The Lowdown
Right then, let’s talk about what’s on offer for the next little while. Honestly, it’s a pretty flat stretch for the most part, so we’re looking at a long wait for anything decent. There’s a big gap of nothing much happening for the first week or so, with only a tiny window of something rideable towards the end of the first week before it all goes quiet again.
The first chance to get wet is on Thursday, the 27th of August. Waikiki should see a small, clean pulse in the afternoon. The swell is coming from the southeast at 3 ft, with a period of 12 seconds, which is a proper groundswell. The energy is moderate, sitting at 270 (combined swell energy). The wind swings offshore from the southwest with a light breeze, so the waves should be clean and lined up. This is your best bet for the whole outlook, but it’s a small one, better suited to a longboard or a funboard. The water is a touch warmer than normal for this time of year, sitting at 50°F.
After that brief window, it’s back to the doldrums. From Friday the 28th of August right through to the 9th of September, the surf is poor to non-existent. You’ll see tiny, weak swell from the east, mostly under 2 ft, with short periods and onshore or cross-shore winds. The energy is consistently low, often in the double digits (44 to 109). It’s a frustrating run of small, chopped-out conditions. There’s a little bump in energy on the 9th of September – 109 at 3 ft from the east – but it’s a messy, cross-onshore wind from the north-northeast and the period is only 8 seconds. It’s not worth getting excited about.
So, the honest truth is: if you’re desperate, you’ve got Thursday afternoon. Otherwise, it’s a waiting game. The setup is so small and weak for so long that it might actually look more interesting for a kite surfer than a paddle surfer on those gusty days.

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.
