The Lowdown

Right now, we’re looking at a pretty flat start. The first surfable waves aren’t due until Sunday afternoon, September 27th, and even then it’s barely a ripple. Up until that point, it’s a long stretch of next to nothing—days and days of zero energy, just tiny wind bumps that aren’t worth paddling for.

The only spot with any pulse is Sixtynine. It’s a fairly exposed, consistent break that picks up WNW swell, but it’s been dead for almost two weeks straight. The water temp is sitting at 82°F and that’s about a degree and a half warmer than usual for this time of year—so the ocean’s got that bathwater feel.

Finally, on Sunday the 27th afternoon, there’s a faint sign of life. Swell comes through at 1.0ft from the WNW with a long period of 16 seconds. That’s a proper groundswell, long gaps between sets, which at a beach setup like this could mean it breaks a little too straight. The wind goes glassy, which is a beautiful thing for clean faces. Combined energy is sitting at 74 (weak), so it’s not going to light the world on fire, but it’s the only moment in the entire 16-day window where the wave comment even says “surfable.”

Monday the 28th morning shows a tiny 1ft from the same direction, period dropping to 15 seconds, but wind is cross-onshore so it won’t be as clean. Afternoon glass-off again, energy similar, still very small.

Let’s be real: the standout here is that Sunday afternoon glass-off session on the 27th. It’s not going to be pumping, but if you need to get wet, that’s the window. The rest of the run is flat, with weak energy readings under 100 for the entire forecast. This break doesn’t often stay poor this long, so things could shift, but as it stands, patience is the name of the game.

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.
