The Lowdown
Alright, this is Rusty, and I’m looking at the surf picture for the next couple of weeks. Real talk: it’s gonna be a tough stretch for anyone looking to get a decent wave. This is one of those periods where you might wanna leave the boards in the truck and just watch the ocean.
The outlook starts now, and for the first several days, honestly, it’s a write-off. We’ve got a solid, consistent swell running at Makapu'u (reef), but it’s being hammered by strong onshore winds. The wind is blowing straight from the ENE at 18 to 28 mph, and that’s just ruining any chance of a clean face. The swell is there, with heights around 4 ft to 10 ft, and the combined wave energy is strong, hitting values like 1403, but the wind is just tearing it to shreds. You’re looking at “poor surf conditions” across the board for the first week. The water temperature is about average for late July, nothing to write home about.
There’s a slight flicker of hope around Wednesday the 29th of July. The wind drops right down to a light breeze, almost calm in the afternoon at 3 mph. The swell is still big, around 8 ft to 10 ft, coming from the ENE and NE. The wave comment shifts from “poor” to “marginal.” The energy is still high (2321 and 1475), but the short period of 10 to 11 seconds isn't ideal for a reef break. It might be doable for advanced surfers, but the quality is a big question mark. It’s not a standout, just a maybe.
After that, from the 30th of July right through to the 10th of August, it’s a long, bleak run. The wind picks back up, and we’re back to “poor surf conditions” day after day. The swell is there, sometimes chest to head high, but the wind is relentless. The period is short, often 8 seconds or less, which means weak, choppy waves. The combined energy stays moderate (between 310 and 1186), but it’s all junk. The only break in the clouds is a very late call on the 9th of August, where the wind drops a little, but it’s still onshore and the forecast is marginal at best. There’s a risk of thunderstorms on the 7th, 9th, and 10th of August too, which isn’t helping.
So, what’s the best on offer? Honestly, there isn’t a true standout. If you’re desperate and an expert, the Wednesday the 29th of July session might be the only window. The swell is big (8 ft to 10 ft) and the wind is light, but the short period and cross-onshore direction mean it’s gonna be a messy, lumpy paddle. For the rest of us, it’s a waiting game. The forecast can change, but this is a long stretch of nothing special.
This is Rusty, signing off.

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.
