G’day, Rusty here. Look, I’m not gonna sugarcoat it – the next 16 days are a tough watch for anyone looking to get a decent wave. There’s a lot of wind and chop making a mess of things, so you’ll need to be patient.
Kicking off Monday, July 6th, we’ve got swell running at 7ft with a short, weak 7-second period from the ENE, but the wind is a strong cross-shore at 25 mph. The combined wave energy is moderate (937). This is messy cross-chop right from the start, and it sets the tone. The only break on the cards is Irmas/Leftpoint, a reef setup. Water temp is sitting at 80°, right on the money for this time of year – no surprises there. But honestly, the conditions are poor. That strong cross-shore wind sticks around like a bad cold, with periods of fresh breeze, but the swell height hangs between 5ft and 8ft through to July 11th. The period barely gets over 8 seconds, so the waves are lumpy and gutless. The combined energy dips and climbs (from 476 up to 985), but it never translates into anything rideable because the wind just won’t let up.
Into the second week, around July 14th, the swell drops to around 5ft and the wind eases back to 22 mph, but it’s still cross-shore. The energy level drops to a low of 263, which is weak. It stays a bit of a slog. By July 16th, the swell direction swings to a 2ft SSW groundswell with a very long 17-second period. That’s a bit of a tease because it’s long-period energy that would normally be great for a point or reef, but the cross-shore wind (still 22 mph) will kill the shape. The reef at Irmas should help hold it together, but it’s a tough call for anything clean.
Look, the best window – and I’m stretching it here – is from July 18th. The swell drops a bit to 5ft from the E, and the wind backs off to a moderate 16 mph cross-shore. The period stretches to 7 seconds, still short. The combined energy is weak (388). It’s the most manageable it’s been, but “manageable” isn’t the same as “good.” For the entire 16-day run, nothing stands out as a true standout. The persistent cross-shore wind and short-period chop ruin every session. If the wind ever goes offshore or glassy, this reef would fire with the size on offer, but it’s just not happening.
If you’re desperate, and the wind suddenly shifts, Irmas/Leftpoint is your only shot. Otherwise, this stretch is one to sit out.
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.
