Hey, Rusty again. Let's break down the same outlook but in feet, miles per hour, and Fahrenheit, 'cause that's how some of us read the ocean.

Straight up – there's zero worth paddling out for at Waimanalo over the whole 16 days. From Sunday July 5th through Monday July 20th, every session is rated poor. No exceptions.

This break's usually fairly consistent, especially for beginners, and it likes a NE swell. But we're stuck with a persistent ENE swell – off the ideal angle – and a constant onshore breeze that's gonna wreck any chance of clean surf. Wind speeds are 15 to 25 mph, mostly onshore or cross-onshore, making for choppy, lumpy conditions. Swell period is short, 7 to 8 seconds, so it's just wind slop with no power. Wave heights run 6 to 8 feet, but with that wind and period, it's all closeout junk.

Combined wave energy sits between 241 and 592 – moderate numbers on the scale, but again, no quality. Water temp is 80°, right about average for this time of year with a tiny anomaly of +0.5°F, so nothing unusual there.

If you're a beginner hoping for mellow waves, don't bother. If you're advanced, there's nothing to get excited about either. This stretch looks better for kite surfers – that steady onshore wind and lumpy surface will keep them smiling while we sit on the beach.

Sometimes the surf just goes flat and windy. Don't force it. Forecasts can change, but right now, this is a solid "stay home" call.

– 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.
