The Lowdown
Alright, let’s get to it.
We’re looking at a slow couple of weeks ahead, no two ways about it. The surf is going to be small and a bit all over the place. The first few days, we're looking at some pretty marginal waves. It’s not flat, but you’re going to be fighting for anything decent. The winds are mostly cross-off, which keeps things clean-ish, but the swell is just not there. Expect a lot of close-outs and dribblers. The water temp is sitting right around 81° with a slight positive anomaly, so it’s normal for this time of year, but that’s about the only thing that's normal.
The first real whisper of anything happens around Wednesday, August 12th. We see the energy pick up a bit with a moderate energy reading (788), and the swell bumps up to 3ft from the S. It’s still pretty weak, but it’s a start. Thursday, August 13th looks slightly better, with the swell up to 4ft from the S and the energy staying strong (885). The winds are offshore in the morning, which is a big plus, and it should be clean. The period is around 16 seconds, so there's some push in it. It’s the pick of the week, but let’s not get carried away—it’s still small.
Then things back off again. Friday, August 14th sees the swell dropping and the wind becoming a strong offshore breeze, making it hard to get into the waves. The weekend is pretty poor. Energy drops right off, and the surf gets messy. The gap from the 16th to the 18th has some small, clean surf, but not much to write home about. The energy is weak (under 300), and the swell is just occasionally breaking.
The real standout is Tuesday, August 18th afternoon and Friday, August 21st afternoon. On Tuesday, August 18th, the wind turns offshore and the swell settles in at 2ft from the S with a nice 13-second period. It’s clean, and it feels like the best shape we’ve had in a while. Energy is still moderate (274), but for the conditions, this is a good looking window. Then, on Friday, August 21st, we get another similar pulse. The swell is 2ft from the SSW, but the period is back up to 16 seconds, and with the offshore wind, it should be glassy. The energy is moderate (332).
Saturday, August 22nd also looks promising. Gentle offshore winds in the morning, 2ft from the SSW, and a good long period. This is a good window for a clean, mellow session.
So, if you're looking for the best of it, aim for Thursday morning, August 13th for the biggest swell of the run, and Friday afternoon, August 21st through Saturday morning, August 22nd for the cleanest, most consistent conditions. It’s not going to be epic, but there will be some fun ones to be had.
This is Tracks (Nanakuli). The setup is a beach and reef mix. The crowds are only sometimes around, so you might get a bit more space. The offshore winds are a big deal here, and when they line up with a little bit of west in the swell, it’s magic. Just don’t expect any barrels.

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.
