The Lowdown
Alright, Rusty here. Gotta be straight with ya – this 16-day outlook for Nimitz Beach is a bit of a struggle. We're looking at a full-on week of mostly messy, blown-out conditions before things settle down. The combined swell energy is sky-high early on, hitting 4401 (very strong) on Monday the 7th, but it's all coming with a strong cross-onshore wind. That's not surf, that's a washing machine.
Honestly, the first real window where you'd even want to paddle out doesn't show up until Wednesday the 9th in the afternoon. The swell has dropped to a tiny 3 ft from the SSW, but the wind goes glassy. Combined energy is down to 296 (weak). It's small, but those brief glassy windows are precious. The water temp is sitting at 81°, which is pretty average for this time of year.
Thursday the 10th stays small, with a 2 ft SSW swell but period goes up to 16-18 seconds – that's a long-period groundswell, which can make the waves a bit straight on a reef setup like this, but the clean cross-off wind should tidy things up. Energy is moderate at around 510.
There's a tiny glimmer on Monday the 14th afternoon, with a 2 ft SSW groundswell, a very long 22-second period, and glassy conditions. That is proper clean, even if tiny. Energy is moderate (382).
Into the second week, the best bet looks like Thursday the 17th afternoon. Again, we're on a 3 ft SSW swell with a 16-second period, glassy wind, and combined energy of 413 (moderate). It's not pumping, but glassy and clean offshore at Nimitz is always worth a look. This reef break is inconsistent, so these windows are the ones to chase.
Standout pick: If I have to pick the best on offer, it's Thursday afternoon, September 17th. The forecast shows glassy conditions with that clean 3 ft SSW swell. It's small, sure, but for this stretch, that's the cleanest you're gonna get. Be aware, this spot can get crowded sometimes, so get in early for the better sets.
Towards the end of the run, Monday afternoon September 21st and Tuesday the 22nd both show glassy periods again, with a consistent 2-3 ft SSW swell and 13-14 second period. It's small, clean, and surfable.

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.
