Alright, let’s get into it. We’ve got a long stretch ahead at Sixtynine, and I’ll be honest with you – it starts off pretty flat and stays that way for a while. The first real pulse of energy doesn’t show up until early in the second week, so we’re looking at a gap of over a week with nothing worth paddling out for.
Right now, through the first few days of July, it’s dead calm. No swell to speak of, and the water’s sitting at a warm 80°, which is about a degree and a half warmer than usual for this time of year – feels nice if you’re just floating, but there’s no wave to ride. Thursday the 2nd has glassy conditions but zero surf. Friday and Saturday the 3rd and 4th are a similar story: some light morning cross-shore breeze, a tiny 1ft pulse from the SW on Saturday morning with a period of 16 seconds, but the combined energy is only 38 – that’s weak, barely a ripple.
Sunday the 5th through Wednesday the 10th is more of the same: flat, with the odd tiny 0.3ft to 1ft bump showing up, mostly from the west with periods around 10 to 14 seconds. The energy readings are low – 2 to 61 – nothing that’s going to get you excited. Winds are light and mostly cross or cross-off, but there’s just no push behind them.
Then we start to see a change around the 11th of July. Saturday morning the 11th brings a 2ft west swell with a 14-second period and the combined energy jumps to 146 – that’s moderate now, getting warmer. Winds are cross-off from the NE at 12 mph, keeping it clean. It’s still small, but it’s a sign of life.
Sunday the 12th is similar but the energy drops back to 89, and the wind goes cross-shore with a little chop. Not terrible, but not a standout.
Now, here’s where it gets interesting. On Monday the 13th, the morning shows a 2ft west swell with a 16-second period and energy of 124. But the afternoon – that’s the spark. The swell bumps up to 2ft from the west, the period stretches out to 19 seconds, and the combined energy hits 251. That’s moderate wave energy, and a 19-second period is groundswell, proper long-period stuff. That kind of period means the waves will have real shape and power, and longer gaps between sets – good for paddling out. But keep in mind, at a fairly exposed break like Sixtynine, that long period tends to break a bit too straight if it’s a beach setup, so it’s better suited for a point or reef.
Tuesday the 14th is the best on offer across the whole outlook. Morning has a 3ft west swell, 16-second period, and energy of 334 – that’s solid moderate energy. The wind is light cross-onshore from the NNW at 3 mph, so conditions are a little compromised but still surfable. The standout is Tuesday afternoon: same 3ft west swell, same 16-second period, energy of 326, and the wind switches to cross-off from the NE at 6 mph. That’s clean. The water temp is still warm, around 80°, so it’ll be a comfortable session. This is the one to circle – moderate energy, clean lines, manageable size. It’s not huge, but it’s the cleanest and most consistent window in the whole two weeks.
Wednesday the 15th holds similar size – 3ft west, 16-second period – but the wind is cross-shore and light, and the energy dips to 310. It’s still surfable, but the tide might make it a bit tricky. Not quite as good as Tuesday.
Thursday the 16th drops off: 2ft, 15-second period, energy 227, and the morning has cross-onshore wind. The afternoon glass off from the WNW at 3 mph gives you clean, glassy conditions, but the swell is fading.
Friday the 17th wraps things up with 2ft, 14-second period, energy down to 113, and a glassy afternoon but very ordinary surf.
So, to sum it up: the first 10 days or so are a write-off. Flat as a lake. Then the second week slowly builds, and Tuesday the 14th afternoon is the clear winner – 3ft west swell, 16-second period, clean cross-off wind, moderate energy (326). The Monday the 13th afternoon is also worth a look if you’re keen on the long-period groundswell (19 seconds, 2ft), but Tuesday is the more complete package. After that, it fades out.
Sixtynine is a consistent spot, so it’s a bit of a bummer to see such a long flat spell, but that’s the way it plays out this time around. Hang in there, and pencil in that Tuesday afternoon.

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.
