The Lowdown
G’day, it’s Rusty here. Let’s be straight with you—the next couple of weeks are looking pretty grim for a paddle. We’ve got a long stretch of small, weak, and messy surf ahead, so if you’re hanging for a wave, you’re going to need some patience. The water’s sitting at 84°F, which is about average for this time of year, so at least it’ll be warm while you’re sitting there wondering where the swell went.
Looking at Nomozaki (Nagasaki), the first real highlight doesn’t even pop up until Saturday the 29th of August, which is over a week away. Before that, it’s a whole lot of nothing. From the 14th right through to the 28th, we’re dealing with tiny swell—mostly below 3ft—and a lot of it is short-period slop. The energy is weak too, often in the single digits or low double digits, like on the 20th when it’s only 18. There are a few cleaner moments, like the 19th and 22nd with a light offshore breeze, but the waves are just too small to get excited about. You’d be fighting for ankle-biters.
Then, on the morning of Saturday the 29th, things finally wake up. We’ve got a 7ft SSW swell with a 7-second period, and the energy jumps right up to 440, which is strong. The wind is light offshore from the NNE, keeping it clean. This is the standout of the whole window. It’s a beach and reef setup, and it’s a rare break, so it’s a bit special when it lines up. It’s pushing 7ft though, so it’s getting a bit serious for beginners—this one’s for those of you with some experience. The afternoon still has decent size at 6ft, but the wind picks up and goes cross-off from the N, making it a bit more average.
So, if you can wait it out, that Saturday morning is your shot. It’s promising, but it’s a long-range call, so don’t book your flights yet. Before that, it’s a waiting game. The crowds at Nomozaki can be around sometimes, and when it’s good, it’ll be worth it. But for now, keep the board in the car and the coffee hot.
Later, Rusty.

Information about the Nomozaki Surf forecast
The above surf forecast table for Nomozaki provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Nomozaki can be found by selecting the local surf guide option on the grey menu. Our Nomozaki 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 (Nomozaki) 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 Nomozaki 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.
Nomozaki is 14 km (9 miles) from Togitsu. If you plan a holiday in Kyu Shu, look for hotels and other accommodation in Togitsu. Togitsu has rooms for a wide range of budgets as well as car hire and transport links.
