The Lowdown
Hey, Rusty here. Let’s talk surf for Nomozaki – it’s been a bit flat, but there are a couple of windows to keep an eye on.
The next week or so is pretty grim. From now right through to late August, the swell is either non-existent or the conditions are junk. You’re looking at a long, quiet stretch with nothing really surfable. It’s a poor run, which is just how it goes sometimes in this region.
The first flicker of hope is on Saturday, August 29th. The morning is still flat, but by Saturday afternoon the wind turns glassy – a light easterly breeze – and a clean little swell shows up. It’s a Southerly groundswell with a very long period of 14 seconds, pushing in around 3ft. The combined energy reading is 320, which shows there’s some real push behind it. That long period will give the waves some shape, but at this beach-and-reef setup, those sets might stand up a bit quick. Great for a clean, fun session.
Then we get a bigger pulse on Sunday, August 30th morning. Swell size bumps up to 6-7ft from the SSW, but the period is short at 7 seconds – more of a windswell. The wind is light offshore from the ENE, keeping it clean. The combined energy is 627, so there’s some serious grunt. That 6-7ft is big for this spot, and with the short period, it’ll be dumping and challenging. That’s expert territory only. If you’re skilled and want some heavy waves, that Sunday morning window is your main target, but it’s a long way out so don’t get too attached.
Water temp is around 84° – about average for the season, so boardies and a rash guard will do.
After that Sunday morning, it flattens right off again heading into September. Tiny, weak leftovers.
Bottom line: you’ve got a flat spell now, then Saturday afternoon the 29th for clean, long-period waves in the 3ft range, and Sunday morning the 30th for a short but punchy 6-7ft session for the experienced crew. Then it’s back to flatness.
Stay tuned.
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.
