Alright folks, Rusty here. Let’s chew the fat on what’s coming up at Sixtynine.

Right off the bat, it’s a slow start. There’s a long stretch of flat or near-flat conditions that’ll have you checking your watch. Nothing worth paddling out for until mid-month. The first real glimmer of hope shows up on Tuesday the 14th, and even then, it’s a late-day call.

The standout, the one to lock in, is the afternoon of Tuesday, July 14th. The water is glassy, the wind is light and variable, and we’ve got a solid 2ft swell pushing in from the west with a very long period of 19 seconds. That’s groundswell, no doubt. The combined energy reading is 284 (moderate wave energy), so there’s some punch behind it. Sixtynine is a fairly exposed spot, and with that long-period WNW swell, it’ll wrap in nicely. Keep in mind, with a period that long, it’ll be a bit more walled up, better for a point or reef, but on a consistent break like this, it’ll offer some clean, lined-up rides. Water temps are sitting at 81°, which is a touch warmer than normal for this time of year – not a huge anomaly, but a nice little bonus.

The other window to watch is the afternoon of Thursday, July 16th. Similar story: glassy conditions, 2ft of west swell, period at 15 seconds, and the combined energy is 281. It’s a marginal call with the tide, but if you’re patient, this could be another clean session. Just keep in mind, this is a week and a half out, so the long-range forecast is a bit less certain, but the signs are promising.

Other than that, the rest of the 16-day window is a whole lot of nothing. Friday the 17th onward drops back into the doldrums with weak, jumbled energy and small, short-period waves. You’ll be waiting for sets.

Bottom line: If you can get out late on Tuesday the 14th, or Thursday the 16th, you’ll find the best of a poor run. It’s not going to be big, but it’ll be clean and glassy. For everything else, leave the board in the car.

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.
