The Lowdown
G’day, I’m Rusty. Let’s take a look at what’s cooking over the next couple of weeks, in feet and miles per hour.
Right from the start, it’s a tough run. Makapu’u is the only break in the mix – a reef setup that’s exposed to swell – but for the first stretch, there’s nothing but poor surf. The water’s sitting at 81°, which is about normal for this time of year. Problem is, the trades have been howling from the east-northeast at 19 mph, straight onshore, and the wave quality is rubbish. There’s a big gap from Sunday the 6th right through to at least Monday the 14th with no real clean windows. The swell energy is often moderate to strong, but those winds kill it.
The first half-decent moment comes on Tuesday the 8th. Makapu’u on Tuesday morning gets a south cross-offshore breeze at 19 mph, with 6 ft swell from the east-northeast, period around 11 seconds. The combined energy is high (1860), but surf is still marginal. The afternoon is a tad better: wind drops to 12 mph, swell sits at 6 ft from the east-northeast with a 10-second period, and energy moderates (1055). Conditions are clean, so this is your best bet in the first week. It’s not a standout, but if you’re itching, Tuesday afternoon is the pick. Keep in mind, Makapu’u can get crowded sometimes, and it’s an advanced reef break.
The rest of the first week and into the second week is grim. Wednesday the 9th offers some small south-southwest groundswell at 3 ft with a long 14-second period, but the energy is weak (583) and light cross-onshore winds from the east-southeast ruin it. After that, it’s nonstop onshore trades and building swell that’s too big for beginners (over 8 ft some days) but still blown out. By Thursday the 17th, there’s 8 ft from the east with a short 8-second period and strong energy (1227), but the wind is still onshore from the northeast at 19 mph. That’s just lumpy whitewater – better for kites than paddles.
Looking further out, on Wednesday the 16th, there’s a spike from the south-southwest with a very long 18-second period and 3 ft swell, but fresh onshore wind ruins it. The pattern holds to the end of the 16 days. On Sunday the 20th, we see 8 ft from the east-northeast, but the period is a short 7 seconds and the wind is cranking at 22 mph onshore. That’s expert-only, and even then, it’s a struggle.
So, plain and simple: this 16-day window is a downer. There’s no true standout day. If you want the best of a bad lot, Tuesday the 8th afternoon offers the most rideable conditions, but it’s marginal. The energy is often strong, but the wind won’t cooperate. For a spot that’s usually fairly consistent, this is a rough patch – but forecasts shift, and it won’t stay this way forever. Hang in there.

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.
