The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the next 16 days at Makapu'u are looking pretty grim. We’re staring down the barrel of a long stretch of onshore wind and messy surf. The wind is locked in from the ENE for most of the period, which is straight onshore here, and that’s gonna keep things choppy and blown out.
Let’s start with the first few days. Saturday the 25th and Sunday the 26th are a write-off. The ENE wind is howling at 22-25 mph, and while there’s some swell on the charts, the combined energy is moderate (around 1200-1400), but the wind is ruinin’ it. The water temp is about average for the time of year, nothing weird there.
Monday the 27th and Tuesday the 28th are no better. The wind stays onshore, and on Tuesday we see a bigger swell push in, with combined energy jumping to 2223 and then 3494, but it’s a wind-affected, lumpy mess. The swell from the E at 13 seconds is a decent groundswell, but with that onshore wind, it’s just not gonna be clean.
We get a tiny window on Wednesday the 29th. The wind swings to a lighter S-SSE breeze, going cross-off in the afternoon. The swell drops off a bit, but you’re looking at 6.9 ft from the ENE at a short 9 seconds. The combined energy is moderate (994). The surf is marginal, but it’s the only time in the first week and a half where the wind is not howling onshore. It’s not a standout, just a “maybe if you’re desperate” kind of day.
Then it’s back to the ENE wind machine from Thursday the 30th right through to August 9th. The wind is fresh to strong, straight onshore. The swell size bounces around, with some bigger days like August 1st seeing 9.8 ft, but the period is short (8 seconds) and the wind is cranking. The combined energy stays moderate to strong, but it’s all for naught. This setup is honestly more interesting for kite surfing than for paddle surfing. The conditions are consistently "poor".
There are no standouts in this entire 16-day window. The only break in the region is Makapu'u, and it’s not gonna fire. Keep the board in the car, check the forecast in a few days, and hope the wind pattern shifts. We’ll be waiting.

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