The Lowdown

G’day, Rusty here. Let’s be straight with you – the next week and a half is a tough stretch for anyone looking to paddle out at Sixtynine. We’ve got a real dry spell on our hands.

Right now, through until the end of July, there’s basically nothing. Zero energy. The water temp is sitting at 80°, which is a little warmer than usual for this time of year, but you won’t care about that because there’s no surf to enjoy. The winds are mostly cross or cross-onshore, not helping at all. You’re looking at a solid 10 days of flat, poor surf conditions. Not a single wave worth chasing.

Then, right around the start of the second week, we finally see a pulse. On Thursday the 30th of July, a tiny 1.0ft south-west swell creeps in with a very long period of 18 seconds. The combined energy is still weak at (49). It’s small, it’s there, but the forecast calls it poor surf. The wind is light onshore or cross, so not clean. Not the one.

Moving into the first week of August, it stays small and messy. By Saturday the 8th of August, we get a glimmer. The afternoon shows a glassy session with a 2ft west swell, period 16 seconds, and the energy jumps up to moderate at (168). The wind goes glassy, and that’s a major positive. It’s the first real chance at a clean wave, but the size is tiny – only for the lightest longboard or a funboard.

The standout window hits Sunday the 9th of August. Sunday afternoon, we see 3ft west swell, a very long 16 second period, combined energy at (339) – that’s moderate and building. And the wind? Glassy. That’s the pick of the forecast. The swell direction is west, and the optimum swell direction for Sixtynine is west-northwest, so it’s a good match. The waves will be clean, with that long groundswell offering proper shape. For a break that’s fairly exposed, this is the session to target. Just keep in mind that long period swells can make beach breaks a bit straight, but Sixtynine handles it well. The vibe is quiet, crowds are only sometimes, so you might have it to yourself.

Monday the 10th of August holds similar size – 3ft west swell, 15 second period, energy still strong at (362) – but the wind goes cross-shore, so it’s not as clean as Sunday. Still surfable, but Sunday is the day.

So, to wrap it up: the first 10 days are a write-off. Hang tight. Sunday the 9th of August afternoon is your best bet – glassy, clean, with a proper west swell. It’s not huge, but it’s the best on offer. Get out there.

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.
