The Lowdown
Alright, listen up. It’s Rusty here, looking at the charts for our stretch of coast. It’s gonna be a slow burner for a while, so don’t rush to wax up just yet.
The next week to ten days are looking pretty grim, to be honest. The swell is tiny and the wind’s all over the place. You’ll be scratching your head wondering if the ocean forgot how to work. There will be some knee-high slop and closeouts, but nothing worth getting wet for. This is a real test of patience.
Then things start to get interesting. As we get into the start of September, the energy starts to build. There’s a pulse of southerly groundswell due on Wednesday the 2nd of September that looks like it packs a punch, but the onshore wind is going to ruin it. It’ll be a messy, blown-out mess, not the kind of thing you want to paddle into unless you enjoy getting smashed on the head. That’s a write-off for the surfer, but for the kitesurfers out there, that’s looking like more your scene.
The back half of that week sees the swell ease but the conditions stay poor. It’s not until the following week, on Monday the 7th of September, that things line up properly. That's the standout. The map is all pointing at Inamura Point (Big Island) . The swell is showing a solid 6 ft from the south with a long period of 14 seconds. That’s proper groundswell energy, and the combined energy is strong, reading 1369 in the model. The wind is light and from the northeast, keeping it glassy and clean. This is a heavy, powerful reef wave though, so it’s for the experienced crew only. It’s going to be thick and challenging, but if you’re confident, it will be worth the paddle out. Crowds are likely here, but on a day like this, everyone will be frothing.
The next day, Tuesday the 8th of September, looks like the pick of the whole run. It’s still got that S swell at 6 ft and a 12-second period, but the wind goes glassy in the afternoon. It’s still a proper wave, so again, not for the faint of heart, but for the crew that knows the lineup, this will be excellent. The water temp is sitting at 82°, which is about normal for this time of year, so a spring suit is the go-to.
After that, the swell slowly winds down through the week, with a few cleaner but smaller days on the 9th and 10th, but nothing that will really get the heart racing.
So, the long and the short of it is: hold tight. The surf is going to be scarce for the next week. But that window from the 7th to the 9th of September looks seriously promising. It's a long way out, so the forecast isn't locked in, but it's got all the ingredients. Mark it on the calendar.
Be patient, check the buoys (well, don't actually), and I'll see you in the water when it turns on.
Rusty.

Information about the Inamura Point Surf forecast
The above surf forecast table for Inamura Point provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Inamura Point can be found by selecting the local surf guide option on the grey menu. Our Inamura Point 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 (Inamura Point) 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 Inamura Point 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.
Inamura Point is 7 km (4 miles) from the city of Kamakura. If you plan a holiday in Kanagawa, look for hotels and other accommodation in Kamakura. Kamakura has rooms for a wide range of budgets as well as car hire and transport links.
