The Lowdown
Alright, let's get into it. This is Rusty, and I'm looking at what's on the table for Nomozaki over the next couple of weeks. I gotta be straight with you – it's a tough stretch. We're looking at a long, dry spell with nothing really worth paddling out for.
The first hint of anything that might be surfable doesn't show up until Saturday, the 22nd of August. The morning will see a small 3ft swell from the SSW, with a period of 9 seconds. The wind will be light and variable, so it might be clean, but the combined energy is only moderate (121). It's a real "maybe" session. The afternoon picks up a bit more size, pushing 5ft from the same direction, and the energy jumps up (294), but the wind swings onshore, making it choppy and messy. It's a marginal call at best.
Sunday the 23rd and Monday the 24th are pretty much write-offs. The swell hangs around 3ft to 5ft, but those winds are strong and cross-onshore, creating lumpy, choppy conditions. Not worth getting wet for.
After that, it drops right off again. From Tuesday the 25th all the way through to Saturday the 30th, we're looking at tiny, insignificant waves – mostly under 2ft. There's a lot of glassy mornings and clean conditions, but with no swell to push, it's a flat spell.
Now, hold on to your board. The one true standout in this whole forecast is Sunday, the 30th of August. The morning brings a serious pulse of swell from the S, hitting 12ft. That's a big number, folks. The combined energy is a massive 1920, so there's a lot of power in the water. The wind is offshore from the NE, around 9 mph, blowing clean. This is a day for experienced surfers only. The period is 9 seconds, so it's more of a wind swell, but with that size and offshore wind, Nomozaki's beach-and-reef setup could be firing. The afternoon drops to 8ft, still offshore, and still very good, but the morning is the real window. Keep in mind, this is a long-range call, so it's promising but not set in stone.
The water temperature is sitting around 84°, which is pretty normal for this time of year.
So, to sum it up: a quiet period with a few small, marginal windows, but the big one is the 30th of August. Mark your calendar for that Sunday morning, but only if you know what you're doing.

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.
