The Lowdown

Alright, Rusty here. Let's have a look at what's on the menu for Nimitz Beach over the next couple of weeks.

Honestly, the outlook is a bit of a slow burn. For the first week and a half, we're looking at a whole lot of marginal conditions. The surf is small, and while the winds are often cross-offshore, the wave quality just isn't there for a proper paddle session. There's a real gap from Saturday, July 18th, through to Thursday, July 23rd, where the score is a flat zero – the energy is there, but the conditions are just plain poor. It's a frustrating stretch.

The first real glimmer of hope doesn't come until Friday morning, July 24th. We finally see a slight uptick in quality with a 3ft SSW groundswell, period a solid 18 seconds, and the combined energy hits a moderate 907. The cross-offshore breeze from the ENE at 12 mph should keep things clean. It's still marginal, but it's the best we've seen in days.

The real standout, though, is shaping up for the final week of July. Monday, July 27th, through Wednesday, July 29th, is where you want to be watching. Monday morning sees a 4ft easterly swell with a long 16-second period, and the energy is strong at 1269. Tuesday is the big one: a 7ft east swell, 14-second period, with a massive combined energy of 1988. That's a serious amount of power. However, at that size, this is strictly for experienced surfers only. The cross-offshore wind from the ENE keeps it clean, but that's a lot of water moving. Wednesday morning is still solid at 6ft, but the energy drops off a cliff by Wednesday afternoon.

For the best bet, I'd have to go with Tuesday, July 28th, morning. The 7ft swell from the east is the biggest and most powerful of the entire run, and with the ENE cross-offshore breeze at 12 mph, it should be clean. The 14-second period gives it real punch. Just remember, it's a heavy day for experts only.

The water temperature is sitting at 80°F, which is about normal for this time of year, so a wetsuit is a no-go.

But after that Wednesday peak, it fades back to tiny, poor surf through the end of the month and into August. The first of August offers a glassy morning with a 2ft SSW swell, but it's going to be small and weak.

So, to sum it up: you've got a long wait for some decent waves. The best window is the last few days of July, with Tuesday morning the clear standout. Get on it if you're an expert, but be patient.

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.
