Alright folks, Rusty here. Let's have a look at what Sixtynine has in store for us over the next couple of weeks. Honestly, it's a slow start, so don't bother waxing up just yet.
We're looking at a long dry spell. From Sunday the 5th of July right through to Monday the 13th of July, it's pretty much flat or tiny, with weak, messy energy. We're talking about a full week of poor surf conditions. The water temp is sitting at a warm 81°, a touch warmer than normal for this time of year, but that's small comfort when there's nothing to ride. The combined swell energy is hardly worth mentioning, with values mostly below 50 (12), just tiny little windswells that won't give you anything but a frustrating paddle.
Things start to look a little more interesting on Monday the 13th of July afternoon. The swell ticks up to 2ft from the W, period is 15 seconds – that's a nice, long groundswell. The combined energy jumps to 232 (moderate), and the wind goes light NE cross-off, leaving the surface clean. It's surfable but still pretty ordinary.
The standout window arrives on Tuesday the 14th of July afternoon. This is the one. The swell builds to 3ft from the W, with a very long period of 19 seconds. That's proper groundswell with heaps of push. Combined energy is a solid 441 (strong). But the real kicker? The wind goes glassy. Dead flat. Sixtynine is a fairly exposed spot, and with clean, glassy conditions and a nice little W swell wrapping in, it's going to be smooth and lined up. Just keep in mind, a long-period swell like this (19 seconds) will have long lulls between sets, making the paddle out easier, but the waves themselves might be a bit straight for a beach break – it'll be best if there's a bit of a bank or a rip to work with. For the intermediate surfer, this is the pick of the fortnight.
Wednesday the 15th of July offers another chance, with 3ft from the W and a 16-second period, and glassy winds again in the afternoon. Combined energy is still strong at 344. It's a solid backup, but the Tuesday afternoon window is the true standout.
After that, the swell slowly fades through the rest of the week and into the next. Thursday the 16th sees 2ft from the W (period 15s, energy 215), but the winds start to shift onshore or cross-onshore, so it gets a bit lumpy. Friday the 17th has a brief glassy moment in the afternoon with 2ft from the W, but the energy drops back to 146, making it just a salvage session. From Saturday the 18th onwards, it's back to tiny, weak stuff, with combined energy often below 60. The glassy conditions on Saturday afternoon are nice, but with only 1ft of swell, it's barely a hop.
So, to sum it up: the first week is a write-off. The best surf by a long shot is Tuesday afternoon, 14th July. Get on it. After that, it's a slow fade again.
Stay frothing.
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.
