The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for our little corner.
Right off the bat, I gotta be straight with you – this is a tough run to call. The whole 16-day window is looking pretty bleak for decent waves, and there’s a big empty stretch at the start. From now through the 18th, the swell is there, but it’s all short-period, wind-affected junk. The water temp is about average for this time of year, nothing wild there.
We get the first faint glimmer of hope on the morning of Wednesday the 19th. Nomozaki picks up a tiny 2 ft swell from the SSW with a light period of 8 seconds, but the magic is in the wind – a glassy offshore from the NE. The combined wave energy is barely a whisper (41). It’s a rare break anyway, so even getting a few clean little runners on the reef would be a treat, but you won’t need anything bigger than a foamie.
After that, it’s a long, flat slog. The swell just keeps dropping into nothingness through the rest of August. There are a few clean days here and there, like the 20th with strong offshore wind, but with waves at 0.7 ft, it’s a lake. Not even worth paddling out for. We see a slight bump in combined energy on the 23rd (up to 71), but it’s all cross-shore wind and poor quality.
The only real looker in the whole forecast is the very last one. On Monday morning, August 31st, we get a glassy morning with a 1 ft, 12-second groundswell from the SW. That’s the longest period we’ve seen all forecast, and the conditions are dead flat calm. The combined energy is a modest 57, so it’s not powerful, but for a spot that rarely breaks, that’s a total window of opportunity. That’s the standout. It’s a long way out, so keep a loose eye on it, but it’s the only thing that screams "go for a dawny."
Honestly, the rest of the run is a write-off. The consistency across the board is miserable, so a blank period like this is just normal for the area. Don’t bin your boards, but maybe pick up a kite if you’re dead set on getting wet in the otherbies.
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.
