The Lowdown
Alright, Rusty here. Let’s get into it.
The long-range outlook has a bit of a slow start, but there’s a couple of solid windows on offer. The first real chance for a wave doesn’t show up until Wednesday morning, the 26th of August, and that’s the pick of the early period.
Wednesday morning, the 26th, we’ve got Inamura Point looking clean and inviting. The water’s about average for the time of year, so nothing weird there. The swell is a tidy 3ft from the SSW, with a long 12-second period, which will push in with some real shape and energy for a reef break like this. Combined swell energy is moderate (250). Winds are glassy from the SW. This is your window for clean, lined-up waves. Crowds are possible here, so don’t expect to have it all to yourself.
The wind goes onshore that afternoon, turning it to slop. The next several days through the end of August and into early September are mostly poor, with either onshore winds, tiny swell, or messy conditions. There’s a small window on Tuesday morning, the 1st of September, with a clean 3ft SSW swell and the same moderate energy (250) but with a gentle cross-off breeze. It’s surfable, but nothing to write home about. The period is still a solid 12 seconds, so the waves will have some push.
Then things get interesting. The real standout window is shaping up for the second week. On Monday morning, the 7th of September, Inamura Point wakes up with a glassy 3ft S swell, 11-second period, and moderate energy (259). That’s a nice clean start to the week. But the true highlight is Tuesday the 8th of September. The morning shows a solid 12ft S swell, with a 12-second period and very strong energy (3172). That’s serious, powerful groundswell. The wind is a clean cross-off from the NE, so the face will be clean. This is big – over 8ft, so it’s experts only. The afternoon holds the same size and power (3049), still with clean conditions. If you’ve got the skills, this is the session to aim for. That long period swell will wrap nicely into the reef at Inamura Point.
After that, Wednesday the 9th and Thursday the 10th drop back down, but there’s still decent, clean, cross-off conditions with smaller swell in the 5ft to 7ft range for the more experienced crew.
So, the bottom line: The first real surf is Wednesday morning, August 26th – small but clean. Then a long lull. The absolute standout, and the one to circle on the calendar, is Tuesday, September 8th – big, powerful, and clean. That’s your strike mission.
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.
