Updates in hr min s Forecast update imminent
G’day, Rusty here. I’ve gotta level with you—this stretch of the forecast is a proper dud. Over at Irmas/Leftpoint, the next 16 days look like a battle against the wind. The water’s 79°, which is pretty average for the season, so no complaints there, but the surf story is a grim one.
The overall pattern is relentless cross-shore ENE wind, blowing 19 to 25 mph for days, kicking up a lumpy cross-chop that ruins any chance of clean waves. There’s swell energy around—moderate to strong, with values between 222 and 1031—but it’s all short-period (mostly 7 to 8 seconds) junk from the ENE, which doesn’t suit the reef. The only decent direction comes on the 4th and 5th of July, with a long-period SSW to S groundswell, but it’s only 2 to 3 ft, and the wind is still cross-shore. Every session is rated poor, with scores of zero or one.
The only vaguely notable moment is the morning of the 5th of July, with a 7 ft ENE swell and energy at 967, but the period is just 7 seconds and a strong 25 mph cross-shore wind ruins it. That’s not for surfing; that’s for kiteboards if anything. For the rest, it’s small (2 ft to 8 ft) and messy.
Bottom line: there’s not a single good surf option across the entire 16-day window at Irmas/Leftpoint. The break gets swell fairly often, so this run is down to bad wind and poor direction. Things can change, but right now, don’t bother waxing up.

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.
