The Lowdown
Alright, let's talk about the next couple of weeks. I gotta be honest with you, it's a rough stretch for anyone looking to paddle out on the east side. For the entire 16-day window, every single session at Makapu'u is getting a "poor surf conditions" tag. The wind is just relentless, blowing onshore from the NE and ENE, and at times it's a strong breeze at 25 to 28 mph. That's gonna chop everything to pieces. There are no standout days, no hidden gems. It's a blank run, plain and simple. For a spot that's fairly consistent, that's a real kick in the teeth.
The first few days, from Friday the 7th of August well into the next week, we're looking at messy, weak surf. The swell is a mix of short-period windswell with periods around 6 to 8 seconds, which won't have any shape to it. The combined energy is moderate, but with that onshore breeze, it's all just white water.
Then, around the 12th and 13th of August, there's a shift. A longer-period groundswell rolls in from the south with periods of 15 to 18 seconds. The energy jumps up to strong values. But, and it's a big but, the wind is still howling onshore from the ENE. For a break like Makapu'u that's exposed to the swell, that long-period energy is gonna be mushing into a stiff headwind. It's a setup that looks way more interesting for kite surfing than paddle surfing right now.
From the 14th of August onwards, it just gets worse. The breeze picks up again to a strong breeze, and the swell from the ENE tops out at over 8 ft by Sunday the 16th. That's big, but with the wind, it's just a washing machine. That size is only for experts anyway, but it won't be any fun for them either. There's a brief window on the 19th and 20th of August where the wind eases back, but it's still onshore, and the swell is small and weak. The last few days of the outlook, the wind goes cross-on, which is just as bad.
Water temp is about 80° down the beach, which is about average, so you won't freeze waiting for a clean wave that never comes.
Honestly, if you're desperate for a paddle, wait for one of those brief moments when the wind drops, but don't hold your breath. The forecasts can change, but as it stands, the only thing breaking is your heart.

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.
