Alright, pull up a stump, surfers. Rusty here, and I've been staring at the charts for this stretch. Honestly, the next week or so is pretty quiet, but there's a little window in the second week that might get the blood pumping.
We're looking at a long run of flat or near-flat conditions for the first nine days. From July 3rd all the way through to the 12th, the waves are basically dialled off. You'll see tiny pulses of swell at Sixtynine, but nothing surfable – just clean, glassy water and no bump. This is a usual quiet spell for the area, so don't sweat it; it won’t stay like this forever.
The change kicks in around lunchtime on Sunday the 12th, with a small, clean 2 ft swell from the West creeping in. It’s still weak, with combined energy of only 95, so "surfable but very ordinary" sums it up. The water here is cranking at a warm 81°F with a positive anomaly of 2°F, so it's a touch warmer than normal for this time of year.
Now, the standout window is shaping up from Wednesday July 15th into Thursday July 16th. The swell builds slightly to a consistent 3 ft from the West, but the period is a solid 15 seconds. That's a proper groundswell, and those long-period waves are going to hold up best at a point break or reef setup. The real beauty here is the wind: on Wednesday afternoon and Thursday afternoon, we’re seeing a glassy state. That means perfect, clean conditions with zero wind chop. The combined swell energy is moderate, sitting between 275 and 287, which is enough to put some push in the face. This is intermediate-friendly surf – not too big, not too small, just right. This is the best surf on offer across the whole forecast, but remember, it’s well out past the first week, so treat it as a promising lead to keep an eye on.
For the end of the run into the 18th, the swell drops back down to 2 ft with glassy mornings on Saturday, making for a clean but small finish.
Alright, that’s the long-range look. Keep your eyes on that mid-month window.
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.
