Table - best surf conditions forecast for Sixtynine over the next 16 days.
G’day, Rusty here. Let’s have a look at Sixtynine over the next couple of weeks.
To be honest, mate, it’s a pretty grim run. The first few days are a write-off. We’re looking at tiny, weak swells with cross-shore winds and poor conditions right through the first week. The water temp is sitting around 80° – pretty much normal for this time of year, so at least you won’t freeze.
The first real glimmer comes on Wednesday, July 15. The morning is still marginal, but the Wednesday afternoon session is where it’s at. The swell bumps up to 3ft from the west, with a period of 15 seconds – that’s a proper long-period groundswell, so expect clean, lined-up waves with good energy. The wind goes glassy, which is a huge plus. The combined energy hits 302 (moderate), so there’s some push. This is the standout window of the whole outlook. The break is fairly exposed and picks up WNW swell best, so that west direction is pretty close to perfect. Crowds are listed as “sometimes”, so you might have a few others out, but nothing crazy.
Thursday, July 16 afternoon also looks decent – same 3ft west swell, glassy wind, and 298 energy. Another good chance to get a few.
After that, it fades quickly. Friday July 17 and Saturday July 18 have smaller waves and only glassy windows for tiny, ordinary surf. Then from Sunday July 19 right through to the end of the outlook on Saturday July 25, it’s pretty much all poor surf with tiny waves under 2ft and weak energy. There’s a few glassy patches, but nothing worth paddling out for.
So, bottom line: the only real chance for a proper surf is Wednesday July 15 afternoon and maybe Thursday July 16 afternoon. Otherwise, it’s a long flat spell. Keep an eye on the forecasts, but don’t hold your breath.
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.
