The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for Nimitz Beach over the next couple of weeks. I gotta be straight with you – it's a rocky start. We're looking at a real quiet spell for the first week or so, with not much to get excited about.
The water here is sitting at a warm 82°, which is about normal for this time of year, so no surprises there.
Okay, so for the first week, from Sunday the 23rd through to Sunday the 30th of August, we're dealing with a lot of poor surf. The swell is tiny, mostly around 2ft to 5ft, but it's coming from a mix of directions with short periods. The wind is a constant issue – a fresh breeze from the east-northeast keeping it cross-offshore, which is clean, but the energy just isn't there. The combined swell energy is weak, bouncing around the 300s and 400s, with a few peaks in the 500s and 600s. It's a whole lot of paddling for nothing. This spot is a reef, and it's inconsistent, so this blank run is a bit more normal for the area. The tides and conditions are just off.
We start to see a little life on the 1st of September, Tuesday morning. A light breeze from the east, cross-shore, with a 3ft SSW groundswell at a long 18 seconds. The combined energy jumps to 681, which is in the moderate range. It's still a marginal call, but it's a hint of what's to come. The afternoon gets choppy with a storm risk, so that window is tight.
Then things pick up a notch. The 4th and 5th of September look better. On Friday the 4th morning, we get a 6ft east swell, period at 8 seconds, with a cross-offshore breeze. The energy is building (894). Saturday the 5th is the real standout. Both morning and afternoon see a solid 6ft east swell, with a longer period of 14 seconds. The wind is a clean cross-offshore, and the energy is strong – 1588 and 1569. This is a proper groundswell. At 6ft, it's getting into the intermediate zone, but it's still clean. The swell direction is east, which is the optimum direction for this spot. This is the best on offer, but remember, it's a long way out, so treat it as promising but not locked in. The 6ft east swell continues into Sunday the 6th, with energy peaking at 1681. Still clean.
But the best of the whole run? That's Monday the 7th of September. Monday morning, the wind goes glassy – totally calm. A 4ft SSW swell with a very long period of 18 seconds. The combined energy is a solid 860. The conditions are rated as "very good." This is a reef break, so that long-period groundswell will wrap in beautifully. The size is manageable for most. It's a one-off morning window, but if you can get out there, it's the cleanest, most promising session of the whole forecast. The afternoon gets a slight onshore breeze, so the morning is your window.
Don't expect much else. The rest of the second week is a mix of poor and marginal with fresh winds. It's a waiting game.
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.
