The Lowdown
Alright, Rusty here. Let’s take a look at what’s cookin’ for the next couple weeks.
Right off the bat, I gotta be straight with ya: we’re in for a long, flat spell before anything decent shows up. The first week is gonna be a grind with tiny, weak swell. The first real surf worth paddling out for doesn’t kick in until Wednesday, August 12th.
The Early Days (August 6th – August 11th):
We’re talkin’ ankle-to-knee high waves from the SSW, with swell heights sittin’ at 1ft to 3ft. The wind stays cross-off or cross for most of this time, so it won’t be blown out, but the energy is weak – combined swell energy is around 81 to 269 (weak to moderate). The water temp is 81°F, which is about average for this time of year, so no surprises there. Honestly, it’s a good week to wax your board and watch the horizon. The crowds at Tracks (Nanakuli) might be around sometimes, but with waves this small, most folks will be on the beach.
The Pick of the Fortnight (Wednesday, August 12th – Morning):
This is where it gets interesting. Wednesday morning, August 12th, we see the swell bump up to 3ft from the S, with a period of 18 seconds. That’s a proper groundswell – longer period means more energy and better shape. The combined energy jumps to 857 (moderate to strong). Wind is cross-off from the ENE at 9 mph, keeping it clean. This is your standout session. Tracks (Nanakuli) is exposed to the W, and the optimum swell direction is W, so this S swell might not be hitting perfectly, but the size and quality will still offer some fun ones. The water temp is still about average.
The Rest of the Second Week (August 13th – August 18th):
We get a slow fade. Swell heights drop from 4ft on the 13th back down to 2ft by the 17th. Winds pick up, especially from the 14th onward, with gusts up to 22 mph from the ENE. Those stronger winds will chop things up, and the combined energy drops back to weak-to-moderate levels (131–536). By Tuesday morning, August 18th, we get a little glassy moment with light ESE winds at 3 mph, but the swell is tiny again at 2ft. Not much to write home about.
The Final Days (August 19th – August 21st):
Small and weak again. Swell heights 1ft to 2ft from the SW or SSW, with periods around 14–18 seconds. Winds stay cross-off but often fresh, and the combined energy is moderate at best (128–328). Crowds might be around sometimes, but there’s nothing to fight over.
So, to wrap it up: if you’ve got one day to make it happen, aim for the morning of Wednesday, August 12th. That’s the best we’ve got. Everything else is a waiting game.

Information about the Tracks (Nanakuli) Surf forecast
The above surf forecast table for Tracks (Nanakuli) provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tracks (Nanakuli) can be found by selecting the local surf guide option on the grey menu.

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 Tracks (Nanakuli) 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.
