The Lowdown
Alright, Rusty here again. Let's run through what's shaping up for Nimitz Beach over the next couple of weeks in feet and degrees.
Honestly, this spot isn't doing us many favours. Nimitz Beach is a pretty inconsistent reef setup, so you can't rely on it. The start of the run is tiny. Sunday the 13th has a small 2ft swell from the SW with a super long 15-second period, but the energy is weak (223). Not much to write home about.
Tuesday the 15th gives us a little spike. Tuesday afternoon brings a 3ft SSW swell with a long 19-second period. The wind goes light and glassy, turning cross-offshore, so it'll be clean. The energy picks up to moderate (524) and the conditions are called "very good". For a break that rarely breaks, that's a moment to pay attention to. You might have some company though, as crowds are possible.
From Wednesday the 16th through Thursday the 17th, the swell stays around 3-3ft, but the wind is a stiff 19 mph from the ENE. It's cross-off, so the wave faces will be clean, but it's gonna be a fight paddling out in that fresh breeze.
Looking way out, Saturday the 27th of September sees a pulse of short-period windswell from the east, about 6-6ft, with a short 8-second period. The real standout is Sunday the 27th afternoon. The swell is 6ft from the east, still short period, but the wind drops to a gentle 9 mph cross-off, and the report says "expect very good surf conditions". The water temp is about average for this time of year. This is the best on offer across the whole outlook, but it's a long way out, so don't book your flights yet. That east swell is straight onshore, so it'll be a bit dumpy and better suited to experienced surfers.
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.
