The Lowdown

Alright, Rusty here, let’s talk about what’s on offer for the next stretch.

Right off the bat, I gotta be straight with you – the outlook for Waimanalo is a grim one for the next 16 days. We’re looking at a long, frustrating run of poor surf conditions. The wind is almost constantly hammering the coast from the ENE, putting it right onshore, and the sea state is just messy. There’s no standout session to get excited about, and for a spot that’s usually fairly consistent, this is a tough patch.

We start on Friday, 24 July, with a 7ft ENE swell, but it’s paired with a stiff 22 mph onshore wind. The wave energy is moderate (394), but the conditions are just poor. That same story repeats through Saturday and Sunday (25th and 26th July) – the wind stays strong and onshore, with swell heights hovering around 6ft to 7ft, and energy climbing into the strong range (up to 800). Still, the wind destroys any chance of a clean wave.

Monday the 27th and Tuesday the 28th see the swell energy really ramp up – we’re talking 927, 979, and then a massive jump to 1607 and 2212 on Tuesday. The swell size gets up to 8ft on Tuesday afternoon, but it’s all coming from the E with a moderate period of 13 seconds, and the wind is still onshore from the NNE. This is a lot of power (strong to very strong energy), but it’s unsurfable for a paddle board. If you’ve got a kite, maybe this setup starts to look interesting, but for a surfer? Forget it.

Wednesday, 29 July, is the closest we get to a glimmer. The morning sees a 10ft ENE swell with a cross-on wind from the N at 9 mph. The wave energy is still very strong (1733), but the report says it’s too big for this break. That’s a 10ft swell – that’s expert territory, and even then, the wind is cross-on, not clean. The afternoon drops to 6ft, with a light breeze, but it’s still only marginal.

From Thursday, 30 July, right through to Saturday, 8 August, it’s a wasteland. The wind stays onshore or cross-onshore, the swell direction is locked in from the ENE, and the period is short to moderate (7 to 15 seconds). The energy fluctuates from moderate to strong, but every single entry is marked as “poor surf conditions.” The water temp is sitting at 80°F, which is dead average for this time of year, so you can’t even blame the cold.

There are no good surf options in this 16-day window. It’s a blank run for Waimanalo. The wind just won’t let up, and the swell direction is all wrong for this break. That said, this spot is fairly consistent, so it tends not to stay poor for this long – forecasts can change. Keep an eye on it, but for now, I’d save the wax and wait for a better window.

Rusty.

Information about the Waimanalo Surf forecast

The above surf forecast table for Waimanalo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Waimanalo can be found by selecting the local surf guide option on the grey menu. Our Waimanalo 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 (Waimanalo) 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 Waimanalo 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.

Waimanalo is 7 km (4 miles) from 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.
