The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for Nimitz Beach over the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a tough stretch. We’re looking at a long, slow grind. The first proper surfable day isn’t until the 27th, so you’re looking at nearly a week of flat, frustrating conditions before anything even gets close to worth paddling out for.
From the 21st through the 26th, it’s lean pickings. We’ve got small, weak swell in the 2ft to 3ft range, mostly from the SSW. The energy is weak to moderate (481 to 1017), and the wind is a steady cross-offshore, which keeps the surface clean, but there just isn’t enough push. The periods are long, between 14 and 24 seconds, which is nice for a groundswell, but on a reef break like this, it’s just not showing up with any punch. You’d be fighting for scraps.
The first real flicker of hope comes on Sunday the 27th. The swell bumps up to 6ft from the East, with a moderate 14-second period. The combined energy jumps to 1513, so there’s finally some decent grunt in the water. Wind is a clean cross-off from the ENE, so expect a bit of a shoulder. Monday the 28th morning looks even better on paper – 6ft from the East with a light breeze, but the tide or something is messing with the quality, keeping the score down. Still, for a surfer who’s been waiting, this is the window to get wet.
The standout for the whole run, and the one I’d circle on the calendar, is Thursday the 30th of July. The swell is only 2ft from the South, but the wind goes completely glassy. That’s a massive deal for a reef break. The energy is weak (322), but the conditions are perfect. A clean, glassy reef with a 13-second period can offer up some surprisingly fun little nuggets. This is for the patient surfer who knows the break and can milk a small wave.
After that, the first week of August looks poor. The wind picks up, the swell gets messy and short-period (8 seconds), and the conditions go downhill. There’s a tiny pulse on the 3rd with 3ft from the East and a long 16-second period, but the wind is strong and the quality is only marginal.
Bottom line: If you haven’t surfed in a week, the 27th to the 30th is your window. The real gem is the glassy morning on the 30th. Otherwise, it’s a long wait for very little reward.
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.
