Alright, grab your board and listen up, it’s your local surf reporter Rusty here. I’ve got the scoop on what’s coming for us over the next couple of weeks. It’s gonna be a real test of patience, but I promise there’s a light at the end of the tunnel.
Right out of the gate, from Saturday July 4th all the way through to Monday July 13th, the surf scene is just plain flat or tiny. We’re talking about a solid week and a half of near-nothingness. Most days the energy is below 38 (weak energy), so don’t even bother dragging your board out. The water temperature is sitting at a pretty 81°F, which is about a touch warmer than normal for this time of year, so at least a swim would be nice.
The waves finally start to show a bit of life on Tuesday July 14th. On the Tuesday afternoon, the swell picks up to 3ft out of the west, with a very long 16-second period (groundswell). The combined energy jumps to a moderate 438, and the wind goes glassy. Conditions will be clean. This same pattern holds through Wednesday July 15th afternoon with a 3ft, 16-second groundswell from the west-northwest and glassy winds again (447 energy). Thursday July 16th afternoon is also worth a look, with 3ft from the WNW and a 15-second period, glassy again (292 energy). These are the best windows on offer.
After that little pulse, it fades back to tiny junk from Friday July 17th through Sunday July 19th, with energy dropping back below 200 and only a rare knee-high wave.
If we’re talking standouts, the best bet is Sixtynine itself, but only for those few afternoons. The swell direction (west to west-northwest) lines up nicely with the optimum direction for this spot. The swell is small, under three feet, so it’s friendly for the intermediate crew. The long-period groundswell means better shape and longer lulls between sets, making it easier to paddle out. The fact that it’s a pretty consistent break is a bonus.
Keep an eye on the Tuesday July 14th afternoon, the Wednesday July 15th afternoon, and the Thursday July 16th afternoon. Those glassy, clean windows with a bit of energy are your only real shot at something rideable. The rest of the 16-day run is a waiting game.

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.
