Alright, Rusty here again, giving it to you in feet and Fahrenheit.
The water here is sitting at about 81°, which is a touch warmer than normal for the time of year – feels nice.
The next week and a half is pretty bleak, honestly. From now until the morning of Sunday, July 12th, there’s no surf worth talking about. It’s flat, tiny, or blown out. The first time you might even consider getting wet is Sunday the 12th afternoon. That gives you a tiny 1ft swell from the SW, period at 16 seconds, with moderate wave energy (117). The wind goes glassy calm, so it’ll be clean, but the waves are very small and ordinary.
The best of a bad run shows up around Tuesday the 14th and peaks on Wednesday the 15th and Thursday the 16th. Swell height creeps up to about 2ft from the W, with periods of 15-16 seconds, and combined energy in the 220-248 range – moderate. The wind is usually a light cross-onshore or cross-shore, keeping the surface a bit messed up. The cleanest window in that stretch may be the afternoon of Friday the 17th – still small at about 2ft from the W, period 14 seconds, but the wind goes glassy, giving you clean little waves with 168 energy. Not epic, but the best of the lot.
After that, the swell fades back to 1-2ft through the rest of the second week, with only a few glassy moments.
For the break: Kua Bay (Hawaii) is your only call. It’s fairly consistent, open to WNW swell, and the optimum direction is right in that zone. With swell staying under 3ft, it’s fine for intermediates and beginners won’t be in over their heads. Crowds are sometimes an issue, so expect some company on the clean afternoons. The long-period swell (16-17 seconds) means longer waits between sets, making the paddle out easier, but the small size and mostly light onshore wind keep the quality just average.
Bottom line: a few glassy afternoons are your only real chance. If you’re a kiter, the wind is mostly too light to be exciting. Surf’s not great right now.
Rusty, signing off.

Information about the Kua Bay Surf forecast
The above surf forecast table for Kua Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kua Bay can be found by selecting the local surf guide option on the grey menu. Our Kua 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 (Kua 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 Kua 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.
Kua Bay is 97 km (60 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.
