The Lowdown
Alright, Rusty here. Let’s break down what Nimitz Beach is serving up over the next couple of weeks.
Right off the bat, it’s a bit of a mixed bag. The first few days have some size, but the conditions are all over the place, and we’ve got a stretch of very small, marginal surf to work through. The standout period looks like it’s going to be around September 7th, but you’ve got to pick your window carefully.
Sunday the 6th is a write-off for any serious fun. We’ve got a 6ft swell from the east, but with a fresh cross-shore wind it’s lumpy and messy – not worth paddling out for. The afternoon cleans up a touch, but the threat of storms and marginal conditions mean it’s still a pass.
Monday the 7th is where things get interesting. The morning brings a 7ft swell from the southwest with a long 14-second period – proper groundswell energy. The combined energy is strong at 3514, so there’s plenty of push. However, the wind is still cross and fresh, so it’s going to be lumpy. This is the best of the first week, but you’ll be working for it. By the afternoon, the swell jumps to 10ft – that’s expert territory – and with a fresh cross-onshore wind, it’s going to be a messy, blown-out mess. Avoid that.
From Tuesday the 8th onward, things drop off fast. The swell fades, the winds turn onshore, and we get into a real slump. Wednesday and Thursday the 9th and 10th are tiny – under 3ft – with clean conditions but barely any energy. The combined energy is weak, down around 430 and 367. It’s a quiet spell that stretches right through to the middle of the month.
The second week offers a glimmer. Around the 14th and 15th of September, we see a new pulse of long-period southwest swell – periods of 20 to 22 seconds – but the size is still only 2ft to 3ft. The energy picks up a bit (602), and the winds are clean and cross-off, but it’s just not enough to get excited about. It’s surfable but very ordinary.
The only true standout? I’d say the morning of the 7th is your best bet – 7ft from the southwest, solid energy, and if you can handle the lump, there’ll be some grunt. But honestly, this stretch is more about patience than performance.
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.
