IMPERIAL VERSION

Alright, let’s break it down in feet and knots. Rusty here, and I’ll be honest, this Waimanalo forecast is a tough pill to swallow. There’s a long stretch of days with the same old story: a solid onshore breeze from the ENE, and a swell that’s got the height but not the quality.

The wave heights will be running 5 to 7 feet, and the combined energy gets up into the moderate range (around 450), but with the wind blowing 15 to 22 knots onshore and a short period (mostly 7-8 seconds), it’s going to be bumpy, choppy, and generally poor. The swell direction is ENE to NE, which is not the optimum for this exposed beach.

Starting Thursday, 3rd July, the water temp is about 79°F, which is average for this time of year. No surprise there. But the conditions are the same day after day. The first week is a write-off – onshore winds, poor surf quality. The combined swell energy is moderate, but it’s all wind-slop, not real groundswell. It’s just not gonna be a fun paddle.

There’s a drop in size around the 13th and 14th of July, with waves falling to 3 feet and the energy dipping to 181. Still messy. The swell starts to pick up again on the 18th, back to around 5-6 feet and energy of 252, but the wind is still cross-onshore or onshore. For a beach break like this, that onshore flow is a killer. This setup honestly looks more interesting for a kite-surfer than a paddler.

I can’t point to a single standout session in this whole 16-day window. There’s no clean, glassy morning in sight. The spot is fairly consistent for swell, but the conditions are just not cooperating. If you’re absolutely jonesing, you might find a groveler wave on the high tide, but don’t get your hopes up. This is a dry spell for real surf.

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.
