The Lowdown

Alright, let me level with you about the next couple of weeks here. It's looking pretty grim, to be honest.

The week starts with a tiny bit of weak energy, but it's not really worth getting wet for. On Thursday morning, we've got a small, long-period groundswell from the west pushing about 3ft. The period is a solid 15 seconds, so there's a bit of pull in the water, but the combined energy is only 275 (weak). The wind is a light cross-onshore, so it's a bit bumpy. Water temp is around 80°, which is about 1° warmer than average for this time of year – nothing dramatic, just a touch warmer than usual.

By Friday morning, the swell drops to 2ft, and the wind turns more onshore, making it a real struggle. The energy drops to 203 (weak). The afternoon glass off is nice, but the swell is only 2ft. You could catch a few, but you'd be scratching for them.

The weekend is a total write-off. Saturday and Sunday the swell fades away to nothing, with energy numbers of 97 and 55. It's just poor conditions. Then we hit a massive dead zone. From Monday, July 21st, all the way through to the morning of the 30th, there's zero swell. Absolutely nothing. For a spot like this, it's not abnormal to have a flat spell, but it's frustrating.

There's a tiny flicker on the 28th, with a 1ft glassy afternoon, but it's a 3-second windswell with an energy of just 2. That's not waves, that's a ripple.

The only thing that even looks like a pulse is on the morning of July 29th. A small 2ft north swell shows up, with a period of 8 seconds, and the energy climbs to 68 (still weak). The wind is onshore, so it's going to be choppy. It's not a standout, just a tiny blip in a very flat forecast.

So, the honest truth is, there's nothing worth paddling for in this 16-day window. It's a long stretch of flat, small, or messy conditions. Sometimes the ocean just shuts down. We'll have to wait and see if the next forecast brings anything better.

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.
