The Lowdown
Right, let’s have a look at what we’ve got for the coming stretch.
Well, I’m not gonna sugarcoat it – it’s a slow start here at Nomozaki. This is a beach and reef set-up that rarely breaks, so we’re not dealing with a place that fires every day. The first week is pretty grim, with hardly any surf to speak of and a lot of small, weak, and messy conditions. We’re looking at a solid gap with no real recommendations until Saturday the 22nd of August.
That Saturday morning is where things finally show a pulse. The swell is a modest 3ft from the SSW, period is a short 9 seconds, but the combined energy is a moderate 111. The wind is glassy, which is a huge positive, so it’ll be clean. That said, the waves are surfable but ordinary – don’t expect anything special.
The real standout, the one to circle on the calendar, is Sunday the 23rd of August. Early morning is looking proper glassy with a calm wind, and the swell bumps up to a clean 5ft from the SSW with a 9-second period. The combined energy jumps to 314 (moderate), and the wave comment says it’s good. This is the best on offer in the entire run. For a spot that rarely breaks, this is a moment to get amongst it. The water temp is around 84°, which is about average for this time of year.
Monday the 24th still has some pulse, with a glassy 4ft SSW swell and 246 energy, but it’s not as good as the day before.
After that, the energy drops off again into tiny, weak surf, and then we get a weird shift into the end of August and start of September. There’s a lot of long-period groundswell (15-17 seconds) that pushes the swell height up to 5ft and even 7ft by the 1st and 2nd of September. The combined energy gets seriously strong (over 1000). But here’s the kicker – the wind is howling from the NNE at 22-28 mph for most of it, making it cross-off or offshore but blowing a gale. That’s clean but way too windy for a good surf. The swell is too big for beginners at over 5ft, and with the wind, it’s only really interesting for the experts. The morning of Wednesday the 2nd of September is the pick of that late period – a light cross-off breeze, 7ft SSW groundswell, and excellent conditions for experienced surfers. But it’s a long way off, so don’t get too attached.
Honestly, if you want a surf, your best bet is that Sunday morning on the 23rd. The rest is either flat, messy, or blown out. For a spot that rarely breaks, when it does line up, it’s worth it. Keep an eye on that Wednesday the 2nd, but treat it as a hopeful maybe.
Stay keen.

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.
