Alright folks, Rusty here. Let’s have a look at what’s on the cards for Irmas/Leftpoint over the next couple of weeks.

Right off the bat, I gotta be honest with you – this is a tough stretch. We’re looking at a real dry spell for the first two weeks, with nothing but "poor surf conditions" stamped all over the forecast. The water temp is sitting at a warm 79°, which is pretty much bang on average for this time of year, so at least it’ll be nice to be in the water, even if you’re not catching much.

Starting Sunday the 12th, we’ve got a messy ENE swell around 7 ft, but it’s short-period slop at 8 seconds, and a strong cross-shore wind of 25 mph is just tearing it apart. The combined energy is moderate (470), but the wind is making it a total washout. This same pattern just drags on all of next week. Monday the 13th sees a similar vibe – 6 ft ENE swell, still cross-shore winds, still lumpy. The energy bumps up a bit (736) but it’s all for nothing with that wind. Tuesday through Friday is more of the same: chest-high slop, cross-shore or cross-onshore breezes, and a chop that’ll have you cursing your paddle.

We even get a weird little pulse on Wednesday the 15th afternoon – 2 ft from the SSW with a 14-second period, but it’s rain-showers and cross-onshore, so it’s a no-go. The energy is moderate (320), but the conditions are just poor.

The weekend of the 19th and 20th doesn’t offer much relief either. More ENE windswell, still cross-shore winds, still lumpy. The energy levels are moderate to strong (361 up to 659), but it’s all wind and chop. By the 22nd, the swell picks up a bit to 5 ft-6 ft from the ENE, but with short periods of 6-7 seconds and fresh cross-shore winds, it’s just gonna be a bumpy, blown-out mess.

Now, here’s the standout. After a painful two-week wait, things start to look a little more promising on Monday the 27th. We get a period of cleaner conditions. The morning sees a 3 ft E swell with a proper 15-second period, and the wind drops to a gentle 9 mph cross-shore, bringing the energy up to 961 (strong). It’s still only a "marginal" call, but it’s the best we’ve seen. Then, Monday afternoon is the real gem: a 3 ft SSW groundswell with a 15-second period, combined with a light cross-offshore breeze from the NNE at 12 mph. The energy is still strong (907), and the wind description says "clean." This is your window. For a reef break like Irmas/Leftpoint, that long-period SSW groundswell arriving with clean, offshore wind is a recipe for some proper, lined-up waves. It’s not huge, but it’ll be your best shot at a decent session in the whole 16 days.

So, to sum it up: a long, frustrating gap with no real surf until the very end of the period. The one standout is Monday afternoon the 27th of July. Mark it on your calendar, but don’t hold your breath until we get closer.

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.
