Alright folks, Rusty here. Let’s be straight up about the next couple of weeks at Irmas/Leftpoint (reef). It’s a pretty bleak outlook, I gotta tell ya. We’ve got a full 16-day window, but honestly, there’s not a single session in this run that I’d be excited to paddle out for. The problem is the wind. It’s locked in from the ENE, which is not offshore for this spot (it needs NW). Instead, we get constant cross or cross-onshore breeze, mostly fresh to strong, which is just messing up any chance of clean waves. The swell is coming from a similar ENE direction, which is the wrong angle for this break – the optimum is ESE – so everything is poor quality.
Looking at the first week, starting Wednesday the 8th of July, it’s a write-off. Swell is around 7 ft to 8 ft from the ENE, which is decent size, but it’s short-period windswell at 7 to 8 seconds, and that combined with the strong cross-shore wind (25 mph) makes for messy, lumpy conditions. Combined energy is moderate, around 500 to 866 (moderate wave energy), but it doesn’t matter when it’s all chop. This pattern just repeats day after day through that whole first week and into the second week. There’s nothing to recommend.
A little bit into the second week, around the 15th of July, the swell drops right off to 2 ft, and we get a brief flash of a very long-period SSW groundswell at 18 seconds, but it’s still cross-shore wind and the energy is only moderate (395). That tiny, long-period swell is going to be too straight to wrap in well here anyway. After that, we get a bit of a bump in ENE swell again on the 18th of July with energy hitting 925 (moderate wave energy) and size around 7 ft from the E, but again, it’s cross-shore wind ruining the surface.
Even the last few days, like the 22nd and 23rd of July, have some E swell with a longer period of 12 to 14 seconds, which is a groundswell, but the wind is still cross-on or cross, making it choppy. The best I can say is the wind does ease slightly to a moderate breeze, but it’s not enough to save it.
Overall, Irmas/Leftpoint needs a clean spell with offshore wind to shine, and this forecast doesn’t deliver it. It’s a frustrating run of “poor surf conditions” across the board. Hang in there, but don’t plan your week around it.
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.
