The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking at Nimitz Beach over the next couple of weeks.
First up, it’s pretty flat and weak to start. We got a bit of a pulse on Sunday morning, but it’s junky and short-period. Then we hit a real dry spell from the 3rd through to the 7th, with hardly anything showing. The water is a warm 81°, which is about normal, but that’s about the only exciting thing. It's a real test of patience.
The first week is a total bust for surf. There’s a small, weak swell on Monday the 4th, but it’s cross and chopped up, not worth the paddle out. Energy readings are low, down in the 100-300 range. We’re just looking at knee-high slop.
Into the second week, things start to pick up a little. Around the 12th and 13th, we see the swell size come up to around 3 to 4 feet, with the period stretching out a bit. The energy is now moderate, in the 700-900 range. It’s surfable, but still pretty average with that trade wind blowing across it.
Now, the main event. Mark your calendars for Monday the 17th. Overnight, a proper pulse of east swell is forecast to fill in, pushing waves up to 8 feet. The combined energy is strong, hitting 1563. The period is short, so it won’t be clean, but with light offshore winds, it’s going to be powerful and hollow. This is the standout day – but it’s strictly for the advanced crew. Too big and intense for the faint of heart. The afternoon backs off slightly but remains solid and clean.
So, to sum it up – a whole lot of nothing for the first week, then a gradual improvement, and one solid day of real, lumpy power right at the end of the window. Don't get too excited for the start, but keep an eye on the 17th.
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. 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.
