The Lowdown
Alright folks, Rusty here with a look at what’s heading our way for Nimitz Beach over the next couple of weeks. Let's get straight into it.
The next 16 days are a mixed bag, but honestly, we’re looking at a lot of marginal to poor conditions. The immediate forecast doesn't hold much for the eager beaver. We have a long stretch of small, frustrating surf ahead, with the first real chance of anything decent being pushed out to the second week.
Don’t expect much for Monday afternoon. There’s a small 2ft SSW groundswell rolling in, with a long 15-second period, but it’s up against a brisk 16 mph cross-offshore wind. The water is a warm 81°, which is about average for this time of year. The energy is weak (472), and the forecast says it's marginal at best.
Tuesday and Wednesday continue the theme of small, short-period swell from the south, with moderate wind keeping things average. Thursday and Friday see the swell nudging up to 3-4ft from the south, and there is a significant jump in energy on Wednesday and Thursday, hitting over 1000 (1025 and 1142). However, the wind is moderate to fresh cross-offshore, and the guidance still calls it marginal. It's not firing.
The only real standout – and I mean the *only* one worth marking on your calendar – is shaping up for Saturday, August 15th. We have a jump in swell size, with morning waves around 7ft from the east, building to 8ft in the afternoon, with a period of 12-13 seconds. The combined energy is strong (1660 and 2497). This is a solid, powerful swell. The wind stays cross-offshore at 19-22 mph. This is one for experienced surfers only; it's too big for beginners. It’s the best on offer, but don't expect it to be perfect.
From Sunday, August 16th, it all falls apart. A gale-force SSE wind with risk of thunderstorms completely blows out the surf. Conditions stay poor or marginal through to the end of the period, with a few tiny, clean days around August 22nd but with almost no height (2ft). There’s a brief glimmer on August 25th with a 4ft S swell and moderate energy (1044), but the wind is up again. For now, it’s a waiting game.
Take it easy,
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.

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.
