The Lowdown

Right, listen up. I’m Rusty, and I’m looking at what’s on offer for the next couple of weeks. It’s a pretty tough stretch for the most part, so don’t go getting your hopes up too high. We’ve got one spot to look at, and it’s a long, dry spell before we finally see something worth talking about.

The whole period is dominated by strong, persistent cross-shore winds from the ENE and NE, which are gonna keep the surface chopped up and messy. The water temperature is sitting at 80°, and that’s right where it should be for this time of year, so no surprises there.

The first real chance of anything decent comes on the 18th of August. That’s a long way off, nearly two weeks. For the ten days before that, from the 3rd to the 13th, it’s a complete write-off. The conditions are just poor, with wind ripping across the waves and the swell energy being moderate to strong, but blown out. You’ll see combined energy readings between 275 and 839, but it’s all for nothing with that wind. The swell that does show up is mostly short period, around 7 to 8 seconds, which is just wind swell junk.

Now, on the 18th of August, the morning session at Irmas/Leftpoint is the only real standout. It’s not a big, powerful swell, but for this spot, it’s the one. The wind goes glassy, dead calm. That’s a major positive. The swell is coming from the ENE at 8ft with a period of 8 seconds. Combined energy is 796, which is strong. That’s a solid amount of push. The water is still warm, and the lack of wind will make the reef setup really clean. It’s a fairly consistent spot, but you can expect crowds there sometimes. The swell direction is ENE, and the optimum for this break is ESE, so it’s a bit off, but the glassy conditions will make up for it. This is a reef break, good for intermediate surfers, but that 8ft swell is getting into the territory where it’s better for the more experienced crew. The afternoon sees a light cross-shore from the SSW, which will bring a little bump, but it’s still a much better option than anything else in the previous week.

Honestly, there’s a massive gap in decent surf until that Tuesday morning. It’s a long wait, but when it comes, that glassy session at Irmas/Leftpoint will be worth the patience.

Stay keen, and I’ll see you in the water.

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.
