Alright, Rusty here. Let’s be straight with you – I’ve looked over the next 16 days for the break we’ve got data on, and I gotta tell you, it’s a tough stretch. There just isn’t a single good surf option on offer in this whole window. Nothing worth paddling out for, every single session is flagged as poor conditions. It’s a full-blown blank run from now through to the end of the forecast.

We’re talking about Irmas/Leftpoint, a reef break that’s fairly consistent. But for this whole period, the wind is relentless. From Friday the 10th of July right through to the 25th, it’s a constant cross-shore or cross-onshore breeze, mostly from the ENE or NE, blowing at 18 to 25 mph. That’s going to leave the surface ragged and lumpy with a messy cross-chop. You won’t find a single moment of clean, glassy, or offshore conditions. For a reef break, you need that wind to cooperate, and it just doesn’t.

Swell does come through. Early on, from the 10th to the 13th, we see some 6 ft to 8 ft waves from the ENE. But with a short period of only 7 seconds, that’s weak, wind-driven stuff, and the combined energy is moderate (506 to 796). It’s not the sort of energy that builds proper lines on a reef. Later, from the 15th onward, the swell switches to a long-period SSW groundswell (period hitting 16 to 19 seconds), but the height drops to just 2 ft to 3 ft. That long period (over 15 seconds) means it could shape up nicely on a reef, but without any size to push it, it’s not breaking with any power. The water temp anomaly isn’t provided, so I can’t tell you if it’s warmer or colder than average.

So what’s the call? This is a spot that can pump, but not in these conditions. A blank run like this is fairly normal for the area when the trade winds lock in. Keep an eye on the forecasts – they can change, and it tends not to stay this poor forever. But for now, I’d save the wax and wait for a better window.

Later, 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.
