The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for Waikiki over the next couple of weeks. I gotta be straight with you—this isn't the kind of forecast that gets the blood pumping. We're looking at a long stretch of small, marginal surf, and the wind is a persistent problem.
For the first week or so, from Saturday the 29th of August right through until the start of September, the trade winds are pumping hard out of the ENE at 18 to 25 mph. The waves are tiny, barely pushing 2 ft. Even though that wind is offshore and clean looking, it's so strong it's making it a real battle just to paddle out and get into these little runners. The water temp is sitting at a nice 81°, right about average for this time of year, so no surprises there. The combined swell energy is weak, struggling to hit even 300 (274). It's just tough going.
We do see a slight bump in energy come Tuesday the 1st and Wednesday the 2nd of September, with the combined energy climbing into the moderate range (485). The swell straightens up from the S and SSW, with a long period of 16 to 18 seconds, which is decent groundswell. But it's still only 2 to 3 ft. The wind stays a fresh offshore breeze, so while the surface will be silky, it's just not got the size to get excited about. This pattern of "marginal" and "poor" labels carries on and on.
The first real standout, and it's really the only one worth marking on the calendar, comes on Wednesday the 9th of September. For the morning we've got moderate offshore wind from the ENE at 15 mph, with a clean 2 to 3 ft SSW swell (13 second period). The combined energy is moderate at 411. It's the afternoon session that really snags my attention though. The wind drops a notch to 15 mph, still offshore, and the forecast is calling for "good surf conditions." It's not big, but it could be the most fun wave of the whole outlook.
Then, on Friday the 11th and Saturday the 12th of September, we get a couple of solid windows. Friday afternoon sees a clean 2 to 3 ft SSW groundswell with a moderate 15-second period, light offshore NE wind at 15 mph, and combined energy of 355. The next morning, Saturday the 12th, is the pick of the weekend: clear skies, a moderate offshore breeze from the ENE at just 12 mph, a similar 2 to 3 ft SSW swell (15 seconds), and combined energy of 311. That's the formula for clean, fun, learner-friendly waves at Waikiki. You'll be sharing the peak for sure—this spot is *often* crowded—but with conditions that clean, the trade-off is worth it.
So, the bottom line? This is a long, drawn-out period of small conditions. There's no big swell on the horizon. The standout sessions are limited to September 9th afternoon, September 11th afternoon, and especially September 12th morning. If you have a longboard and some patience, there's a little window of goodness.
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.
Waikiki is 5 km (3 miles) from Honolulu. If you plan a vacation in Oahu, look for hotels and other accommodation in Honolulu. Honolulu has rooms for a wide range of budgets as well as car hire and transport links.
