The Lowdown

Alright, let’s have a look at what’s on the table for Kiholo Bay. I’ve got to be straight with you – this is one of those quiet stretches where the ocean just isn’t cooperating. The whole 16-day window is a flat spell, with no real surf to get excited about. We’ve got a long gap from now all the way through, with nothing but tiny, weak signals showing up right at the very tail end.

Right now, through Wednesday 22 July and into the weekend, there’s zero wave energy. The combined energy reads 0 (0) – that’s a dead flat ocean. The water temp is sitting at 80°, which is about what you’d expect for this time of year, nothing unusual there. The wind does swing glassy at times, especially in the afternoons, but without any swell, it’s just a pretty, flat lake.

We finally see a tiny pulse arrive on Thursday 30 July afternoon. A south-west swell of 1 foot, but with a very long period of 18 seconds – that’s a groundswell, but it’s so small it won’t do much. The combined energy is only 49 (49), still weak. Winds are light cross-onshore from the north-west, not ideal. The wave comment says “poor surf conditions,” and I’m not going to argue with that.

This pattern continues into the first week of August. From Friday 31 July through to the end of the window on Thursday 6 August, we see the same story: swell heights of just 0.7 to 1 feet, mostly from the west or west-northwest, with periods between 12 and 16 seconds. The combined energy stays in the 14 to 91 range – all weak. A few windows show glassy conditions, like on the afternoon of Sunday 2 August and again on the afternoon of Wednesday 5 August, but with barely a ripple of swell, it’s still not worth paddling out for.

The best of a bad bunch? Honestly, nothing stands out. The swell is too small, and the direction – west and west-northwest – isn’t ideal for Kiholo Bay, which wants a good WNW swell for its optimum. The waves that do show are better suited for a point break or reef, and Kiholo is a beach and point setup, so the long-period groundswell might break a bit too straight across the beach.

There’s no surf for beginners or experts here – the biggest swell is 1 feet, well under the 5-foot mark. The whole thing is a bust. These blank runs happen in this area, and it’s just one of those quiet spells. Forecasts can change, but right now, I’d leave the board at home.

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.
