The Lowdown

Alright, let’s get into it. The next couple of weeks are a bit of a slow burn for us here, but there’s a definite pulse of energy coming through if you’re patient.

We’re looking at a long stretch of small, weak surf for the first few days. Wednesday and Thursday are pretty much flat, just tiny leftovers with the water temp sitting at 84°, which is a touch warmer than usual for this time of year. It’s glassy in the mornings, but there’s just nothing to ride.

Friday and Saturday see a slight bump, but it’s still below 1 yard. The wind is offshore and clean, which is nice, but the swell energy is weak, sitting in the 50-190 range. It’s not going to be worth paddling out for unless you’re on a longboard and just want to enjoy the water.

Now, here’s where it gets interesting. The real swell shows up on Sunday the 9th. The energy jumps way up to 3847, with a solid 10ft of SSW swell. This is a big one, but it’s also a bit of a beast. The period is 16 seconds, which is a proper groundswell. For a spot like Nomozaki (Nagasaki), which is a beach and reef setup, this size is going to be heavy and powerful. It’s only for experienced surfers, and the wind is going to be a cross-off, keeping it reasonably clean but with a lot of water moving. This continues into Monday, with even bigger surf, up to 12ft, and the energy is maxed out around 4800. This is expert territory only. The paddle out will be a mission.

By Tuesday the 11th, it starts to drop a bit, but we’re still looking at 8ft surf. It’s still a solid size, but the period drops to 13 seconds, which makes it a bit more manageable, though still a heavy session. The wind is still cross-off, so it’s going to be a battle out there.

The middle of the week, Wednesday the 12th, things start to settle. The swell drops to 5ft, and the energy drops to 543. It’s cleaner, but the wind turns a bit cross in the afternoon. Morning looks better. This is when it starts to get more fun for the average surfer.

Thursday the 13th and Friday the 14th see a continued drop, with surf around 4ft and then 3ft. The mornings are clean with light offshore winds, making for some decent, if not spectacular, longboard waves. The energy is in the 130-300 range, so it’s weak to moderate.

The weekend of the 15th and 16th is small again, with waves around 2ft. It’s not really worth a dedicated session unless you’re desperate.

The last few days of the forecast period, from the 17th to the 20th, are pretty flat again. The swell drops back down to 1ft, and the energy is negligible. It’s a definite flat spell.

So, the standout window is clearly Sunday and Monday, the 9th and 10th. That’s the big, powerful SSW groundswell. It’s not for the faint of heart, but for the experts out there, that’s the one to circle. The other slightly more accessible window is Wednesday the 12th and Thursday the 13th, when the swell is still decent but the size is a bit more forgiving.

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.
