Alright, let’s break it down, surfers. Rusty here.

First up, Sixtynine – it’s a consistent little spot, intermediate-friendly, and it’s fairly exposed to the swell. The water’s sitting at 80.6° this week – that’s about a couple degrees warmer than usual for this time of year, so not a shocker, but nice. However, and I hate to say it, there’s just no good surf in the 16-day window. None. Zero recommendations. The whole run from now (7 July) through to the 22nd is mostly flat or so tiny it’s not worth paddling out for.

Let’s walk through it. Tuesday 7 July afternoon – no swell at all. Wednesday 8 July morning brings a pathetic 0.3 ft of SW swell, period 13 seconds – a long-period groundswell but barely a ripple. That pattern holds: 0.3–0.7 ft of westerly groundswell through Thursday and Friday, all with light winds but nothing to ride. The combined energy readings are all below 40 (like 7, 5, 17, 22, 31, 37) – that’s weak. By Saturday 11 July morning we see 1.3 ft from the west, period 14s, energy 112 – still small, and the wind is a moderate cross-offshore from NNE that’ll keep it clean, but there’s no power. The wave comment is “poor surf conditions” all the way until the afternoon of Monday 13 July.

That’s when we finally get a “surfable waves but very ordinary conditions” label – just a 1.0 ft from WNW with period 19 seconds (very long period) and energy 71. The wind is gentle cross-off from NE, so it’ll be clean, but that’s barely a knee-high dribble. Tuesday 14 July picks up a bit: 2.0 ft from W, period 18s, energy 222 in the morning and 222 again in the afternoon – still “very ordinary”. Wednesday 15 July morning is 2.3 ft from W, period 16s, energy 248 – the best height of the whole outlook – but it’s cross-on with a light NNW wind so it’s a little onshore. Wednesday afternoon turns glassy: 2.3 ft, 16s, energy 242 – clean but weak. Thursday 16 July morning 2.3 ft from W, 15s, energy 215 but cross-on again. The afternoon goes onshore from NW with unknown wind quality. That’s the peak of the run – and it’s still only just surfable.

From Friday 17 July onward it drops off: 2.0 ft, then 1.6 ft, then 1.3 ft, then 1.0 ft, then 0.7 ft, and by Tuesday 21 July it’s completely flat again. Glassy conditions on a few afternoons but no wave. So yeah – it’s a dry spell. The break itself is consistent according to the local knowledge, but when the swell just doesn’t show, even a consistent spot looks empty. If you’re a beginner, the tiny waves aren’t dangerous, but they’re not worth the drive. For anyone else, save your energy. The forecasts can change, but right now the next

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.
