The Lowdown
G’day, I’m Rusty, and I’ve been staring at the charts for Nomozaki (Nagasaki) all morning, trying to find some hope. Honestly, the next couple of weeks look pretty drawn out, with a lot of small, ordinary days and only one proper window that’s got me a bit excited.
Right now, we’re coming off a flat spell. Friday the 21st and Saturday the 22nd are flat to tiny – we’re talking knee-high dribble at best, with a 1ft to 3ft SSW swell and combined wave energy sitting at a very weak 19 to 102. The water is a warm 83°F, which is about average for this time of year, but with these tiny waves, it’s not making a difference.
Sunday the 23rd and Monday the 24th stay small, around 3ft from the SSW with 10-second periods. Mornings are glassy, but the afternoons get chopped up by a cross-onshore or cross-shore breeze. Surfable, sure, but nothing to write home about.
The real hope shows up late in the week. Thursday the 27th is where things start to turn. We get a 5ft SSW groundswell (10-second periods) pushing in under light offshore NE winds in the morning. The combined energy jumps to 392 – moderate energy – and it’ll be clean. This is the first time the wave comment says “expect good surf conditions.” Still, it’s not huge, so beginners can handle it.
Then, the standout of the whole outlook is Friday the 28th and Saturday the 29th. Friday morning serves up a 5ft SSW swell, period 11 seconds, light offshore NE breeze, and a combined energy of 517. Saturday morning is the pick: 6ft SSW swell, 12-second period, glassy conditions with ENE light air, and combined energy hitting 753 – that’s solid moderate energy pushing through. That Saturday morning session at Nomozaki is going to be clean, with proper shape from that longer-period groundswell. The break is a beach-and-reef setup, so that long-period swell should wrap in nicely. It’s almost too big for beginners, but for anyone else, it’s the best on offer. The afternoon on Saturday gets messy with a cross-shore breeze again.
After that, we drop back into tiny, poor surf from Sunday the 30th right through to the end of the first week of September. There’s a gap of about six days where nothing really works – swells are under 2ft, periods are short or inconsistent, and the winds are all over the place. The combined energy numbers drop into the double digits, so you’re best off doing something else.
For the long-range, the 3rd and 4th of September have some 1ft to 2ft SSW swells with offshore NE winds, but the energy is weak (31 to 108). Not worth the paddle unless you’re desperate for a longboard.
Overall, your best bet is clear: Saturday morning, August 29th at Nomozaki. 6ft, 12-second SSW groundswell, glassy, clean, moderate energy. That’s the one. Enjoy it while it lasts.

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.
