The Lowdown
Alright, let’s get straight into it.
First up, the bad news: Inamura Point is pretty much flat for over a week. From now through to Thursday the 18th, we’re looking at tiny, weak surf – nothing over 3ft and most of it below 2ft. Winds are mostly cross-off or onshore, and the energy is basically non-existent, with combined swell energy barely getting into double digits (like 10 or 20). There’s just nothing to ride. You’d be wasting your time.
Then we hit Friday the 19th of September, and things finally wake up. A proper south-east groundswell arrives, pushing 6ft on the Saturday morning with a very long period of 16 seconds. This is serious energy – the combined swell energy jumps to 1412, which is strong. Winds are fresh offshore from the north all day, which is a massive positive for a reef break like Inamura Point. The swell direction is south-east, and with the optimum swell direction being from the south, that’s a good match. This is easily the standout of the whole outlook: Saturday the 19th, Inamura Point, with 6–6ft of clean, offshore-groomed surf.
Be aware this is an advanced reef break, and with over 5ft, it’s not for beginners. The long period means the waves will have real punch and bigger gaps between sets, making it easier to get out the back. Crowds are often a factor here, so expect company.
Sunday the 20th still holds decent 5ft swell, but the period drops to 11 seconds and the wind remains offshore. Still good, but not quite the peak of Saturday.
That Monday the 21st sees another pulse, with 6–7ft of south-south-west groundswell arriving, period 13 seconds. But the wind goes light cross-shore to onshore, so the surface won’t be as clean. Still, over 7ft is expert territory.
After Tuesday the 22nd, the swell fades fast, and by the 23rd we’re back to tiny junk with a severe gale warning – definitely not for paddling, more for kiting if you’re into that.
The very end of the outlook, Monday the 28th of September, shows a tease of 2ft swell with a 17-second period and offshore wind. The combined energy is 306 (moderate), but it’s just too small to get excited about. That’s a maybe for a longboard.
So, to sum it up: Inamura Point on Saturday the 19th of September is your best bet. Clean, strong offshore winds, solid 6–6ft of long-period south-east groundswell. Mark it in your calendar.
Keep an eye on the water temp. It’s about average for the time of year, no major anomaly. No extra warmth or chill to report.
This is Rusty, signing off.

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.
