The Lowdown

Alright, Rusty here. Let’s talk about what’s happening in the water. It’s a pretty bleak run for the next week and a half at Waikiki, so don’t be in a rush to paddle out.

We’re looking at a long stretch of little to no surf. From Saturday the 8th right through until the morning of Monday the 17th of August, it’s flat, weak, or just plain messy. Nothing worth getting wet for. The most you’ll see is a tiny 2ft on the 8th, but with a stiff 22 mph west wind, it’s a write-off. The water temp is about average for the time of year, nothing to write home about.

Things finally get a pulse on Monday the 17th of August, but it’s a rough one. The swell jumps up to 8ft from the east, with a short, punchy 8-second period and combined energy hitting 694. The wind is howling cross-shore at 19 mph, so expect lumpy, choppy, ugly conditions. Not for the faint-hearted, and honestly, it looks more like a kite session than a surf.

Tuesday the 18th gets even bigger and meaner. We’re seeing 10ft east-southeast swell, period up to 11 seconds, and the combined energy rockets to 2574. That’s a lot of juice. But the wind is a strong 25-28 mph, cross-onshore and messy. This is for experts only, and even then, it’s a battle.

Now, here’s the one true standout. The morning of Wednesday the 19th of August. The swell is still a solid 10ft from the southeast, with a long 12-second period and a massive 2107 combined energy. The wind swings clean offshore from the southwest at 28 mph. That’s a gale, but it’s offshore, so the waves will be holding up, shaped, and clean. The catch? It’s too big for this break. The comment says it’s hard to paddle into. So if you’re a seasoned charger and you know the channel, you might get a few bombs. But for the average surfer, this is a look-and-learn day. The afternoon sees the wind crank up to a near gale, making it nearly impossible.

After that, the swell drops but stays rideable. Thursday the 20th of August morning has 6ft from the east-southeast, 11-second period, and 734 energy. The wind is cross-off, so it’s clean. The score is low, and the comment says it’s marginal. The following days fade into smaller, wind-affected slop right through to the 23rd.

So, if you’re holding out for clean surf, the best bet is that Wednesday morning, August 19th, but only if you’re a local who knows the break and can handle big, powerful, offshore lines. Otherwise, this forecast is a long one to wait through.

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.
