The Lowdown
Alright, let’s get real about what’s on the cards for our stretch of coast.
We’re looking at a pretty flat and frustrating start to this run. The surf for the first few days is barely a pulse, and the wind is mostly cross-onshore or onshore. Honestly, it’s not worth paddling out for. We’ve got a shot at Golfcourse, but through Tuesday the 20th, conditions are just poor. There’s a tiny bit of energy on Thursday the 21st, but it’s still marginal at best, and the wind keeps messing with the surface. You’d be fighting it the whole time.
The water temp is sitting at 83°F, which is right about normal for this time of year, so at least it’ll be warm while you’re getting skunked.
Now, here’s where things get interesting. There’s a real pulse of long-period groundswell arriving around Monday the 24th. The energy jumps up into the moderate zone (459) and it’s coming from the ESE with a period of 14-16 seconds. That’s a proper groundswell. The morning of the 24th looks like it might just be surfable, but the winds are still cross-onshore, so it’ll be a bit bumpy.
The real story, though, is the big one. By Tuesday the 25th, that swell really kicks in. We’re looking at 8ft to 8ft waves with a huge jump in energy (3214 to 3682). This is a powerful swell, but it’s still a bit rough with the cross-onshore wind. The wave period is long, 16-17 seconds, which is fantastic for shape, but it’s also a lot of water moving around. Wednesday the 26th sees it get bigger, up to 10ft to 12ft. The energy is now strong (5117 to 6781). This is when it gets serious.
The problem is, this spot—Golfcourse—is a beginner spot. Once the swell pushes much past 5ft, it’s too much for beginners, and over 8ft, it’s strictly for experts. So Wednesday through Friday the 28th is going to be a washout for the average surfer. The conditions are clean, with offshore winds on Friday morning, but the size is just overwhelming. It would be one for the big-wave chargers only, and even then, it’s a close-out risk at a beach break.
Then we get the standout. Saturday morning, the 29th of August. The swell drops back to 7ft, the period is still a solid 13 seconds from the SE, and the wind goes glassy. The energy is still strong (2014), but it’s manageable. The conditions are described as glassy, and this is the one window where everything lines up. It’s still big, but for an experienced surfer, this is the pick of the whole 16-day forecast. It’s going to be powerful and hollow, but that glassy wind will keep it clean. This is what you wait for.
After that, the swell backs off a touch but stays solid into Sunday the 30th and Monday the 31st, though the winds get more cross-onshore again. The size is still challenging, but the quality drops off. Into the first week of September, we’ve got more solid swell, but the winds are choppier. It stays in the 7ft to 10ft range, but the surface is going to be messy.
So, if you’re an experienced surfer, that Saturday morning the 29th is your window. It’s going to be powerful, but with that glassy wind, it’ll be the cleanest big day you’ll get. For everyone else, the next week and a half is either too small, too messy, or way too big. Keep an eye on it, though. With this much energy in the water, it won't stay flat for long.

Information about the Golfcourse Surf forecast
The above surf forecast table for Golfcourse provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Golfcourse can be found by selecting the local surf guide option on the grey menu. Our Golfcourse 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 (Golfcourse) 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 Golfcourse 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.
Golfcourse is 6 km (4 miles) from Miyazaki-shi. If you plan a holiday in Kyu Shu, look for hotels and other accommodation in Miyazaki-shi. Miyazaki-shi has rooms for a wide range of budgets as well as car hire and transport links.
