The Lowdown
Alright, this is Rusty, and I’m lookin’ at the forecast for our area. Straight up, for the next week and a half, it’s a tough stretch. The only real spot on the radar is Nimitz Beach, a reef break that’s inconsistent and best for beginners. The water temp is sitting at 82°, which is pretty normal for this time of year – nothing weird going on there.
We’ve got a long gap of nothing good to start. From Monday the 24th of August, right through to the end of the month, it’s all poor surf and marginal calls. The wind is pumping from the ENE, mostly 15 to 22 mph, which is cross-off, but the swell is weak and messy. Monday morning the 24th shows a tiny 2 ft swell from the SSW, but it’s just poor conditions, no energy worth paddling for. The combined energy is only 394 – that’s weak, flat.
It stays like that for days. The only bit of a pulse shows up on Thursday the 27th morning, with a 4 ft swell from the S, period of 17 seconds, and a combined energy of 1105 – that’s moderate energy, and the wind is lighter at 12 mph. Clean conditions, but it’s still a marginal call. It’s the best of a bad bunch, but it’s not a standout.
The real standout, if you can wait, is way out there on Monday the 7th of September. That Monday afternoon, the wind drops to glassy – 3 mph from the WSW – and the swell is 3 ft from the SSW with a period of 15 seconds, giving a combined energy of 527. That’s glassy, clean, and the forecast says “expect very good surf conditions.” That’s the one. Then Tuesday the 8th of September afternoon looks similar, glassy again, with a 4 ft swell from the WSW, period of 12 seconds, and energy at 853. That’s your best chance. But it’s far out, so keep an eye on it.
For the rest of the run, it’s a bust. The swell in the second week is small, wind is mostly cross-off, and the energy stays below 1000. Not much to get excited about until that glassy window in the second week.
Rusty out.

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.
