The Lowdown
Alright, let’s be real. Nimitz Beach is a reef break, good for beginners, but it’s inconsistent. Over the next 16 days, there’s no real standout session. The first few days are flat or nearly flat, with tiny 2ft to 2ft swells and light cross-shore breezes. The water temp is 81°, which is about normal for this time of year.
Tuesday morning August 4th has some clouds and a light ESE wind, but the swell is a weak 2ft from the SSW, period 12 seconds. It’s just poor surf. The afternoon gets a little better – a 1ft SSW swell with a very long 16 second period, and a clean cross-off wind. But the combined energy is only 181 (moderate), and the waves are “surfable but very ordinary.”
Wednesday and Thursday are similar: tiny swell, all around 1ft, with cross-off winds that keep the surface clean. But the energy is low, and it never gets above “ordinary.”
Come Friday the 7th, the swell bumps up a bit to 2ft, and the period stretches to 18 seconds on Saturday morning, with a combined energy of 615 (moderate). That’s the best of a bad bunch. But the wind is a fresh 22 mph cross-off, and the wave comment says “marginal.” Not worth it.
The second week gets a little more interesting. On the 12th and 13th, we see a 4ft to 5ft S swell, with a period around 16-18 seconds. The combined energy hits 1111 and 1138 (strong). But the winds are still a solid 22 mph cross-off, and the waves are called “marginal.” Not clean enough.
By the 16th and 17th of August, the swell size jumps up – 8ft to 10ft from the E, with a short 8-9 second period. That’s a lot of water, combined energy over 2300 (very strong). But the wind is cross or cross-off, and the short period means it’ll be a messy, close-out mess at this reef. This is expert-only, and honestly, it looks more like a kite-surfing setup than a paddle-surfing one.
The final few days drop back to tiny 2ft-2ft swells with very long periods (21 seconds) on the 19th, but the energy is moderate and conditions are still just “marginal.”
Bottom line: no real green light here. The reef is inconsistent, and the forecast never lines up good swell with clean, light wind. If you’re desperate, the Saturday morning of the 8th gives the best combo of swell and period, but it’s a long shot. The rest is a whole lot of nothing.

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.
