The Lowdown
Alright, let’s take a look at the next 16 days for Waikiki.
Right off the bat, I’ll be straight with you—this forecast is a tough one. The whole first week is basically a write-off, with tiny, weak, poor-quality surf. The water is sitting at 51°, which is much warmer than usual for this time of year—that’s a real standout, but doesn’t help the waves one bit. From Monday, August 31st, right through to the end of the first week, we’re looking at knee-high dribble from the east at around 0.7 ft to 2 ft, with periods around 8 to 10 seconds. The combined swell energy is weak, mostly sitting between 23 and 73 (weak energy). Winds are often cross-on, onshore, or just messy. There’s a brief moment on Thursday afternoon, September 3rd, with a little offshore wind from the SSW at 15 mph and 2 ft east swell, but it’s still very ordinary. The only real glassy moment is Tuesday afternoon, September 1st, but with 1 ft on offer, it’s not worth paddling out for.
The week of September 7th to 13th stays pretty grim. Most days are still small, poorly directed, with weak energy. There’s a bit of a bump on Sunday, September 6th afternoon—6 ft from the ESE at 10 seconds, with 553 combined energy (moderate wave energy) and clean conditions—but that’s a marginal, questionable tide day. Still, it’s the first time you’ll see something with a bit of push. The rest of that week is a washout with onshore winds and tiny, short-period slop.
The standout of the whole 16 days comes on Tuesday, September 15th. The morning session shows 4 ft east swell, 11-second period, with clean conditions and a cross-off wind from the west at 15 mph. The combined energy is 363 (moderate swell energy). That’s the best we’ve got—clean, decent size for Waikiki, and manageable. The afternoon gets messy with a strong 25 mph offshore, making it hard to paddle into. That Tuesday morning is your best bet.
If you’re a beginner, the only time that’s really small enough and potentially clean is that Tuesday afternoon glassy session on September 1st, but honestly, the waves are just too small. For everyone else, wait for the 15th.
Signing off, 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.
