The Lowdown
Alright, let’s see what’s cookin’ for the next couple weeks.
Honestly, it’s a long stretch of flat and small waves. We’re talkin’ a good week-plus of hardly anything worth paddling out for. The only real moment that’s got any punch is a ways off.
We’re looking at a whole lot of days with tiny, weak surf and winds that are all over the place. The first time we see anything with some size is the afternoon of Saturday, September 12th. That’s more than a week of nothing.
So, for that Saturday afternoon, Waikiki finally wakes up. The swell is going to be around 8 feet, coming from the southeast with a period of 8 seconds. That’s a solid size – it’s going to be too big for the beginners, and better suited for the guys who know what they’re doing. The wave energy is strong, clocking in at 851, so there’s plenty of power. The wind is a moderate cross-offshore, which should keep the surface pretty clean. The 8-second period means it’s more of a windswell, so the waves will be a bit steeper and more stacked up, not the clean, lined-up groundswell you’d get from a longer period. It’s a beach and reef setup, so with this size, the reef breaks might offer some better shape if you pick the right spot.
The water temperature is about 51°F, which is a touch warmer than normal for this time of year, so that’s a small win.
After that, it’s back to small stuff. The morning of Sunday the 13th has some waves around 4 feet from the east-southeast, but the wind is cross-shore, so it won’t be as clean. The rest of the days stay tiny and messy, with only an occasional knee-high wave and mostly onshore or cross-shore winds.
So, bottom line: if you can wait, that Saturday afternoon is your best bet. The rest of the 16 days is pretty much a dud. Don’t expect much.

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.
