G'day, Rusty here. Been staring at the charts for Kiholo Bay, and to be honest, it's a quiet stretch ahead. Don't get your hopes up for any pumping sessions right now—the next week and a half is mostly flat or tiny, with only a slight pulse of energy trying to show itself later on. The water temp is running a touch warmer than normal for this time of year, sitting around 81°.

The first solid hint of something to ride doesn't show up until Monday afternoon, July 14th. That's a long wait. Before that, we're looking at days of near-flat conditions with cross-onshore breezes making it even less inviting. A few glassy moments pop up here and there, but with nothing underneath them, it's just a pretty ocean.

Now, the standout window—and I mean the only one worth paddling out for—is Tuesday afternoon, July 14th, through to Thursday afternoon, July 16th. On Tuesday afternoon, we finally see a bit of push: a 3ft W swell at a very generous 17-second period, and the combined energy hits 454—moderate wave energy at last. The wind goes glassy, so it'll be clean. That's the pick. A long-period groundswell like that will wrap nicely into the bay, and with that light offshore wind, it'll be worth the wait. Wednesday afternoon the 15th offers a similar setup: 3ft of WNW swell at 16 seconds, combined energy of 447, and glassy winds again. Both those afternoons are your best bets for a few clean, fun waves.

Those early morning sessions on the 14th and 15th? The wind is onshore and a little stronger, so the waves won't be as tidy. Thursday afternoon the 16th also has some potential with a 3ft W swell and glassy conditions, but the rain showers could put a bit of lump on the surface.

Overall, it’s a long dry spell until that mid-July window. The swell direction is coming from the west and west-northwest, which is in line with what the spot likes (optimum being WNW). It's a consistent break when there's swell, but it rarely sees much, so this little run is notable. Crowds can pop up here sometimes, especially when a clean 3ft wave shows up.

There's nothing for beginners here in that window, the waves are small enough to be forgiving, but not the best for learning. Experts might find the long period a bit tricky for the beach section, but the point and reef will handle it well.

So, keep an eye on that Tuesday through Thursday window in the second week. It's not a world-class swell, but after all that flatness, it'll feel like a gift.

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.
