The Lowdown
Alright folks, Rusty here, and I won’t sugarcoat it – the next couple of weeks at Nimitz Beach are a real test of patience.
We’re looking at about a two-week stretch of poor to marginal surf before anything worth paddling out for shows up. The water temp is around 81°F, pretty much average for this time of year.
The first weekend, Friday September 4th through Sunday the 6th, brings some south and east swell in the 4 to 6 foot range, with moderate energy. But the wind is blowing 15 to 19 mph out of the east-northeast, keeping it cross-offshore. The waves are clean but just not that good – marginal conditions with a swell period around 12 to 14 seconds. Not enough oomph.
Monday the 7th gets ugly. A southwest swell builds to nearly 8 feet in the morning with strong energy, but the wind shifts to the east-southeast, creating a cross-shore chop. By afternoon, the swell hits 11 feet with even more power, but the onshore wind is howling at 22 mph – total mess. That’s kite or foil territory only.
From Tuesday the 8th through the middle of the month, it’s a slow decline. Wave heights drop fast to 6 feet, then smaller, with onshore winds and lumpy conditions. By the 10th, we’re down to 2-foot waves with super long periods (16 to 18 seconds) but almost no energy – combined energy readings under 200. The water goes flat and sleepy. The wind stays cross-off from the east-northeast for most of it, keeping the surface clean, but there’s just no swell to ride.
Around the 15th, we see a tiny uptick to 3-foot waves with a 21-second period, but the energy is still weak – under 900. The wind is moderate cross-off or cross-shore, and the waves are just not lining up for the reef.
Now, here’s the one bright spot: Saturday, September 19th. A south-southwest swell comes through at 3 to 4 feet with a 16-second period and moderate energy. The wind is glassy – near zero from the south-southwest. That means clean, smooth conditions. The forecast says “expect very good surf conditions,” and for this entire 16-day stretch, that’s your day. It’s not huge, but it’ll be clean, well-shaped, and uncrowded.
So, to sum it up: we’ve got a two-week gap of mostly flatness, then a solid Saturday on the 19th. If you can wait, that’s your window. Otherwise, save the energy.
Rusty.

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.
