The Lowdown

Alright folks, Rusty here. Let’s get straight into it. The next 16 days are looking pretty grim for Irmas/Leftpoint. I’ve got to call it how I see it, and there’s nothing in the cards that’s going to get the heart rate up. We’re stuck with a persistent easterly wind that’s going to keep the surface messy and ugly.

The water temperature is sitting at 80°F with an anomaly of just 0.9°F, which is pretty much average for this time of year—nothing unusual there.

Right now, on Saturday, August 1st, we’ve got a 12 ft easterly swell, but it’s coming with a 28 mph cross-onshore wind. The combined energy is high at 1657, but the wind is just destroying it. It’s a mess. That theme continues through Sunday and Monday—big numbers on the energy scale (1157 on Sunday, 598 on Monday), but the wind is never clean. It’s cross or cross-onshore, medium to strong, all from the ENE. The short period of 8 seconds means the waves are weak and lumpy. Not worth paddling out.

By Tuesday, August 4th, the swell drops to 6 ft from the east, but the period stretches to 11 seconds. That’s a bit more groundswell character, but the wind is still a moderate cross-shore. The energy is moderate at 731, and the rating is a lowly 1/10. It’s marginal at best, and the tide could be a factor. This is the closest we get to a “maybe” all week, but it’s not good.

From Wednesday, August 5th, through to the end of the second week, it’s a long, bleak stretch. The swell drops to 4 ft and below, with periods all over the place—short 6s, then a weird 14s from the SSW on the 6th, then a 16s from the SSW on the 10th. That long-period stuff might sound good, but the wind is still cross or cross-onshore, and the energy is low to moderate (316 to 662). The wave state is always described as “poor” or “lumpy.” There is nothing here that’s going to produce a clean wave.

The second week sees a couple of spikes in energy, like on the 12th of August, when a 4 ft south swell at 17 seconds pushes the energy to 1089, but the wind is a fresh cross-onshore. It’s still messy. On the 15th, we get another 8 ft+ easterly swell with 28 mph cross-onshore wind—again, just a blown-out mess.

The absolute standout? There isn’t one. There is no clean window. The only break on offer is Irmas/Leftpoint, and it’s a reef break that needs clean conditions to work. The prevailing wind is from the ENE, and it’s a cross or cross-onshore the entire 16 days. The swell direction is from the east, which is fine for the break’s optimum ESE direction, but the wind is the killer.

Honestly, with this much wind and the beach setup, this looks more interesting for kite surfing than paddle surfing. Don’t bother with the surfboard. Forecasts can change, but right now, it’s a long 16-day blank run.

Rusty.

A general guide to surfing at Irmas/Leftpoint can be found by selecting the local surf guide option on the grey menu. Our Irmas/Leftpoint surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. 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.
