The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.

Right off the bat, we’re looking at a pretty quiet run. The first surf worth paddling out for isn’t until Tuesday, 11th August, at Nimitz Beach. This is a reef break, so you’ve got to be a bit careful with your feet, but it’s a beginner-friendly spot. The water’s sitting at 81°, which is pretty much what you’d expect for this time of year – no major surprises there.

Tuesday 11th August sees a small, clean wave with a 3ft SSW swell pushing through. The wind is a cross-off from the ENE at 19 mph, which will keep the surface tidy. The combined energy is moderate (554). It’s not going to blow your mind, but it’s a start.

Wednesday 12th August is a bit better. The morning picks up a 3ft S swell with a very long 18-second period – that’s proper groundswell energy. The wind is a lighter cross-off at 16 mph, and the wave energy is solid (1025). This is a good one for a reef or point break, as the long period might make the waves a bit too straight for your average beach break. The afternoon is similar, with a 4ft S swell and still clean.

Thursday 13th August holds the same vibe. A 4ft S swell, 16-second period, and cross-off wind. It’s clean, but there’s a “marginal surf” tag on it, so it’s not a standout.

Now, Saturday 15th August is interesting, but maybe not for the right reasons. The swell jumps to 6ft from the east, with a period of 11 seconds. The wind is a strong 25 mph cross-off from the NE. The wave energy is strong (1144). This is getting into the size range where beginners might struggle, and with that wind, it’s going to be a bit of a battle. The afternoon sees a 8ft E swell, which is pushing into expert territory.

Sunday 16th August is a write-off. We’ve got a risk of thunderstorms, strong cross-onshore winds, and an 8ft E swell. The wave energy is very strong (1505), but the conditions are just plain messy. This is kite-surfing weather, not paddle-surfing weather.

The rest of the window from Monday 17th August through to Wednesday 26th August is a real mixed bag of small, marginal waves. The swell drops right back to 2ft to 4ft, with periods that are either very long (16-20 seconds) or very short (7 seconds). The wind is mostly cross-off or cross-shore, and the wave energy is moderate to strong, but the scores are low. Expect a lot of clean but weak surf, or a bit of chop. There’s nothing here that screams “go,” but it’s not completely flat either.

The one and only true standout is Wednesday 12th August morning. The combination of a 3ft S swell at 18 seconds, light cross-off wind, and solid energy (1025) makes for the best chance of a clean, fun, long-period wave. But remember, that long period (over 15 seconds) means it’s best at a reef or point break like Nimitz; it might break a bit too straight out on the beach. It’s not a big wave, but it’s the pick of the bunch.

So, overall, a quiet start, a couple of decent mornings next week, and then a long stretch of mediocrity. Keep your eyes peeled for changes, but don’t hold your breath.

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.
