The Lowdown

Alright, Rusty here. Let's chew the fat on the long-range picture. We've only got one break on the menu, and that's Irmas/Leftpoint.

To be straight with you, the next 16 days are a bit of a slog. There's some proper size coming, but the wind is going to be a pain in the neck for most of it. The water is a warm 80°F, which is right where it should be for this time of year, so no drama there.

We start Friday the 24th of July with a messy 7ft ENE swell, but that 25 mph cross-shore wind is going to chop it to bits. Leave the board in the car. Saturday the 25th is more of the same, though we get a weird little window Saturday afternoon where the swell drops right off to 3ft, but it swings to a long-period 18-second SSW groundswell. The wind is still a fresh cross-shore though, so it's lumpy. The energy is moderate, not worth the drive.

Sunday the 26th keeps the lumpy, cross-shore vibe going with a mix of small swells. The energy picks up a bit by the afternoon, but the 4ft wave is still a mess. Monday the 27th and Tuesday the 28th see the swell building again. Tuesday afternoon is the first real sign of life: a 10ft E swell with a 13-second period, and the wind finally goes cross-offshore from the NNE at 19 mph. The combined energy jumps to 3274, which is strong. The report says "clean," and that's a huge win. This is the standout for the whole run. The size is 10ft, so this is strictly for the experienced crew. It's a reef break, so that long-period groundswell will wrap in nicely. Crowds are listed as "sometimes," so expect a few heads out.

Wednesday the 29th of July is the other gem. Morning brings an 8ft ENE swell and a gentle 9 mph cross-offshore breeze, with strong energy at 1728. By Wednesday afternoon, it drops to 6ft with a 9-second period, but the wind is a light 6 mph cross-offshore. The forecast says "expect very good surf conditions." That's the cleanest window of the whole 16 days. The energy is moderate, but the quality will be top-notch.

After that, it's a slow fade. From Thursday the 30th of July right through to the end of the first week of August, the wind turns back to a messy cross-onshore or strong cross-shore, and the swell gets chopped up again. The 8th of August shows another big 10ft ENE swell, but with a fresh cross-shore wind, it's going to be a bumpy, lumpy mess. Not worth it.

So, the only real swings you've got are Tuesday the 28th and Wednesday the 29th of July. Tuesday is the one for power and size, but Wednesday is the cleaner, more fun option for the intermediate surfer. The rest of the 16 days, you're fighting the wind.

Rusty.

Information about the Irmas/Leftpoint Surf forecast

The above surf forecast table for Irmas/Leftpoint provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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.
