Table - best surf conditions forecast for Sixtynine over the next 16 days.
Alright folks, Rusty here. Let's have a look at what's coming our way. It's a bit of a quiet picture overall, but there's one window that's worth getting a little excited about.
The opening of the period is a slow starter. There's nothing worth paddling out for on Sunday the 12th or Monday the 13th. The swell is tiny and the conditions just aren't coming together. We're looking at a gap of a few days before things start to look interesting.
The real story begins to build on Tuesday the 14th at Sixtynine. It's a fairly exposed spot, and the best winds are lining up. Tuesday afternoon is where it all clicks. We've got a 2ft swell rolling in from the west, with a long period of 16 seconds. That's a nice groundswell offering good shape and energy. The wind goes glassy – dead calm – which is a major positive for clean faces. The combined energy is moderate at 267. This is the standout of the run. For an intermediate surfer, this is the session to aim for.
Wednesday the 15th and Thursday the 16th keep the west swell going, around 3ft, with that same long period. The mornings are blown slightly offshore, but it's the afternoons that again look best. Thursday afternoon in particular sees another glassy window with clean 3ft waves. The energy is still moderate, sitting around 275. It's consistent surf for the level.
After that, the swell slowly fades through the end of the week and into the weekend. Friday the 17th and Saturday the 18th see the size drop back to 2ft and then 2ft, with the period shortening. The energy starts to dip into the weak range by Saturday the 18th, at only 89. It's surfable but ordinary.
Then we hit a long dry spell. From Sunday the 19th of July all the way through to the end of the forecast window on Monday the 27th, it's a real struggle. The swell all but disappears, with many days showing no wave height at all. The energy readings are down in the single digits or zero. There are a few tiny pulses of swell with periods up to 19 seconds on the 23rd, but at only 0.3ft, it's not going to do anything. During this stretch, there are many days with glassy or light cross-shore winds, but no wave to ride. It's a blank run that is more normal for this area when the swell windows don't line up.
Sixtynine is a consistent spot when the swell hits, but when it's flat, it's flat. The water temperature is sitting at 80°, which is about normal for this time of year, not really anything out of the ordinary.
So to wrap it up, if you've got a free afternoon, make it Tuesday the 14th. That's the one.
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.
