The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Sixtynine over the next couple of weeks.
Honestly, it's a bit of a quiet stretch for Sixtynine. There's no real swell to speak of at the start, and we're looking at a few days of nothing much before anything even shows up. The first real sniff of action comes on Tuesday the 14th.
The standout moment is Tuesday afternoon, the 14th of July. It's not going to be big, but the conditions line up. We've got a 2ft swell rolling in from the west, with a long period of 16 seconds, giving it some real push for its size. The combined wave energy is moderate at 267. But the best part? The wind goes glassy from the WSW, and that's a major positive for Sixtynine. It'll be clean, smooth, and well-shaped for an intermediate. The water temperature is sitting at 80°, which is about average for this time of year, so no surprises there.
That Tuesday morning is a bit of a write-off with a cross-on wind, but by the afternoon, it's the best you're going to get. Wednesday the 15th through Thursday the 16th sees the swell holding around 3ft from the west, but the wind is onshore, so the quality will be marginal at best. It's surfable, but you'll be working for it.
After that, the swell fades fast. We're looking at small, weak stuff from Friday the 17th onwards, with wave energy dropping into the double digits. There's a small window on Saturday the 18th afternoon with a glassy 2ft, but it's pretty ordinary. From Sunday the 19th, it's a long stretch of tiny waves or flat spells, with a few days of absolutely no swell at all around the 21st to the 25th.
A tiny pulse tries to show up again on the 26th of July, but it's barely 0.7ft with onshore wind. Not worth getting excited about. The 28th of July has a similar 1.0ft, but it's onshore and junk.
So, for the whole 16 days, your one true call is Tuesday afternoon, 14th July. Get on it if you can, because after that, Sixtynine goes to sleep.
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.
