The Lowdown
G’day, Rusty here. Let’s be straight with you: the next couple of weeks are a real mixed bag, and for the most part, we’re looking at a whole lot of flatness before things finally wake up. The first week is honestly a write-off for any proper surfing, but there’s a light at the end of the tunnel—around the 19th and 20th, this place is going to turn on. Hang in there, because the wait is worth it.
Right now, and for the next several days, it’s flat and frustrating. We’re talkin’ tiny ankle-slopers with not enough energy to push a sea-lion off a sandbar. The swell energy is in the single digits to low 20s – really weak stuff. Wind is all over the shop, but there’s nothing for it to blow on anyway. You’d be wasting your time paddling out for waves that are barely breaking. This period of nothing stretches from now through to about the 18th. It’s bleak, but it’s one of those things – it ain’t gonna last forever.
Now, let’s get to the good stuff. The first real standout is the Sunday morning of the 20th at Inamura Point. This is the pick of the whole outlook. We’ve got a solid 7ft of south swell, with a 15-second period – that’s proper groundswell, and it’s got some serious push behind it. The combined energy is reading 2088, which is strong, and we’re looking at glassy conditions. Dead calm. Zero wind. That’s about as clean as it gets. This is for experienced surfers, no doubt – 7ft with that period is serious. But if you’re confident in your abilities, this is the session you wait for. The south swell direction is ideal for this spot, and with no wind, it’s going to be an absolute beauty. The crowds are often around, so you might have to work for your waves, but it’ll be worth it.
The Saturday afternoon of the 19th is also worth a serious look. We’ve got 7ft of SSE swell, period around 15 seconds, with a combined energy of 3396 – that’s a big jump in power. There’s a light cross-offshore breeze from the NE, which should keep the face reasonably clean. It’s another expert-only day, especially with that size coming from a similar direction. It’s not quite as perfect as the Sunday morning, but it’s a very close second.
Earlier on the Saturday morning of the 19th, you’ve got 7ft at 16 seconds – a touch longer period and plenty of energy (1928). It’s clean again with a cross-offshore wind. It’s all good, but the afternoon looks like it has that little extra juice. Also, that Sunday the 21st morning is a weird one – the models are predicting a monster 23ft swell with a 15-second period. That’s a massive amount of energy (20493), but it’s just too big for this break. Even if the wind is glassy, that’s a danger zone, not a surf zone. Leave that one well alone. The Monday afternoon of the 21st is more manageable at 12ft, but that’s still solidly in the expert-only realm and the quality drops off a bit compared to the Sunday.
After that, it fades fast. The last week of the outlook gets back to small and junky, with onshore winds and weak energy. There’s a bit of a pulse around the 24th but it’s blown out and messy with strong winds, so it’s a skip.
So, to wrap it up: the first week and a half is a dustbowl. Don’t even bother. Mark your calendar for the 19th and 20th – that’s your window. The morning of the 20th is the absolute standout, with the afternoon of the 19th a close second. Go get some.

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.
