Table - best surf conditions forecast for Makapu'u over the next 16 days.
Alright folks, Rusty here. Let's be straight with you about Makapu'u. This is a reef break that needs a very specific window to fire, and looking at the entire 16-day outlook, I gotta say it's a tough stretch.
The big problem is the wind. We've got a relentless onshore breeze from the ENE just about every single day, and it's blowing strong—often 18 to 25 mph. That's a strong breeze to a fresh breeze, and it's going to trash the surface of the waves. On top of that, the swell is coming from the same ENE direction, which is completely wrong for this spot. This break is exposed to swell, but it needs it from the ESE to really work, and the wind is just making a mess of what little size we get. The water temp is sitting at 79°, which is right about average for this time of year, so nothing unusual there.
Friday 10th July – Thursday 16th July
The first week is a total write-off. We're looking at swell heights around 6 to 8 ft, but the wind is hammering it. The combined wave energy is moderate, but with that onshore blow and short period swell around 7 to 8 seconds, it's just messy and unrideable. The model is calling it "poor surf conditions" across the board, and honestly, this will be more of a blown-out washing machine than anything you'd want to paddle out into. If you're kiting, this might look interesting, but for a surfboard, it's a skip.
Friday 17th July – Thursday 24th July
The pattern doesn't change. More of the same. The wind stays locked in from the ENE at 18-25 mph. Swell stays in the 5 to 7 ft range with short period. There's a brief moment on the 15th and 16th where a long-period groundswell from the SSW shows up at 18 seconds, but it's only 2 ft and the wind is still onshore, so it's a tease. No good.
Friday 25th July – Saturday 26th July
The very end of the forecast doesn't offer any relief. Still onshore ENE wind, still short-period swell. The cycle continues.
The Bottom Line
There is no standout. There is no best session. The combination of constant onshore wind and the wrong swell direction means Makapu'u is a no-go for the entire 16-day window. Don't bother paddling out. Keep your board in the car and wait for a change in the weather pattern.
Rusty.

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.
