The Lowdown
## Imperial
Alright, surfers, Rusty here again, and I’ll be honest – it’s looking like a pretty bleak stretch for the next couple of weeks. We’ve got just the one spot to talk about, and it’s a finicky one.
The only break in the forecast is Nimitz Beach, a reef that’s inconsistent and more of a beginner’s zone. The water’s at 81°F, which is pretty normal for this time of year, so at least you’ll be warm while you’re waiting for a wave.
The first week is a total bust. From Friday, August 7th, all the way through the next week, the surf is barely a ripple. The swell is tiny, mostly under 3 ft, with a constant cross-off wind from the ENE blowing at 18 mph or more. The combined energy is weak, rarely getting past 500 (moderate), and the swell is coming from the SSW or S, which isn’t the spot’s best direction. The reef might be clean, but the waves are just too small and weak to even bother with.
Things start to shift a bit on Wednesday, August 12th. The combined energy jumps to 1057 (strong) with a 3 ft S swell at 18 seconds. That’s a long-period groundswell, but the wind is still cross-off at 18 mph. The waves will be there, but the wind will give them a bit of a rough edge. By Thursday and Friday, the swell hits 4 ft, and by Saturday the 15th, it’s up to 7 ft from the E with a short period of 8 seconds. That’s a messy, choppy mess, and with the wind howling at 28 to 31 mph, it’s more of a kite-surfing session than a paddle. Not for the faint of heart.
The one real standout, if you can call it that, is Wednesday, August 12th in the morning. A 3 ft S swell with a 18-second period, strong energy (1057), and cross-off winds. The swell direction isn’t perfect, but the long period should give it some shape. It’s still a marginal call, but if you’re itching for a paddle, that’s your best bet. The rest of the run is a write-off.
So, a long, quiet stretch with one small glimmer of hope. Tough times, but that’s the ocean for you.
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.
