The Lowdown

Alright lads, Rusty here. Let's break down this forecast.

I gotta be honest, the next week and a half is a bust. The wind is howling out of the east-northeast at a steady 20-25 mph, and it's cross-shore all day. That's gonna churn the ocean into a lumpy, choppy mess. We're looking at a long stretch of poor surf conditions before things finally turn. The water temp is 80°, which is just about average for this time of year, so you won't be shivering while you're getting blown off your board.

The first real ray of hope hits on July 28th. We get a moderate breeze from the northeast at 16 mph, turning cross-offshore, which is a huge improvement. The swell is 6 ft from the east with a 13-second period. That's proper groundswell, and the wave energy is strong at 1318. This is the cleanest we'll see it, and it's the standout of the whole 16 days. Irmas/Leftpoint (reef) is the place to be. It's fairly consistent, and that long 13-second period will wrap nicely around the point. Expect crowds there, as it's a popular spot and the conditions will be the best of the lot.

The day before, on July 27th, is a bit of a tease. The swell is similar, around 6 ft from the east with a 15-second period, and the wave energy is very strong at 1941. But the wind is still a fresh 19 mph cross-shore, so it's a borderline call. Worth a look, but not the full package.

After that, the wind swings back to the east-northeast and cranks up again, killing the surf. There's a tiny window on July 30th with a light breeze, but the swell is only 3 ft from the east-northeast with a weak 9-second period. The energy is a measly 214. Not worth paddling out for.

Bottom line: mark your calendar for July 28th. July 27th is a maybe. The rest of the 16 days is a no-go with that relentless wind. It's a rough patch, but the forecast can change, and this spot has real potential when the wind eases up.

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.
