The Lowdown

G’day, I’m Rusty, and I’ve been staring at the charts for your patch for the next 16 days. Honestly, it’s a grim stretch for Irmas/Leftpoint. The first few days are a write-off, and there’s a long gap of nothing but poor surf conditions until we finally get a window that’s worth paddling out for. Let’s break it down.

There’s no surf on offer at all on Saturday 25 July and Sunday 26 July – the wind is howling out of the ENE at 22 to 25 mph, with messy cross-shore chop and the combined wave energy is high (1307 to 1470), but it’s all wind-affected junk. You’d be fighting a losing battle. Monday 27 July and Tuesday 28 July are still marginal, with moderate cross-shore winds (15 to 19 mph) and the swell is mostly east-southeast, but the period is short (8 to 13 seconds) and the conditions are lumpy. The energy is strong (1357 to 2939), but the quality is poor.

Now, the standout – and I mean the only real standout in this whole 16-day outlook – is Wednesday morning, 29 July. That’s your moment. The wind goes glassy, almost dead calm out of the WSW at just 3 mph, with a solid 10 ft swell from the ENE. The period is 11 seconds, so it’s a proper groundswell with good energy (2604). The water temp is 80°F, which is about average for the time of year. This is excellent surf, but it’s only for the experienced crew – 10 ft is too big for beginners. The break is a reef, so it’ll handle the long period swell well, but it’s “sometimes” crowded, so expect a few others on it. The optimum swell direction for this spot is ESE, and the swell is coming from ENE, so it’s not a perfect match, but the glassy conditions will make it clean. That is the best on offer by a long shot.

After that, things go downhill fast. Wednesday afternoon turns cross-on, Thursday 30 July through to Sunday 2 August are all cross-shore or cross-onshore winds (12 to 28 mph) with lumpy, messy surf. The swell stays around 5 ft to 10 ft but the short period (7 to 8 seconds) and strong wind make it a total mess. The energy is moderate to strong (650 to 1555), but it’s not worth paddling into. The second week – from Monday 3 August to Sunday 9 August – is a boring stretch of poor surf with ENE cross-shore winds (15 to 22 mph) and weak to moderate energy (283 to 910). The swell is small to medium (3 ft to 8 ft) but the period is short (7 to 13 seconds) and the waves are lumpy. No real standouts in that second week, just a blank run of poor conditions.

Overall, the only true standout is Wednesday 29 July morning. The rest of the 16 days is a long gap of poor or marginal surf. It’s a tough run, but it tends not to stay this poor for long – forecasts can change.

A general guide to surfing at Irmas/Leftpoint can be found by selecting the local surf guide option on the grey menu.

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.
