The Lowdown
Alright, grab a coffee and listen up. Rusty here, and I’ve been staring at the charts for Nimitz Beach. It’s a bit of a mixed bag, honestly. The next couple of weeks are looking pretty slim for any proper surf, but we’ve got a little window of hope right at the end of the run.
Right now, the reef is seeing a bit of pulse, but the conditions are making it tough. Thursday the 30th into Friday the 31st of July, we’ve got a small, weak 3ft S swell with a moderate 14 second period, but the wind is a stiff cross-off or cross breeze. The wave energy is sitting at 441 (moderate), but it’s just not clean enough to get excited about. Friday afternoon sees a short, fat 6ft E swell with a period of only 8 seconds, and the combo of a strong breeze and high energy (948) makes it a lumpy mess. Not worth paddling out for.
You’re looking at a real blank run here. From the end of July all the way through to the 9th of August, it’s poor to marginal. A few days in there, like Tuesday the 4th of August, we get glassy conditions with a whisper of a 1ft SSW swell, but it’s tiny and the energy is a paltry 70. That’s just a splash, not a wave. The water temperature is a warm 80°, which is about normal for this time of year, so at least the paddle won’t be cold.
Now, here’s the one true standout. Circle the 10th and 11th of August on your calendar. Monday the 10th afternoon, we’ve got a glassy, clean 3ft SSW swell with a 16 second period. The energy is strong at 714, and the wind is absolute glass. The same vibe continues into Tuesday the 11th of August, with glassy conditions and a 3ft S swell at 15 seconds. This is the best on offer by a long shot. That long period means the waves will have proper shape and power, and with the wind flat, it’ll be a treat. The reef setup at Nimitz should handle that south swell direction beautifully. Keep in mind that the crowds here are *sometimes* an issue, so if you can get out there early on Monday, you’ll have it dialed. This is a real gem to finish the run.
So, the bottom line: a long, dry spell until the second week of August, then a genuine glassy, clean window. Don’t hold your breath for the first week, but that Monday and Tuesday are worth the 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. 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.
