The Lowdown
Alright folks, Rusty here. Let's be straight with you – this is a tough one for the usual spots. The whole 16-day window is looking pretty grim, with no real standouts to get excited about right now.
We're looking at a long stretch of poor conditions. The wind is hammering onshore from the ENE almost the entire time, which is going to chop up anything that tries to roll in. It's a solid block of days where you're better off doing something else.
The first real flicker of hope doesn't come until Tuesday the 28th of July, and even then it's a marginal call. We're talking about Makapu'u, a reef break that's fairly consistent. The water temp is about average for this time of year, so no surprises there. The morning of the 28th, we've got a moderate cross-onshore wind, swell from the ENE at 7.5 ft, with a period of 14 seconds. That's a long-period groundswell, which will give it some real push, but it's also a lot of water. The combined wave energy is strong (2464). The cross-onshore wind is going to leave it lumpy, though. By the afternoon, that wind picks up and the swell gets a bit bigger and more unruly. This is a break for the advanced crew given the size and the onshore chaos.
The next chance is on Thursday the 30th of July. The morning shows a gentle cross-onshore breeze with a 5 ft swell from the NE. The period drops to 10 seconds, which is a bit more manageable. The combined energy is moderate (619). It's still a marginal surf forecast, but with the lighter wind, the morning might offer a few cleaner, more workable waves at Makapu'u. The afternoon looks to drop off again.
Honestly, my friends, for the first two weeks of August, the outlook doesn't improve. The wind stays on it, the swell is messy, and the energy is all over the place. It's the kind of setup that looks more interesting for a kite surfer than a paddle surfer, given the constant strong wind and the beach break nature of the area. Don't hold your breath for a miracle; this is a blank run that's pretty normal for the area when the trade winds set in. Stay tuned, forecasts can change, but for now, keep the board in the car.

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.
Makapu'u is 13 km (8 miles) from the city of Kailua. If you plan a vacation in Oahu, look for hotels and other accommodation in Kailua. Kailua has rooms for a wide range of budgets as well as car hire and transport links.
