G’day, Rusty here. Well, I’ve had a good look at what’s on the cards, and I gotta be straight with you—it’s a tough stretch ahead. The only break we’ve got any data for is Irmas/Leftpoint (reef), and honestly, it’s looking pretty grim for the whole 16-day run. We’ve got a solid block of poor surf conditions from Monday 6 July right through to Tuesday 21 July, and that’s a long, frustrating gap without a decent wave in sight. The pattern is consistent, but not in a good way—just day after day of messy, cross-shore wind and lumpy, chop-ridden surf.
From Monday 6 July morning we’ve got a 8 ft swell from the ENE with a short period of 7 seconds, and the combined wave energy is moderate at around 974. But with a strong cross-shore breeze at 25 mph and a "strong cross-shore with messy cross-chop" description, it’s just a washing machine out there. That setup’s more interesting for kite surfing than paddle surfing. This same ugly story repeats morning and afternoon through Tuesday 7 July (with combined energy between 793 and 1030), and into Wednesday 8 July when the wind swings slightly cross-on, but still strong at 25 mph. Swell heights stay between 6 ft and 8 ft, periods are short at 7–8 seconds, and it’s all labelled "poor surf conditions."
Thursday 9 July through to Sunday 12 July doesn’t get any better. The wind drops a notch to a fresh breeze at 22 mph, but it’s still cross-shore or cross-on, and the description stays "fresh cross-shore with lumpy cross-chop." Swell hangs around 5 ft to 7 ft, all ENE or NE, periods never getting above 8 seconds. Combined energy dips a bit to between 386 and 711, but it’s still not enough to make up for the poor quality. Then Monday 13 July to Tuesday 14 July is more of the same—clear skies, fresh cross-shore wind, and lumpy waves up to 7 ft.
Now, there’s a brief change on Wednesday 15 July. The swell drops right down to 2 ft, but it swings to the SSW with a very long period of 18 seconds. That’s a groundswell, and at a reef break like Irmas/Leftpoint, that long-period energy could peel nicely—if the winds were offshore. But they’re not. We’ve still got a fresh breeze at 22 mph coming from the ENE, creating a cross-onshore mess and a "fresh cross-onshore and lumpy" description. Combined energy is weak at 393–395. So even though the swell direction (SSW) is close to the optimum ESE, the wind just ruins it. That’s not a goer.
From Thursday 16 July through to Tuesday 21 July, it’s back to the same bad script: ENE swell of 5 ft to 7 ft, short periods of 7–8 seconds, combined energy between 488 and 664, and a fresh cross-shore wind at 19–22 mph. Nothing changes—still "poor surf conditions" across the board.
So here’s the bottom line: there’s no standout session in this whole forecast. The one and only break in the guide is a fairly consistent reef that usually works on an ESE swell, but we’re getting ENE wind and swell the whole time, and the wind never goes offshore. It’s a blank run. But don’t lose hope—forecasts can change, and it tends not to stay this poor for long around here. Keep an eye on it, but for now, leave the board at home.
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.
Irmas/Leftpoint is 15 km (9 miles) from the city of Kailua. If you plan a vacation in Oahu, look for hotels and other accommodation in Kailua. Kailua has rooms for a wide range of budgets as well as car hire and transport links.
