The Lowdown

Alright, Rusty here. Let’s have a look at what’s on offer for Sixtynine over the next couple of weeks.

Right out the gate, I’ve got to be straight with you – this stretch is a tough one. We’re looking at a long, quiet run with barely a ripple for the first ten days. The wait goes all the way from Sunday the 9th through to late Tuesday the 18th, with nothing but flat, poor conditions.

Things finally start to show a tiny pulse on the afternoon of Wednesday the 19th of August. The swell bumps up to a measly 2 ft from the west with a 12-second period, and the combined energy is a weak 73. It’s small, but the wind goes glassy, so if you absolutely need to get wet, it’ll be surfable, just very ordinary. That’s the first real sniff of a wave. The water temp is about average for this time of year, nothing unusual.

After that, Thursday the 20th and Friday the 21st offer a few more windows with glassy conditions in the afternoons, but the swell stays tiny, around 1.0 ft to 1 ft from the west-northwest. The energy is weak (40 or less). It’s clean, but tiny.

Heading into Saturday the 22nd and Sunday the 23rd, the wind picks up from the north-northeast, cross-shore, and the wave heights drop back to 1.0 ft or less. It’s a bit bumpy and messy. The run fades out through Monday the 24th with the same small, crossed-up conditions.

Honestly, there is no standout here. The best on offer is the glassy, clean window on Wednesday afternoon the 19th, and maybe a similar window on Thursday afternoon the 20th, but you’re chasing ankle-biters. For a spot that is fairly consistent, this is a rough patch. Don’t get too hung up – it tends not to stay this poor for long, and forecasts can change.

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.
