The Lowdown
Alright, Rusty here again with the imperial take. This is the whole run at Nimitz Beach and nowhere else, so we're living and dying with one break. To be fair, it’s a tough hand to play.
Right now, we’re looking at a small, drawn-out pattern. South-west groundswell is trying to show up, but it’s just not got the size or the conditions to back it up. The water temp is about 82°, which is right where it should be for this time of year, totally average.
The first few days are a slow grind. Saturday the 12th, we’ve got a tiny 2ft south-west groundswell with a real nice 16-second interval, building energy up to 256. That’s light. Wind is a light east cross-shore, so it’s a little rippled and messy. This is a reef that’s inconsistent and rarely works, and this little pulse won’t change that. It's marginal at best. Sunday gets glassy in the afternoon but the swell is a paltry 1ft – almost flat.
Monday the 14th is a washout with moderate winds. You’re looking at a couple of days of “poor” until a real moment Tuesday the 15th. That morning we get a 3ft south-west swell, period a solid 20 seconds, and combined energy jumps to 624 – that’s moderate power. The wind turns cross-offshore from the east, cleaning the faces up proper. For this inconsistent little reef break, that’s your best shot of the first week. It’s small, but it will be clean.
From the 16th through the 20th, the swell sits around 3ft to 4ft but the wind cranks up to a stiff 19 to 22 mile-per-hour breeze from the east-northeast. It stays cross-off, so it’s technically clean, but it’s a windy paddle for small waves that will feel blown out.
Then Monday the 21st of September brings a shift – the swell jumps to 6ft from the east, but it’s short period, only 7 seconds. Energy hits 685, so there’s strength, but it’s a messy windswell. At that size for a reef, you’re in expert-only territory and the 19 mile-per-hour cross-off wind makes it a real handful. That’s kite-surfing territory more than paddle surfing.
The second week trails off. The 23rd of September morning has a shot with a 6ft east swell, still short period, but the wind drops to a light 3 mph cross-on. The combined energy is high at 946, so there will be lumps, but it’ll be bumpy. After that it’s back to 3ft and relentless 19 mile-per-hour winds – just not worth it.
If you’re picking your window, it’s Tuesday the 15th morning. Small, clean, cross-off – the only good moment on a spot that doesn’t give them up easy.
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.
