The Lowdown
Alright folks, Rusty here. Let’s have a good look at what’s coming up for Nomozaki.
Overall, it’s a pretty flat and quiet start, with a long dry spell. The first week or so is mostly a write-off for any decent surf. We’ve got a long gap from now until the end of the first week with very little to get excited about. Then, out of the blue, we get a massive spike in swell right at the start of the second week. That’s the one to keep an eye on, but it’s for experts only.
We start off with tiny, weak waves. Wednesday the 26th has a 1ft SSW swell with a very long 15 second period, but the combined energy is only 66 – that’s weak. Offshore wind in the morning keeps it clean, but there’s just no power. The next few days are a mix of onshore and cross-shore winds with small, poor quality swell. The energy builds a bit on the 27th and 28th, with a 5ft to 5ft SSW swell, but the winds are messy and the conditions are just marginal at best. The combined energy hits 674 on Friday morning, but it’s still not coming together.
The weekend sees a drop again. Sunday the 30th has a tiny 3ft SW swell, and while the morning is glassy, the energy is only 127, so it’s barely surfable. Monday and Tuesday are even smaller, with clean offshore winds but next to no swell. By Wednesday the 2nd of September, we’re down to 1ft of swell, and the wind is howling. It’s a pretty grim run.
Now, the standout. Friday, the 4th of September is the one. The morning is absolutely pumping with a 21ft SSW swell, a 13 second period, and glassy conditions. The combined energy is a massive 13815 – that’s strong, powerful groundswell. This is exceptional but only for expert surfers. It’s a beach and reef setup here, and with that size and a long period, it’ll be unrideable for anyone but the most experienced. The afternoon is still huge at 18ft, but also glassy. This is the big event of the forecast.
After that, the swell drops quickly. Saturday the 5th has a 7ft SSW swell, but the period drops to 7 seconds, so it’s weak and lumpy. It’s clean with offshore wind, but it’s a far cry from the day before. Then it’s back to tiny, virtually flat surf for the rest of the run into the second week.
So, to sum it up: if you’re an expert, clear your schedule for the morning of Friday the 4th of September. For everyone else, it’s going to be a long wait. The water temperature is about average for the time of year, nothing unusual.
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.
