Alright, folks, Rusty here. Let's not beat around the bush. The next couple of weeks are looking pretty grim for waves. We've got a long dry spell before anything worth paddling out for shows up.

We're starting off with absolutely nothing. From July 5th right through to the morning of July 12th, it’s a total write-off. Don't even bother checking the cams. We're talking about knee-high dribble at best, if you can even call it that. The wind is all over the shop, and there's just no energy in the water. The water temp is sitting at a balmy 81°F, which is a touch warmer than normal for this time of year, but that's small comfort when you're bobbing around on a flat day.

Things finally start to whisper to life on the afternoon of Sunday, July 12th. We'll see a tiny pulse of swell, 1ft from the SW, and the energy starts to creep up. By the afternoon it's clean with a light cross-offshore breeze, but it's still barely surfable. That slight lift is the only hint of life.

Then, there’s a real tease on the horizon. The standout, and I mean the only real window of half-decent surf, is shaping up around Tuesday, July 14th at Sixtynine. The afternoon session is where it's at. We're looking at a clean 3ft groundswell out of the west with a very long period of 17 seconds. That long period is going to mean proper lines, and the glassy conditions will make it look like a mirror. The combined energy is pumping. This is the one to point the car at. That said, it’s a consistent wave here, but it can get a bit of a crowd, so keep that in mind.

Wednesday the 15th and Thursday the 16th also have some potential. The afternoons both show that same 3ft W swell with glassy conditions, though the energy dips a touch. It'll be clean, fun, and probably your next best bet after that Tuesday peak.

From Friday the 17th onwards, the party fades. The swell drops back under 3ft, and the energy goes with it. The weekend of the 18th and 19th is back to weak, small surf with limited quality. The final entry on Monday the 20th shows a tiny 1ft signal, but it's hardly a call to action.

So, to sum it up: don't bother for the first week. Circle Sunday the 12th on the calendar as a maybe for a cheeky paddle, but lock in Tuesday afternoon the 14th for the best chance at a clean, glassy, proper wave. It won't be epic, but it'll be the best we get in this window. Forecasts can always change, but right now, that's the call.

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.
