The Lowdown
Alright, it’s Rusty here. Let’s talk about the surf outlook for Nomozaki, and honestly, I’m a bit bummed to say it’s a pretty flat stretch for the first week or so. We’re looking at a long gap of small, weak energy with no real surf on offer until the very end of the forecast.
The first recommendation doesn’t pop up until about a week and a half from now, so from the 18th of July all the way through the 30th, it’s a long, slow grind. The combined swell energy is sitting in the double digits or low triple digits, mostly weak throughout the early days, with wave heights barely scraping 3 ft and short periods around 7 to 8 seconds. That’s just not enough to get excited about. The water temperature is about average for the time of year, so nothing wild there.
Things start to change on the 31st of July. That morning, we get a little bump with a 1 ft swell from the south, but here’s the kicker: the period jumps to 16 seconds, which is a very long period groundswell. The combined energy is still low but the wind is fresh offshore from the northeast, keeping things clean. This is a faint whisper of something better, but still tiny.
The real standout – and I mean the only one worth paddling out for – shows up on the 1st of August. We’ve got a 2 ft south swell picking up in the morning, with a 17-second period, and combined energy climbing to moderate. It’s clean with a cross-offshore breeze. By the afternoon, the swell bumps to 2 ft from the south, period 16 seconds, and the combined energy gets stronger. That’s still small, but it’s the most energy we’ve seen all forecast. The water is still average temp for the season.
Then on the 2nd of August, Sunday morning, it gets serious. A 10 ft south swell, 15-second period, and combined energy of very strong. That’s a big, powerful groundswell. But the wind is a strong cross-shore from the northwest at 28 mph, creating messy, choppy conditions. For a beach and reef setup like Nomozaki, this is less about clean surfing and more about heavy, combative conditions. This is only for experienced surfers, and honestly, with that wind, it might be more interesting for kite surfing than paddle surfing. It breaks rarely, but when it does, it’s a serious beast.
The 31st of July morning is the best of the small stuff, but the 1st of August afternoon is the one to target if you want a window of clean, moderate-energy waves. The 2nd of August has the size, but it’s a mess.
Rusty out.

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.
