The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got one spot on the radar for the next couple of weeks, and it’s a mixed bag, so let’s break it down.
The window opens with a little bit of swell, but honestly, the first few days are a tough sell. The forecast is calling for a lot of onshore and cross-off breezes that are just going to mess with the surface. The real standout, the one that’s got me talking, is Sunday afternoon, September 6th. That’s when we get a bit of a magic window. The wind is gonna ease right off, turning into a gentle cross-off breeze, and the waves are going to be a solid 6ft with a good 12-second period. The combined swell energy is cranking at 2400 (moderate to strong), and the water is a warm 81°, which is pretty average for this time of year. That’s the session to aim for, but it’s only for the experienced crew – the swell is solid.
Before that, we’ve got some lumpy, cross-shore chop on the weekend, nothing to write home about. Then, after that Sunday, things get heavy. Monday, September 7th sees a massive spike in swell, with waves jumping to 12ft and then 18ft, but it comes with a howling cross-on wind that’s going to make it a complete washing machine. That’s strictly for the kamikaze crew or maybe the kite surfers, definitely not for paddling. The energy on that afternoon is a beastly 12469 (very strong).
After that big pulse, the week drops off into a long, flat spell. From Tuesday the 8th through to the 13th, we’re looking at tiny waves, mostly under 3ft, with periods all over the place. The wind stays mostly cross-off, but the swell is just too weak and inconsistent to bother. The energy values drop right down, some sessions barely hitting 118 (weak). It’s a real dead patch.
The second week shows a few flickers of life, but it’s all uncertain. Around Monday, September 14th and Tuesday, September 15th, we get a pulse of long-period groundswell (18-21 seconds) from the SW, but the wave heights are only around 3ft. The energy is moderate (around 900), but those super long periods mean the waves will be very straight and fat at a beach break like Nimitz. It’s a promising sign for the reefs or points, but for this spot, it’s more of a tease. The wind stays clean, but the swell just isn’t tall enough to be fun. The rest of the 16-day window trickles out with small, clean but weak surf.
So, to sum it up: the only real standout is that Sunday afternoon. Get on it if you’re experienced. Otherwise, it’s a long wait.
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.
