The Lowdown
Alright, this is Rusty. Let's have a look at what's on the cards for the South Coast.
Honestly, the next week and a half is a real bummer. We’ve got a whole lot of nothing going on at Inamura Point. From Friday the 21st all the way through to the afternoon of the 29th, the wave quality is just plain poor. The wind is mostly onshore or cross-onshore, and the swell is either tiny or blown out. It’s a real stretch of flat, lumpy, or choppy conditions. There’s a bit of a tease on the morning of Monday the 24th when a long-period groundswell rolls in at 4ft from the SSE, but the onshore wind kills it. The combined energy jumps to 1051 (moderate wave energy), but it’s a frustrating "coulda been" scenario.
We finally get a break in the gloom on the morning of Sunday the 30th. The wind clocks around to a nice gentle offshore from the NNE, cleaning things up. The swell is small, 2.5ft from the SSE, and the period is a solid 12 seconds (groundswell). The energy is weak at 196, but after so much junk, clean, surfable waves are a welcome sight. It’s nothing special, but it’s a paddle.
Now, the real story here is the big swell that’s brewing for the first week of September. The standout is the morning of Thursday the 4th of September. This is the one to circle on the calendar. We’re looking at a massive 18ft swell from the SSE, with a period of 11 seconds. The combined energy is a staggering 7470 (very strong wave energy). The wind is howling out of the north at 30 km/h, which is a fresh offshore, meaning the waves will be holding up and clean. This is a serious, heavy, expert-only wave. That size is way too big for beginners and only for the experienced crew. The 11-second period is a bit short for a groundswell of that size, which could make it a little crumbly, but the sheer power is undeniable. The afternoon of the 3rd of September is also a solid option, with a 12ft swell from the SE and a clean cross-offshore breeze, but Thursday morning is the true peak.
This is a spot that’s exposed to the south swell, so the direction is a perfect match. It’s a reef break, so it can handle the long-period swell well, but with that much energy, you need to know what you’re doing. Crowds are likely here, so get there early.
So, the long and short of it: a terrible first week and a half, then a glimmer of clean small waves, finishing with a monster swell that’s the real deal. Stay patient.

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.
