Yo, Rusty here. First off, this forecast window is a total bummer for Irmas/Leftpoint. The whole 16-day stretch gets a big fat zero from me.
We kick off Thursday, July 2nd, and it’s just messy. Cross-shore winds howling at 22 mph, and that ENE swell at 6 ft is lumpy and chopped up. The combined energy is moderate at 568, but with that wind, it’s a write-off. This same story repeats day after day. Friday, Saturday, Sunday… wind stays fresh to strong, always cross-shore or cross-onshore, and the swell is poor quality. Even when a long-period SSW groundswell rolls in on Saturday July 4th, with a period of 21 seconds, it’s only 2 ft and that 22 mph cross-shore wind just ruins it. The water temp is a warm 79°, about average for this time of year.
The whole first week is a no-go. Into the second week, from Monday July 6th onwards, we’ve got some size—pushing 7 ft to 8 ft from the ENE—but the period is short, only 7 or 8 seconds, so it’s weak and crumbly. And again, that constant 22-25 mph cross-shore breeze keeps things lumpy and messy. The combined energy stays moderate but the conditions are just foul.
There’s a brief moment on Wednesday July 15th with a 2 ft, 18-second SSW groundswell, but it’s cross-onshore and lumpy, and not worth paddling out for. The same on Friday July 17th with a tiny 1 ft SSW swell, but again, the wind kills it.
Honestly, there’s no standout. The whole 16-day forecast is a gap of poor surf. The winds are just relentless from the ENE/NE, and the swell, when it’s there, is short-period junk or blown out. This setup, with constant cross-winds and short-period, sloppy waves, looks more interesting for kite surfing than paddle surfing.
Keep your board in the car and wait for a change. The forecasts can turn around, but this run is a write-off.
Rusty.

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.
