The Lowdown

Alright, Rusty again. Looking at the numbers for the next couple of weeks, it's a grim stretch for Sixtynine. There's just no wave energy in the water. We're looking at a long period of flat, poor conditions.

The first little sign of life is around Thursday, July 30th. A tiny 1-foot groundswell from the southwest with a very long 18-second period creeps in. The energy is weak, only 49. The wind is light from the north, but it's a cross-shore, so it won't be clean. The swell is so small and the period so long, it's a tough one to get anything out of.

Friday, July 31st, is the same story. A 1-foot swell from the north, but the period drops to 9 seconds, which is short and weak. The energy is basically nothing (13 to 14). The wind is light and cross-shore, but the waves are just too small.

We hit the first week of August, and it's a wasteland. Saturday the 1st and Sunday the 2nd have tiny 0.6-foot to 1-foot swells with periods all over the place, but the energy is non-existent (5 to 29). The water temp is about 80°F, which is normal for the time of year, but it doesn't matter when there's no waves.

There's a moment on Monday afternoon, August 3rd, where it goes glassy with a 1-foot swell from the north, but the period is a super short 6 seconds. That's a windswell, and it'll be a messy closeout. The energy is only 15. It's a cruel tease.

The rest of the week through to August 11th is a total washout. Some glassy conditions, but the swell heights are consistently 0.3 feet to 1 feet, and the energy values are all in the low single digits or teens. There's a brief flash on August 7th (Friday) where a 1-foot westerly swell with a 14-second period gives us a slightly higher energy reading of 36, and the wind goes clean cross-off from the NE. But it's still a tiny wave. Then on August 8th (Saturday) morning, we get a 1-foot westerly swell with a 12-second period, and the energy bumps up to 45. The wind is light and cross-shore. That's the best of the worst, but it's still a knee-high wave at best.

There are no standouts here. The best option is probably the morning of August 8th, with the 1-foot, 12-second westerly swell (45 energy) and light cross-shore wind. But it's a far cry from a proper surf. The groundswell on the 30th is too long in period for a beach break, and the wind is never right. It's a tough stretch, no doubt.

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.
