The Lowdown
Alright, this is your local surf reporter Rusty, with a look at the next 16 days for the Waikiki area.
We’ve got a bit of a mixed bag here, folks. The start of the period is looking pretty average, but there’s a little window of fun clean surf coming up that’s worth getting excited about if you’ve got flexible timing.
The main spot to keep an eye on is Waikiki. Let’s be real, the first few days are a bit of a write-off. Tuesday the 4th has a bit of swell, but it’s messy. On the morning of the 4th, there’s a 3 ft SE swell with a 10-second period, and the water is a very unusual 51°F – that’s much warmer than normal for this time of year. The wind is glassy out of the east at 3 mph, so it’s clean, but the wave comment says “expect good surf conditions.” The combined energy is moderate (227). It’s surfable, but nothing to write home about, and it drops off fast.
Wednesday the 5th and Thursday the 6th are a washout – onshore winds, rain, and the swell disappears. We’ve got a gap of about four days with no real recommendations until we get to the good stuff.
Now, here’s the standout. On Tuesday morning, August 11th, Waikiki is where it’s at. We’re looking at a 4 ft SE swell with a 10-second period, which is a nice, solid size for the break. The wind is offshore from the southwest at 9 mph, and the wave comment says “expect good surf conditions.” The combined energy is moderate (251). This is the cleanest, most promising window in the whole forecast. The offshore wind is a major positive, so the waves should be clean and well-shaped. It’s not huge, but for a beginner-friendly spot like this, it’s perfect. Keep in mind that crowds are possible here, so get out early.
After that, the wave energy drops right off. From Wednesday the 12th onwards, the swell is tiny, and the wind is all over the place. There’s a brief moment on Sunday the 16th with a light offshore wind, but the swell is only 2 ft, so it’s really just a bump. The rest of the second week is a long, flat run with very little energy. It’s looking like a bit of a dry spell.
So, the bottom line: hold out for that Tuesday morning the 11th at Waikiki. That’s your best bet. The rest of the time, you’re better off doing something else.
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.
