The Lowdown
Alright, let’s break this down for the next couple of weeks. Honestly, it’s a tough look. We’ve got a long stretch of nothing special before anything really shows up.
The whole pattern is locked in with side-off winds from the ENE, mostly fresh breezes, so the surface stays clean, but the swell quality is garbage for a long time. From Monday, August 24th, all the way through to Tuesday afternoon, September 1st, there’s a huge gap with no real surf worth talking about. Days of poor, marginal conditions with short-period windswell that’s just weak and disorganized. That ENE swell runs from about 2 feet to nearly 7 feet, but with a period of only 7 to 8 seconds, it’s gutless. The combined swell energy is in the moderate range, but it’s all noise and no wave.
The first real chance of a good session comes on Monday afternoon, September 7th. That’s a long way out, so be cautious, but it’s the best looking day in the whole window. The wind is supposed to go glassy, with a light SE breeze at only 3 mph. That’s huge. We’ll see chest-to-head-high waves around 5 feet from the ENE with an 8-second period. The combined swell energy is moderate at 531. For a moment, conditions look really good, so if you can wait, that’s the day to mark.
The next morning, Tuesday, September 8th, also has some potential, but it’s more complicated. The swell jumps to around 8 feet from the ENE, with an 8-second period and a strong energy reading (1543). But the wind turns onshore from the South at 6 mph, which will chop it up. That size at Kewalos is getting serious, only for the experts. The afternoon cleans up a bit with a lighter SSE breeze, but the size drops back to around 7 feet.
It’s a long wait through a lot of flat and mediocre days. The standout is that glassy Monday afternoon on September 7th. Hang in there.

Information about the Kewalos Surf forecast
The above surf forecast table for Kewalos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kewalos can be found by selecting the local surf guide option on the grey menu. Our Kewalos 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 (Kewalos) 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 Kewalos 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.
Kewalos 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.
