The Lowdown

Alright folks, Rusty here. Let's have a look at what's coming our way.

First up, we’re looking at a bit of a slow start and a very long, quiet finish. The action kicks off Tuesday the 14th and runs through to Sunday the 20th, but don't get too excited—it's a real mixed bag of small, marginal swells. After that, from Monday the 21st of July right through to the end of the outlook on the 29th, the wave energy just drops off a cliff. There are long stretches of zeros, so we’re looking at over a week of flat, or near-flat, conditions. That’s a big gap.

The best bet, and really the only standout in this whole 16-day window, is at Sixtynine. The water temperature is sitting at 80°, which is about average for this time of year.

Wednesday afternoon, 15th July is your golden ticket. We’ve got a clean 3 ft swell rolling in from the west, with a period of 15 seconds. That’s a nice long groundswell, bringing some proper energy (moderate with a reading of 302). The wind is dead glassy, which is a major positive. It’s a consistent spot, but it can get crowded sometimes, so get in early. The direction is spot on for this break.

Thursday afternoon, 16th July is also worth a look. It’s a similar story with 3 ft of west swell at 15 seconds, and the wind goes glassy again in the afternoon (energy is 272). It’s not quite as strong as the Wednesday, but it’s still a clean option.

Friday afternoon, 17th July gives you a tiny 2 ft from the west, but it’s glassy. The energy is down to 146, so it’s weak. Surfable, but very ordinary.

For the rest of the run, the swell is tiny, the wind is often onshore or cross, and the wave energy is in the double digits. Kite surfers might find something to play with on the breezier days, but for paddle surfing, it’s a write-off after the 20th. The long period on the Wednesday and Thursday will make for some nice, lined-up waves at a point or reef, but at a beach break it might just close out a bit straight.

My pick is Wednesday afternoon. It’s not a big day, but it’s clean and consistent.

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.
