The Lowdown

Alright folks, Rusty here. Let’s talk about what’s on offer for Irmas/Leftpoint over the next couple of weeks. Straight up – this is a lean stretch. The reef’s fairly consistent, but the wind and swell aren’t playing nice for most of it. There’s a real dry spell at the start, then a few days that might get you out, but nothing that’ll have you calling in sick.

The first recommendation doesn’t show up until Saturday 25 July. Before that – from Sunday 19 July through Friday 24 July – it’s all poor surf conditions: cross‑shore winds, lumpy chop, and messy lines. No point paddling out. That’s a solid six‑day gap with nothing to ride.

Saturday 25 July morning brings a slight improvement. You’ve got a 6.6 ft swell from the ENE, with a short 8‑second period, and a fresh cross‑shore breeze that keeps things lumpy. The combined energy is strong (1136), but the quality is still marginal – score of 1 out of 10. Afternoon drops to 3.0 ft SSW groundswell, so not much better.

Sunday 26 July morning sees a 3.6 ft E swell with a very long 17‑second period – that’s proper groundswell. Combined energy is strong (1604). But the wind is still cross‑shore from the ENE at 30

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.
