The Lowdown
Alright folks, Rusty here. Let’s get into it.
First off, the only game in town for the next couple of weeks is Nimitz Beach. It’s a reef setup, exposed to the south swell, but it’s inconsistent and more of a beginner-friendly wave. Water temp is sitting at 80°F, which is about average for this time of year, so nothing unusual there.
The outlook kicks off Monday afternoon, July 13th, but it’s pretty tame. We’ve got a 3ft south-west swell with a long 15-second period, which is a classic groundswell. That long period means the waves will have some shape and energy, but the combined energy is moderate at 676. The wind is a cross-off from the ENE at 15 mph, which will keep things clean. It’s a bit marginal overall, though.
Tuesday morning, July 14th, looks like the real standout. The swell drops slightly to 2ft from the west with a 16-second period, and the wind is light from the NE at 6 mph, staying cross-off. That makes for clean, glassy conditions. The wave comment says "expect very good surf conditions," and the combined energy is still moderate at 676. If you’re gonna paddle out, this is the session to aim for. The afternoon stays clean but the wind picks up to 12 mph, so not as good.
From Wednesday July 15th through to the start of the second week, it’s a pretty poor run. The swell stays small, winds shift cross-shore, and the scores are low. The water gets a bit choppy at times, and the combined energy drops. There’s not much to get excited about. The swell wraps around from the west and south-west, but the period stays long, which is good for this reef, but the conditions just aren’t there.
Come Monday July 20th, we see a bit of a bump. The morning brings a 3ft south swell, 16-second period, with a clean cross-off wind from the ENE at 15 mph. The combined energy jumps back up to 627, but it’s still only a marginal call. The next few days are more of the same: knee-to-waist high, clean but not great.
The end of the month, from July 27th onward, looks rough. Winds turn onshore from the SE and south, with rain and thunderstorms possible. The swell drops to 1ft and the combined energy plummets to 134. That’s essentially flat, with poor conditions.
The call: If you want the best of a quiet period, hit Tuesday morning July 14th at Nimitz Beach. It’s the only real standout – clean, glassy, and a long-period groundswell that’ll give you some fun little waves. Otherwise, it’s a long, quiet stretch.
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.
