The Lowdown
Alright, let’s have a look at Nimitz Beach. It’s a reef break, pretty beginner-friendly, but it’s inconsistent and can get a few people out there. The water temp feels about average for this time of year.
Honestly, the outlook for the next 16 days is quiet. There are a few windows where it might be worth a paddle, but nothing is firing. The swell stays small, mostly under 3 feet.
We start off on Thursday the 10th with a bit of a messy morning – cross-shore wind and just 2ft of swell from the SSW. That long period of 16 seconds is nice, but the energy is weak (354) and conditions are poor. A better bet is the afternoon: the sun’s out, the wind turns a solid offshore, and the wave energy jumps up to a moderate 513. Still only 2ft, but it’s clean and rideable.
Friday the 11th is the standout of this whole run. Morning stays clean with 2ft from the SW, period 16 seconds, and light offshore breeze. The energy is moderate (324). The afternoon gets even better: light breeze, clean lines, 2ft and shorter period at 15 seconds, but the energy is still good (275) and the conditions are described as good. This is your best bet – small but clean.
Saturday the 12th holds similar size but the morning gets a light cross-shore breeze that puts a small crinkle on the surface. Afternoon improves with light offshore wind and just 2ft, but the period stays long at 16 seconds. Not great, but sessionable.
Sunday the 13th drops off. Morning has 2ft from the SW, but the wave energy is low (163). By the afternoon, it’s down to 1ft and only 140 energy – barely worth suiting up.
Monday the 14th stays small, but the afternoon has a real interesting spike: 2ft from the SW but with a very long period of 22 seconds. That’s proper groundswell. Energy jumps to 276, but at this size, it’s just a novelty. It’ll be clean with offshore wind though.
Tuesday the 15th sees a slight bump to 3ft from the SW, period 20 seconds, giving strong energy (622). But the wind is cross-onshore, light, which puts a bit of a wrinkle on it. It’s marginal.
The rest of the run into the second week is mostly small, with wind issues or poor conditions. A few days have moderate to strong energy, like the 16th (795) and the 18th Friday (1016), but the swell is only 3ft to 4ft and the wind stays fresh. Cross-offshore breeze keeps it clean, but the scoring is low – just not great quality waves.
By Tuesday the 22nd, we get a weird shift: swell from the east at only 4ft but a short, weak period of 8 seconds. That’s windswell, sloppy. On the 23rd, things tidy up a little with 2ft from the SSW at 18 seconds, clean and light breeze. It’s a small but clean option for a longboard or a foiler.
Overall, Friday the 11th afternoon is the pick – small, clean, and offshore. The Monday the 14th afternoon with that 22-second period is a curiosity if you love tiny, perfect lines. Everything else is small and ordinary. No big swell coming, just mellow waves for the patient.

Information about the Nimitz Beach Surf forecast
The above surf forecast table for Nimitz Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nimitz Beach can be found by selecting the local surf guide option on the grey menu. Our Nimitz Beach 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 (Nimitz Beach) 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 Nimitz Beach 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.
Nimitz Beach is 5 km (3 miles) from Makakilo City. If you plan a vacation in Oahu, look for hotels and other accommodation in Makakilo City. Makakilo City has rooms for a wide range of budgets as well as car hire and transport links.
