Alright, Rusty here again. Let’s break it down in feet and miles per hour for you. The news ain't any better.

For Irmas/Leftpoint over the next couple of weeks, we’re looking at a steady, ugly pattern. That east-northeast wind is just hammering the place, and the surf is always chopped up. There’s always some swell in the water, with wave energy running moderate to strong (values between 449 and 1040), but the quality is garbage.

Starting Tuesday morning, July 7th, we’ve got a solid 8ft of swell out of the east-northeast, but it’s a short 8 seconds apart and getting blasted by a 25 mph cross-shore wind. It’s all messy cross-chop and poor surf conditions. Wednesday and Thursday are the same story—7ft or so, short period, and fresh to strong cross-shore winds. Nothing clean.

Come the weekend of July 11th and 12th, it’s more of the same. Saturday morning hits 8ft again, but that cross-shore wind ruins it. Sunday afternoon is also 8ft, but again, the wind chops it up. The energy is there, but the waves are junk.

Into the second week, from July 13th onward, the pattern holds. Swell hangs between 5ft and 8ft, but that persistent east-northeast wind just won’t quit. Periods stay short, mostly 7 to 8 seconds, keeping everything lumpy. By July 22nd, the swell drops to 3ft from the east, but the period stretches to 14 seconds. That long period groundswell would be a treat, but with a 19 mph cross-shore wind from the northeast, it’ll still be blown out and messy.

Because the wind is so consistently cross or cross-on, and the swell is mostly short-period windswell, this setup looks way more interesting for kite surfing than for a paddle session. There’s no standout day here. The best you could hope for is a lull in the wind, but the forecast doesn’t give us one. It’s a blank run for the next 16 days. Keep your board in the car, but don’t hold your breath.

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.
