The Lowdown
Howdy, Rusty here. Let’s call it like it is—this stretch ain’t gonna win any awards. We’ve only got one break in the mix, Nimitz Beach, a reef that’s inconsistent and best suited for beginners when it’s small. But for most of this 16-day run, the waves are a no-go. The water’s sitting at 81°F, with a minor anomaly of 0.7°F, so pretty average for the time of year.
We start off with a gap: nothing worth paddling out for from Sunday August 30 through Tuesday September 1. The swell is tiny, around 2ft, with a long period groundswell from the SSW that’s clean but just too weak. The combined energy is weak at 498, and it’s all labeled poor surf.
The first real chance comes on Wednesday morning September 2. The swell bumps up to 3ft from the S, period 16 seconds, with moderate energy at 602. It’s still marginal with that cross-off wind from the ENE blowing at 25 km/h, so it’s clean but not much to get excited about. Beginner-friendly size, but the inconsistency means you’ll be waiting.
Thursday September 3 drops back to 3ft and 3ft, poor again. Then Friday September 4 gets a spike: 7ft in the morning, pushing 8ft in the afternoon, from the east with a short period of 8 seconds. That’s expert territory, but the wind is howling at 40-45 km/h, cross-off, and the energy is strong (962 and 1378). It’s still poor or marginal, and with that short period, the waves will be lumpy—better suited for kite surfing than paddle surfing.
Saturday September 5 sees 6ft and 6ft with cross-shore winds and a cross-chop, making for messy conditions. The energy is high (1504 and 817), but the quality is poor. After that, it’s back to small stuff, with a few marginal blips on Tuesday September 8 morning (8ft with offshore wind from the north at 40 km/h—clean and powerful, but for experts only) and Wednesday September 9 afternoon (5ft, clean cross-off). The combined energy peaks at 1784 on the 8th morning, but it’s a strong breeze and hard to paddle into.
If I had to pick one standout, it’s the morning of Tuesday September 8 at Nimitz Beach. The swell is 8ft from the east, period 9 seconds, with offshore wind from the north at 40 km/h. That’s clean, powerful, and proper—but only for experienced surfers. The rest of the 16 days? Mostly small, weak, or windy. A few marginal sessions, but nothing to lose sleep over.
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.

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.
