Alright, let’s be straight with you. Right now and for the foreseeable future, this is a tough stretch for Waimanalo. There’s surf on the charts, sure, but the conditions are just not playing ball. The wind is parked onshore from the ENE almost the entire time, and that’s going to put a chop on everything. For a beginner spot like this, that’s a real bummer.
Looking at Sunday July 5th, we’ve got a swell coming in at 6 ft from the ENE with a short period of 8 seconds. The combined energy is moderate, sitting at 366, but with a fresh breeze at 22 mph straight onshore, the quality is shot. It’s the same story through the afternoon, and into Monday and Tuesday, with the swell bumping up to 7 ft to 8 ft and the wind getting even stronger – up to 25 mph. That’s a strong breeze, and the waves will be a mess. By Wednesday and Thursday, the swell drops back to 6 ft to 7 ft, but the wind doesn’t let up. The period stays short, mostly 7 seconds, so there’s no real push or shape.
The second week doesn’t offer much hope either. From July 12th onward, we’re still stuck with an onshore ENE wind and short-period swell. The combined energy dips into the 200s – weak to moderate – and the swell height hovers around 5 ft to 6 ft. On July 19th, we get a brief moment of cross-onshore wind, but it’s still moderate and choppy. Honestly, there’s not a single standout day in this whole 16-day window that I’d tell a surfer to paddle out for at Waimanalo.
It’s a rough run for the area, but the surf is fairly consistent in size, so it’s not a total flat spell. The onshore wind is just wrecking the potential here. With the swell over 8 ft on some days and the strong wind, this setup would honestly be more interesting for kite surfing than paddle surfing if you’re looking for a thrill. Keep hoping the wind shifts.

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.
