The Lowdown
Alright folks, Rusty here. Let's be straight with you. I’m looking right now at Waikiki over the next sixteen days, and the honest truth is, if you're wanting any real surf to ride, you’ll be waiting a good, long while.
The first solid chance of anything ridable doesn’t show up until Friday the 12th of September. And even then, it’s barely a whisper. The swell stays tiny – under 3 ft – all through the period, with very weak wave energy values sitting mostly in the low double digits or lower. There's just no umph behind it. For the first few days, the waves are basically non-existent, with poor surf conditions across the board. You get a little window later on with some offshore breezes and glassy conditions, but the swell height just doesn't cooperate.
Let's walk through it. Thursday September 10th and Friday the 11th are flat with glassy conditions but nothing to ride. Saturday the 12th shows a tiny increase, but it’s still under 3 ft, with a short period making for messy, weak waves. Sunday the 13th and Monday the 14th are the same story: small, weak and crummy. This “almost there but not quite” pattern holds through Tuesday the 15th and Wednesday the 16th – clean conditions some afternoons, but only 0.7 ft to 1 ft of swell. It’s heartbreaking, really.
The most interesting day for the entire run is probably Thursday the 17th of September in the afternoon with a Westerly cross-offshore wind and the swell bumping up just a touch to 3 ft from the NE. Still not a classic, but the combined energy hits 44 (still weak) and it’ll be clean. That’s about as good as this window gets. After that, the pattern continues with tiny surf and strong offshore winds towards the 21st and 22nd that will make paddling out a chore for very little reward.
Waikiki is a beach and reef setup that is fairly consistent, so this flat run is a bit of a rough patch. Because of the very small swell and strong winds at times, the setup looks far more interesting for kite surfing than paddle surfing for most of these days. When the swell does show a pulse, like on the 20th with offshore winds, it’s still only 3 ft of short-period slop.
Honestly, keep your board in the car and your expectations low. Check back with me in a fortnight.
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.
