The Lowdown
Alright, Rusty here. Let's get into it.
Gonna be a pretty lean stretch for a while at Inamura Point, with the real action sitting out there in the second week. For the next week and a half or so, it's mostly small, junky, and wind-affected, so don't get your hopes up too early.
The first real standout that has my attention is the morning of Saturday, August 23rd. We’ve got a little waist-high pulse coming in from the south at about 2ft, but the real story is the glassy conditions. Dead calm, no wind. For a reef break like Inamura Point, that’s about as good as it gets for the small stuff. The water temp is about average for this time of year, just your standard tropical warmth. It's not going to be pumping, but if you're desperate for a clean little slide, that's your window. Expect some company though, as it can get crowded here.
Now, the big news comes on Tuesday, August 25th. The models are lighting up a serious pulse of long-period groundswell from the south-southeast. We’re looking at a solid 8ft of swell with a 17-second period, which is proper, powerful energy. The combined energy reading is through the roof, so this is a major event. But – and it's a big but – this is a lot of juice. At 8ft on a reef, this is strictly for experienced surfers only. The wind is forecast to be light and cross-shore in the morning, which could offer some windows, but that size and period will make it heavy and challenging. After that, it backs off a touch but stays solid into Wednesday the 26th, with cleaner conditions and a more manageable 4ft from the SSE and light offshore winds. That Wednesday morning session looks like the pick of the whole run for the crew that knows what they're doing.
Outside of those two clear windows, the forecast is pretty bleak. There's a long gap from the start of the period right through until that Saturday morning glass-off, and then another lull before the late-month swell arrives. Just the way it goes sometimes.
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.
