The Lowdown
Alright folks, Rusty here with a look at the surf ahead for Waikiki. The water is sitting at 81°, which is pretty much spot on for this time of year, so you won't need a thick suit.
The next sixteen days are a bit of a mixed bag. We've got a long stretch of small, weak energy, and it's not until the very end of the first week of September that we finally see a decent spike in size and quality. You'll have to be patient.
Let's start with this Wednesday, August 26th. The morning is a bit messy with a cross-offshore wind and a weak swell of 2ft from the SSW. The combined energy is only moderate at 578. The afternoon cleans up nicely though, with a clean offshore breeze and a 2ft S swell, but it's still pretty small. The energy is a touch stronger at 634.
Thursday, August 27th, is similar. The morning has some clouds and a fresh offshore wind, with a slightly better 4ft swell from the S, though the energy is still moderate at 723. The afternoon goes back to a smaller 3ft S swell.
Friday and Saturday, August 28th and 29th, are a bit of a write-off. The swell drops further, and the wind is strong, making it tough to get into waves. Sunday the 30th through to Tuesday, September 1st, we're stuck in a pattern of tiny 2ft to 2ft SSW swells. The wind is mostly offshore, keeping it clean, but the energy is weak, sitting between 195 and 377. It's not doing much.
Now, we finally get a glimmer of hope. On Wednesday, September 2nd, the afternoon looks promising. The wind goes offshore and moderate, and we see a 3ft S swell with a longer period of 16 seconds and moderate energy of 426. That's a sign of better groundswell.
The real standout comes on Saturday, September 5th. The afternoon is looking like the best of the lot. The wind is offshore and moderate, and the swell bumps up to 4ft from the E with a shorter period of 10 seconds. The energy is a solid 537. We're expecting very good surf conditions. This is the one to pencil in if you can only get out once.
After that, Sunday the 6th through to the end of the forecast, we're back to small, marginal SSW swells with the wind freshening up again. The energy stays weak, and the conditions are ordinary.
So, to sum it up, keep an eye on the afternoon of Saturday, September 5th. That's your best chance for some decent, clean waves here at Waikiki.
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.
Waikiki is 5 km (3 miles) from Honolulu. If you plan a vacation in Oahu, look for hotels and other accommodation in Honolulu. Honolulu has rooms for a wide range of budgets as well as car hire and transport links.
