The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Sixtynine.
Honestly, the next week and a half is a bit of a flat spell. We’re looking at a long stretch of poor surf conditions, with very little on offer. The first real chance of anything surfable doesn’t show up until the afternoon of Sunday, the 9th of August, and even then it’s only just barely worth a mention.
From now until that Sunday, the combined energy is almost non-existent – mostly sitting at 0, with a few ridiculously weak pulses in the 40s and 30s. The water temp is sitting at a pretty normal 80°, which is about average for the time of year.
The standout, if you can call it that, is the afternoon of Sunday, the 9th of August. The conditions are glassy, and there’s a tiny 1ft swell from the West with a period of 11 seconds. The combined energy is a weak 74, so it’s not going to be anything to write home about, but it’s the only window where the report says “surfable waves” – just very ordinary. The morning of Monday the 10th has a similar 2ft pulse from the West with a period of 13 seconds, but the wind is cross-onshore, so it’ll be crumbly. The afternoon of the 10th is cleaner with a cross-offshore breeze, but the swell is only 1ft.
There are a few bigger pulses later on, like the 2ft swell on the morning of Saturday the 8th from the West (13 seconds, 165 energy), but the wind is cross-shore and the conditions are still classed as poor. The Friday the 7th afternoon has a 2ft swell from the West (15 seconds, 109 energy) with a clean cross-offshore wind, but again, not enough to get excited about. The swell direction is from the West, which matches the optimum swell direction for Sixtynine, but the size is just too small to make any real waves.
For a break that’s fairly exposed, it’s a frustrating run. The period is decent – 11 to 15 seconds on those tiny pulses – but with such small swell heights, it’s just not happening. The water temp is normal, the wind is often light or glassy, but the swell is missing.
This is a classic case of a blank run for this area. It tends not to stay this poor for long, but for now, the only realistic option is a paddle on the 9th if you’re desperate for a bob around.
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.
