The Lowdown
Hey, Rusty here again. Let's break down the same outlook for you in feet and miles per hour.
Look, I'm not gonna sugarcoat it – the next couple of weeks are looking pretty flat and quiet for the Waikiki area. The first day we see anything that's even surfable is Thursday, September 3rd, but it's a real struggle to call it a proper session. After that, there's a big gap of several days with next to no real recommendations, so don't rush to wax your board.
Thursday, September 3rd is the only window that's worth a mention. Waikiki will be seeing a tiny 2ft easterly swell, with a period of 9 to 11 seconds. The combined energy is weak, only about 61 (110 in the afternoon) of what we'd call real wave energy. The water is sitting at a very unusual 51°F, which is a whopping 4°F warmer than normal for this time of year – feels like a warm bath, but the waves are tiny. The morning has a moderate offshore breeze, keeping things clean, but the 12 mph wind from the WSW is making it a bit of a struggle. The afternoon picks up a fresh 19 mph offshore wind, but it's a bit too strong for the size. You'll be scratching for a little 2ft wave, but it's not what you'd call a standout.
Honestly, if you're after a proper surf, this isn't the week. The swell is tiny, the energy is low, and the conditions are just average. If it were a bit bigger and the wind was glassy, we'd be talking, but for now, this is a quiet window. The only real positive is that for a beginner, the tiny, clean waves on Thursday morning could be a fun, safe paddle, but it's nothing to write home about.
After that, it's a long stretch of nothing but poor surf conditions right through to the end of the forecast. The energy levels drop to near zero, and the wind picks up from the north, making it lumpy and choppy. There's a few days with glassy conditions on the 12th, but no swell to speak of. It's a real bummer, but that's the way it goes sometimes.
Rusty, signing out.

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.
