The Lowdown
Alright folks, it’s Rusty here with a look at the next 16 days for Nimitz Beach. I gotta be straight with you right off the bat – it ain’t looking like a world-class stretch, but there are a few windows where you could get a little slide.
Right now, we’re in a bit of a flat spell with small, tricky conditions. The first real bit of hope shows up on the Monday morning of the 20th of July. The water temp is about average for this time of year, so no surprises there. We’ve got a tiny 2ft swell from the south, but it’s a long-period groundswell at 16 seconds. That long period means the waves will have shape, but on a reef break like this, it could be a bit too straight. The combined energy is moderate at 397, and the wind is a cross-off shore breeze, which will keep the surface clean. It's beginner-friendly size, but it’s inconsistent, so you’ll be waiting for the sets.
The pick of the first week, and honestly the best on offer, is the morning of the 27th of July. Not a massive day, but the swell is a clean 5ft from the east with a moderate combined energy of 1292. The wind is light and cross-off, so the face will be glassy. The period is a solid 14 seconds, giving the waves some punch. It’s still small enough for most surfers, but the quality will be there. Expect a few other folks out though, as crowds are possible here.
Things get a bit more interesting around the 31st of July and the 1st of August. The morning of the 31st sees a 3ft south-southwest swell with a 16-second period. The wind is light and cross-shore, so it’ll be a bit bumpy but rideable. The 1st of August morning is a similar story with a 3ft south-southwest swell, but the wind is a bit stronger and more cross-shore, making for a choppier surface. These are marginal days, but if you’re keen, there’s a wave to be had.
A long-range standout to keep an eye on is the morning of the 4th of August. The forecast shows a 2ft south-southwest swell with a very long 18-second period. That’s proper groundswell energy, and the combined energy is a moderate 477. The wind is a fresh cross-off, so the surface should be clean. It’s small, but with that period, it could offer some surprisingly fun lines on the reef. Don’t book your flights yet, but it’s a promising note to end the run on.
So, the story is a slow start, a decent window late in the first week, and a few marginal but possible days after that. It’s not going to be epic, but there’s enough to keep the stoke alive if you’re patient.
Rusty.

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.
