The Lowdown

Alright, this is Rusty coming to you live and direct. We're looking at a pretty quiet stretch ahead at Nimitz Beach over the next 16 days. There’s a real lack of quality surf on offer here, so we gotta keep it real.

Right off the bat, the first solid chance I see is on Wednesday, August 12th. We're looking at a long-period south groundswell pumping in at 18 seconds, with waves around 4ft. The water temp is sitting at a typical 81°, which is about average for this time of year. The combined swell energy is moderate, with a reading of 1030, so there's some push there. But the wind is a fresh 22 mph cross-offshore from the ENE, which is grooming the reef clean. It's a glassy setup for the afternoon, but it’s only scoring a 2 in my book because the conditions are marginal. Crowds are possible, so you might have to share. This is about the best we've got for the first week.

Thursday the 13th sees a similar though slightly weaker morning pulse at 4ft with a 16-second period, still with that clean cross-off wind. The energy drops to 1011. After that, the surf tails off into the weekend. By Friday the 14th, it's even weaker, and the energy is falling into the moderate range.

Then we hit a rough patch. From Saturday, August 15th, the swell jumps up to a powerful 10ft to 12ft from the east, with a short, weak 9-second period. The combined energy skyrockets into the very strong range (1574 to 2405). This is big, messy, and dangerous – really only for experts, but the wind is howling at 28 to 31 mph. The setup looks more interesting for kite surfing than paddle surfing. That mess continues through Sunday the 16th with a big 8ft south-southeast swell and a risk of thunderstorms.

The rest of the period from Monday, August 17th, into the following week is mostly flat or weak. Swell heights drop well below 3ft, with periods between 13 and 18 seconds, but the energy is low (mostly in the 200s to 500s). The wind stays cross-off or light cross-shore, keeping the water clean, but there’s just no juice. The last chance for a little bump comes around Tuesday, August 25th, with a 4ft south-southwest swell and a 16-second period. The combined energy climbs back to 879, which is still only moderate, but the wind is light, so it will be clean. It’s a marginal option at best, nothing to get overly excited about.

To be honest, this is a blank run for the area. It’s typical for Nimitz to go quiet like this; forecasts can change, but for now, don't hold your breath. The best windows are the afternoon of August 12th and the morning of August 13th.

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.
