The Lowdown
Alright folks, Rusty here. Let's have a look at what's on offer for the Waikiki stretch over the next couple of weeks.
Gotta be straight with you from the jump – this outlook is a tough one. We’ve got a long, lean stretch ahead. The first week is basically a write-off, and the second week only offers faint glimmers that are more for the die-hard than anyone looking for a proper session.
For the first several days, right through to the end of July, it’s a flat spell. The combined energy is weak, barely cracking 100 (coming in around 94 or less), and the swell heights are tiny, mostly under 3 ft. The best you’ll see is a bit of waist-high slop on the morning of Friday the 17th, with a weak 3 ft from the ENE at 8 seconds, but it’s crossed up with a rain shower and a light cross-onshore breeze. The wind goes offshore for the afternoon, cleaning it up, but the wave quality is still described as "very ordinary." After that, for the next week and a half, the story is the same: small, weak, and mostly poor conditions. The wind is often a cross-off or side-shore breeze, which keeps the surface clean, but there’s just no push in the water. This is a blank run that lasts nearly two weeks before anything interesting shows up.
Then, we finally get a flicker of life on the very last day of the outlook, Saturday the 1st of August. A new swell tries to push in, with a combined energy reading of 111 in the morning, climbing to 130 by the afternoon. That’s still only moderate energy, but it’s a big step up from the dust we’ve been seeing. The swell is small, only 2 ft to 2 ft, but it’s coming from the ESE with a very long period of 13 to 14 seconds. That long period is a true groundswell, meaning the waves that do show will have a lot more shape and push to them, but with such a small height, it’s going to be a very inconsistent, long-period bump. The wind is a screaming 25 mph from the southwest, which is strong offshore for Waikiki. It’ll be glassy clean, but that’s gale-force stuff. It’s going to be a real battle to get out there, and paddling into those little 2 ft waves will be a workout. This is deep expert territory, and honestly, the setup looks far more interesting for kite surfing than paddle surfing.
So, to sum it up: take the next two weeks off. The water temperature is a touch warmer than normal at 50°, but that’s the only thing going for it. The only potential standout is that Saturday the 1st of August, and even that is a "promising but risky" bet for the most dedicated experts at Waikiki. Patience is the call.
Rusty.

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