The Lowdown
Alright, mates, Rusty here. Let’s be straight with you—looking at Sixtynine over the next couple of weeks, we’ve got a long, flat spell on our hands before anything even thinks about breaking. The good news? There’s a pulse of energy showing up in the back half, but it’s not going to be a classic. Let’s break it down.
Right now, and for the first week, it’s pretty grim. We’re seeing nothing but tiny, messy dribbles—waist-high at the absolute best, and that’s being generous. The water temp is running about average for this time of year, so no surprises there, but you’ll be paddling around more than surfing. From Sunday the 3rd all the way through to Friday the 9th, it’s a whole lot of nothing, with swell heights barely cracking 1ft and periods that are all over the shop. A few glassy moments in the afternoons—that Monday the 3rd and Thursday the 6th had some clean windows—but with no real swell behind it, it’s just not worth getting the board wet. You’d be chasing shadows.
The first real sign of life shows up on Sunday the 9th. We get a slight bump in size, around 1ft, with a period stretching out to 16 seconds. It’s still weak, energy reading at 80, and the conditions are pretty ordinary. A couple of glimmers here and there, but nothing to write home about.
Now, the second week is where things start to get a bit more interesting, but it’s still far from firing. From the 13th onwards, we see a gradual push in size. That WNW swell starts to fill in properly, and by Thursday the 14th we’re looking at close to 3ft of swell with a solid 16-second period. The energy really starts to build too—we’re talking 427 on Thursday morning, jumping to 509 by the afternoon. That’s a proper push of groundswell. The downside? The winds are mostly cross-onshore, keeping things a bit lumpy. It’s surfable, but you’ll be working for it.
Here’s where the standout finally shows its face: Saturday the 15th afternoon. We’ve got a clean 3ft of WNW groundswell, period still hanging in there at 15 seconds, and the wind drops right off to glass. That’s the best window of the whole forecast. The energy reading sits at 395, which is solid, and it’s the one time the conditions and the swell actually line up. Crowds are sometimes a thing here, so you might have some company, but for the first time in a while, Sixtynine will actually be worth the paddle out. Just keep in mind that long-period swell and beach breaks can get a bit weird—it might close out in sections, but there’ll be some proper waves in there.
After that, we’ve got Monday the 17th still showing a pulse—3ft, WNW, with a period of 14 seconds—but the wind swings onshore again, so it’ll be messier. Still, it’s more surf than we’ve seen in over a week, so if you missed Saturday, that’s your backup.
So, bottom line: the first week is a washout. Don’t even bother checking the cam. The action is all in the second week, and Saturday the 15th afternoon is your clear pick. It’s not going to be a world-class day, but after all that flatness, it’ll feel like a gift.
Stay stoked,
Rusty

Information about the Sixtynine Surf forecast
The above surf forecast table for Sixtynine provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sixtynine can be found by selecting the local surf guide option on the grey menu. Our Sixtynine 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 (Sixtynine) 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 Sixtynine 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.
Sixtynine is 84 km (52 miles) from Hilo. If you plan a vacation in Big Island, look for hotels and other accommodation in Hilo. Hilo has rooms for a wide range of budgets as well as car hire and transport links.
