The Lowdown

Alright, let’s call it like it is. Over the next 16 days, Sixtynine is mostly flat or junk. There’s a big hole at the start, and the surf that does show up is barely worth the wax.

The first time you might even think about it is Tuesday the 14th. We’re talking a 2ft swell from the West, but with a 19-second period, so there’s some long-period groundswell in the mix. Combined energy is 251 (moderate). Problem is the wind is onshore, light but straight from the West. The water is 80°F, about normal for the year.

Wednesday the 15th is basically the same story. Swell stays around 3ft from the West, 16-second period, and the energy peaks at 310 (moderate). The morning is onshore again, but the wind is light. It’s not clean, it’s not fun, it’s just a marginal, messy day.

Thursday the 16th is the last day I’d even mention. Still a 3ft West swell, 15-second period, but the morning is onshore. The afternoon gets a light NNW wind, kicking it cross-onshore, but it’s still sloppy. Energy is dropping to 272. Not a good sign.

After that, it’s a long, slow death. The 18th delivers a tiny 2ft bump, but the energy is down to 89 (weak) and the wind is cross-on. By the 20th, the swell is gone. We get a flat spell that lasts for days, with just a few tiny, unrideable pulses on the 25th and 26th, 0.3ft from the SW, with poor winds.

There’s no standout here. No clean, good waves. The best you’ll get is the morning of the 15th, but it’s still a scratchy, marginal session. Probably better to leave the board in the car and just watch the horizon.

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.
