The Lowdown
Alright, grab your board, let's see what’s happening at Inamura Point.
Honestly, the first week or so is pretty flat. We've got a long stretch of tiny, weak waves and onshore wind that’s just not going to give us anything rideable. From the 19th through to the 23rd, it's a bust – we’re looking at knee-high slop at best, with the swell energy barely registering (20-66). The wind is mostly straight onshore, just making a mess of things. You'd be better off doing a lap of the carpark than paddling out.
Now, things start to get interesting around Monday the 24th. A new longer-period swell starts showing up, but the wind is still on it, making it a real struggle. Tuesday the 25th sees the swell jump to 5 ft, with a solid 14-second period and some serious energy behind it (959), but again, onshore wind kills the quality. This pattern continues for a few days – size and power are there, but the wind is just cruel. The morning of Thursday the 27th gets a clean window with cross-offshore wind and a 5 ft south swell, but it’s a short-lived reprieve before the wind swings around again.
The real standout, and I mean the one to circle on your calendar, is Saturday the 29th of August. The afternoon session is the pick of the entire forecast. We get a clean 6 ft swell from the south, a solid 11-second period, and best of all, light cross-offshore winds from the east-northeast. The combined energy is pumping at 1091, and the comment says it all: "excellent surf conditions for experienced surfers." This is a serious, powerful wave for the crew that knows what they're doing. Inamura Point is a reef break for advanced surfers, and with that kind of power and clean conditions, it’ll be on. Water temps are sitting at 80°F, which is pretty much average for this time of year.
Looking further out, there are a few more promising windows. Monday the 31st of August morning looks clean with a 5 ft SSE swell and cross-offshore wind. Then, the morning of Tuesday the 1st of September is another huge standout. We're talking a 8 ft, 15-second groundswell, light offshore winds from the northeast, and massive energy (2712). This is big, powerful surf – strictly for experts only. This long-period swell will be breaking a bit straight at a beach break, but on a point or reef like this, it'll groom into some proper, heavy lines.
After that, the pattern looks a bit messier with building wind, but there's a final shout for Thursday the 3rd of September morning. Strong offshore winds from the north-northeast (22 mph) will clean up a 5 ft south swell, but that wind is going to make paddling out a real battle. It’s an option for the die-hards.
To sum it up: the first week is a write-off. Your best bets are the afternoons of Saturday the 29th of August and the morning of Tuesday the 1st of September. Those are the only two sessions that have the right mix of size, power, and clean wind.

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.
