The Lowdown
Right then, folks, Rusty here. Let’s have a look at what’s cookin’ for Kiholo Bay over the next couple of weeks.
Honestly, it’s a bit of a slow burner. For the first ten days, we’re looking at a whole lot of flatness and poor conditions. The swell energy is basically non-existent, with readings like 0 or just a few measly points of energy. There’s a few days where the wind goes glassy, like Saturday afternoon the 1st of August and Sunday afternoon the 2nd, but there’s just no push in the water to get excited about. It’s a real bust for the paddle crew.
The water temp is sitting at 81°, which is about average for this time of year, so at least it’ll be warm while you’re waiting for something to show up.
Now, we finally get a little flicker of life on Saturday the 8th of August. The morning sees a 2ft swell from the West with a 12-second period, and the energy has climbed up to a moderate 150. The wind is glassy, so the conditions will be clean. It’s surfable, but it’s ordinary – just not a lot of grunt behind it. The same goes for Saturday afternoon, with similar 2ft West swell and glassy conditions. It’s the best we’ve got, but it’s not a standout.
The following week is a bit of a mixed bag. Sunday the 9th shows a 2ft West swell at 14 seconds, which is a long period groundswell, but the wind is variable. The combined energy hits 157, which is moderate, but the conditions are still poor. The standout for the whole outlook, if you can call it that, might be Monday the 10th of August. The afternoon sees a 3ft West swell at 14 seconds, with the combined energy jumping to 257 – that’s a moderate pulse. The wind is a light cross-onshore, but it’s the biggest swell of the period. The West direction is the optimum for Kiholo Bay, so it’s pointing right at it. Still, for a beach and point setup, that long period might make it a bit straight, but it’s the best chance for a wave.
From Tuesday the 11th through to Thursday the 13th, we’re back to smaller 2-2ft West swells, with energy dropping back down. The wind is mostly cross-onshore. Thursday the 13th afternoon shows a glassy 2ft West swell at 14 seconds, with energy at 104. It’s surfable but ordinary.
The real takeaway is that there’s nothing here for a full-on session. The best bet is Monday the 10th of August, but even that’s a long way off and not a guarantee. We’ve got a long gap of poor surf right at the start, so don’t hold your breath. For now, the kite crew might have a better time with the light winds and little bumps, but for a surfer, it’s a tough stretch.
Stay patient, and keep an eye on the charts.
Rusty.

Information about the Kiholo Bay Surf forecast
The above surf forecast table for Kiholo Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kiholo Bay can be found by selecting the local surf guide option on the grey menu. Our Kiholo Bay 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 (Kiholo Bay) 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 Kiholo Bay 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.
Kiholo Bay is 89 km (55 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.
