The Lowdown

Righto, let’s have a proper look at what’s on the table for Irmas/Leftpoint over the next couple of weeks. It’s a reef break that’s fairly consistent, exposed to the ESE, and needs a NW offshore to really clean up. The water temp is sitting about average for this time of year, nothing too wild.

To be real with you, it’s a tough run ahead. The first few days? Messy. Monday the 20th through Thursday the 24th of July are basically a write-off. Strong cross-shore winds and a lumpy cross-chop, with swell heights bouncing between 2 ft and 8 ft but the conditions are just not cooperating. The combined swell energy is moderate to strong (values like 569 to 1423), but with those winds and poor surf quality scores, you’re not gonna get any clean rides. That ENE wind is relentless, and it’s blowing cross or cross-on nearly every session. It’s frustrating because there’s some proper groundswell in there – long 16-second periods on Monday morning the 20th – but it’s all blown out.

There’s a small window that starts to look a bit more hopeful from Sunday the 26th of July. The swell drops slightly to 6 ft – 6 ft, still from the E, and the period stays long (14 to 16 seconds), which means proper long-period groundswell. That’s good for a reef like this – it’ll wrap in and offer some decent shape, but you’ve gotta watch the tide. The rating creeps up to a 1 or 2 out of 10 on those days, which isn’t a stand-out, but it’s the best on offer. The combined energy is still strong (over 1700 up to 2424). If you’re keen, Tuesday the 28th morning might be the pick – winds drop to 12 mph from the NE, still cross-shore, but the swell is 6 ft from the E with a 12-second period. It’s marginal but it’s clean-ish.

After that, it fades again. By the end of the month into early August, the swell drops right off – down to 2 ft – 4 ft, shorter periods, and the wind stays onshore or cross-on. The energy drops to weak (143 – 521). Honestly, there’s nothing in that second week that screams “go now.” It’s flat and choppy.

So, if I’m being straight with you, there’s no true standout session in this 16-day window. The best you’re looking at is a couple of marginal mornings around the 27th-28th of July when the wind isn’t howling. Crowds at Irmas/Leftpoint can be around sometimes, but with conditions like this, you probably won’t have to fight for waves. Still, the forecast can always change – it tends not to stay poor for too long around here.

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.

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.
