The Lowdown
Alright, let’s get into it. For the next 16 days, the surf outlook is a real mixed bag, and honestly, for the first week, it’s gonna be a struggle. We’re kicking off with a long, quiet stretch, but there’s a glimmer of something special toward the end if you can wait it out.
The immediate future is grim. From Wednesday, July 29th, right through to the end of the first week in August, it’s dead flat. Tiny, weak swells barely reaching 1 foot with almost no energy in the water (combined swell energy as low as 11). Winds are light and glassy at times, but there’s just nothing to ride. This is a major gap of about 10 days with no real surf on offer. You’re looking at a long, dry spell.
Then, the second week flips the script completely. A massive storm swell arrives on Friday, August 7th, with a towering 23-foot swell from the NW, but it comes with storm-force cross-shore winds (59-68 mph) and a combined energy reading of 12,980. That is not for paddling. That’s survival conditions, and for a reef break like Corners (Big Island), it’s a write-off. The swell builds further on Saturday, August 8th, hitting a monstrous 28 feet from the SSW with a very long period of 15 seconds. The energy is astronomical at 32,010. The file says it’s too big for this break, and I agree. That’s for experts only, and even then, it’s a mission.
The real standout, the one you want to circle on your calendar, is Tuesday, August 11th. Corners (Big Island) will be firing. We’re looking at a clean 5-foot swell from the SW, with a solid 11-second period and moderate offshore winds from the East at 12 mph. The water temperature is sitting at 86°, which is about 2° warmer than normal for this time of year, so it’s a little extra warm. The combined energy is a moderate 1,290, which is proper for a reef break. The file says it’s excellent for experienced surfers, and I’d call that the best on offer. The wind is offshore, it’s clean, and the swell direction is a perfect match for the optimum. This is the one. After that, Wednesday and Thursday, August 12th and 13th, still offer decent clean waves with 4 feet to 3 feet, gentle offshore winds, and good energy, but the quality drops off a little. Crowds are often at Corners, so expect company.

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