The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the menu for Nimitz Beach.
First thing you gotta know: the water is sitting at a warm 81.7°F, which is about average for this time of year, so no surprises there.
Honestly, the next two weeks are a bit of a grind. We’ve got a real dry spell kicking off. For the first several days, from Tuesday the 25th of August right through the end of the month, the surf is basically a no-go. The swell is small, the period is short, and that cross-off wind from the ENE is blowing a fresh 22 mph. It’s clean, but the wave energy is just too weak to get excited about. The combined energy is in the 400s for most of that time, which is puny. You’ll be bobbing around on 2.3 ft to 3.3 ft slop.
The first faint glimmer of hope comes on Thursday the 27th of August. The morning shows a little bump in energy, with a 4.3 ft south swell wrapping in at a 17-second period. That’s a proper long-period groundswell. The combined energy jumps to 1093 (moderate), which is *something*, but the wind is still a cross-off at 16 mph. The break is an inconsistent reef, so it won’t be pumping, but it’s the most interesting surf of the first week. Don’t expect a crowd, but it’s a beginner spot anyway.
We then hit another lull from the 29th of August right through the 1st of September. More 2.0 ft to 2.3 ft slop, more ENE wind, and combined energy dropping back to the 300s and 400s. It’s a real flat spell.
Things start to shift around the 2nd of September. The wind eases way back to a gentle 9 mph cross-shore, and the swell starts to clean up. By the morning of the 3rd of September, we get a light onshore breeze, but the swell is still pretty weak at 2.6 ft.
The real standout, if you can call it that, is shaping up for the second week, specifically the 6th and 7th of September. On Sunday the 6th, the combined energy ramps up to 1148 (moderate) with a 3.3 ft SSW swell at a 16-second period. The wind is a gentle 9 mph cross-shore, which is about as good as it gets here. That’s clean, glassy-ish conditions with a bit of energy. Then Monday the 7th of September afternoon looks even better: a 3.6 ft SSW swell with a 15-second period, and the combined energy hits 1176. The wind drops to a light 6 mph cross-shore. That is your best bet of the whole forecast. It’s not huge, but it’s clean and has some push.
One last thing: on Tuesday the 8th of September afternoon, we see a 4.9 ft east swell come in at a 12-second period with a clean cross-off breeze. The energy is 1070 (moderate). That’s a bit of size, but for a beginner reef, and given it’s still a week and a half away, take it with a grain of salt.

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.
