The Lowdown
Alright, Rusty here, checkin’ the charts for Nomozaki. Gotta be honest, the next couple of weeks are pretty slim pickins. The water’s sitting at 84°F, just a touch above the average for this time of year, so it’s nice and warm.
The first real chance of any surf doesn’t show up until the very end of the outlook. The first 15 days are mostly tiny, weak, and choppy. Swell energy is almost always in the low double or single digits, which is weak. There’s a bump on the 22nd and 23rd of August, with swell hitting 5ft to 7ft from the SSW – that’s more size, but the wind is fresh onshore, making it lumpy and messy. The energy climbs to moderate, but it’s poor quality. That stretch would be more interesting for kite surfing than paddle surfing.
The only standout in this whole 16-day window is the very end. On the 1st of September, we’ve got a South swell with a very long period of 16 seconds, bringing 4ft of swell. The combined energy hits 634, which is strong. Best of all, the wind goes glassy in the morning and light offshore through the afternoon. That’s groundswell, and that long period works best at a reef or point setup, but Nomozaki is a beach and reef mix, so it could still offer some clean lines. The crowd factor is “sometimes,” so you might have company, but for the first decent window in weeks, it’s the best bet. Just keep in mind, this is a long-range call, so it’s promising but not locked in yet.
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.
