The Lowdown
Alright, Rusty here again. Let’s break it down in feet and miles per hour, because that’s how we feel it. The next 16 days at Nimitz Beach are looking pretty flat for a proper surf. This is a south-facing reef that’s inconsistent, and the swell just isn’t cooperating. The water is about 80°F, which is normal for the time of year.
The only real highlight is around Tuesday the 28th. On Tuesday morning, the swell hits about 6ft from the east, with a 13-second period – that’s some decent energy (1424). The wind is a gentle 9 mph from the northeast, cross-offshore, so the waves will be clean. By Tuesday afternoon, the swell bumps up to 7ft from the east, still 13 seconds, and the energy jumps to 1882. That’s a solid wave for experienced surfers, but it’s getting into expert territory at that size. Wednesday morning drops way off to 2ft, so that Tuesday afternoon is your one true standout.
After that, it’s a long stretch of poor conditions. Thursday the 30th morning has 5ft from the east, but the period is a short 8 seconds – that’s weak, windswell energy (698). The wind is okay, but the wave quality is marginal. From Friday the 31st through the first week of August, the swell is all over the place, but the wind picks up strong, mostly 19 to 25 mph from the east-northeast, and the wave heights are either too small or too messy. The energy values drop into the low hundreds or even double digits, like 42 on the 5th of August, which is barely a ripple.
There’s a gap of several days with no real recommendations from the 29th of July all the way to the 6th of August. The 6th of August morning has a tiny 4ft from the east with a 6-second period – that’s just a bump. The 7th of August morning has 5ft, but again, short period and strong wind, so it’s blown out.
Honestly, if you’re a kite surfer, the consistent cross-off winds and moderate swell on some days might look interesting, but for a paddle surfer, this is a tough stretch. The only real window to watch is Tuesday the 28th afternoon, but even that is a one-off. Forecasts can change, but right now, this is a long, quiet run for Nimitz.
Rusty.

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.
