The Lowdown

Alright, Rusty here. Let’s be real about what we’re looking at for the next couple of weeks at Irmas/Leftpoint.

Honestly, folks, this is a tough outlook. The first proper surf recommendation doesn't actually show up until Wednesday the 29th of July, with a 6ft swell from the ENE, but the wind is a light cross-shore from the NE at 6 mph. The water temp is a balmy 80°, which is pretty much spot-on average for this time of year, so no surprises there. The combined energy of all swells is moderate at 704. It’s a marginal call, and the score reflects that. Not really one to get excited about.

From Thursday the 30th of July all the way through to Monday the 3rd of August, the picture turns pretty ugly. We get a pulse of swell, building from 5ft up to a solid 10ft on the Saturday, but the wind is a disaster. It’s a strong cross or cross-onshore breeze from the ENE, gusting 22 to 28 mph. That’s going to turn any reef into a messy, lumpy, wind-chopped nightmare. The wave energy gets strong, hitting 1592 on Saturday the 1st of August, but with those conditions, it’s unrideable for a paddle board. Honestly, with the 10ft swell and that strong cross-wind, this setup looks far more interesting for kite surfing than paddle surfing. That stretch is a total write-off.

We then hit a dry spell from Monday the 3rd of August evening through to Wednesday the 5th of August, where the conditions are marginal at best, with weaker 5ft to 6ft swell and continued cross-winds. Not worth suiting up for.

The second week, from Thursday the 6th of August, is thin. There’s some small, short-period windswell around 3ft to 5ft, but the wind is consistently on it from the ENE. A long-period SSW groundswell tries to sneak in from the 9th of August, with periods of 17 to 18 seconds, but the swell height is pathetic, only 2ft to 3ft. The energy is still moderate in the 600-700 range, but the cross-shore wind from the ENE ruins any chance of it being clean on this reef. A longer-period swell like that needs an offshore wind to really shine, and we don’t get it. It’s a frustrating wait. The only glimpse of a decent morning is on Wednesday the 12th of August, when we get a brief window of onshore wind from the ESE at 6 mph with a 2ft SSW groundswell (period 13 seconds). It’s marginal, but that’s the closest we come to a clean wave in the second half. The rest of the days are just lumpy, choppy, and poor.

The bottom line: Irmas/Leftpoint has one of those blank runs for the next two weeks. The swell is there in the first week, but the wind trashes it. The second week loses the size and the quality. There’s no standout session here. Sometimes it just goes like that. Forecasts can change, but as it stands, I’d save the wax for another week.

Rusty.

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

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.
