fresh cross-shore winds, choppy faces, and short-period swell that never cleans up. The combined energy drops into the low-to-mid hundreds, telling you wave energy is weak. There’s a brief moment on Monday the 13th when the wind eases to a moderate 15 mph, but it’s still cross-shore and the swell is only 6 ft at 7 seconds—not enough to save the day.
Honestly, the whole 16-day window is a write-off for surfing at Irmas/Leftpoint. If you’ve got a kite, maybe this one’s for you, but for a paddle surfer, I’d say hang up the board for a bit and wait for the forecasts to change—they often do.
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.
