The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid pulse of swell rolling into Inamura Point, but it’s not a straight-up beginner’s paradise. The ocean is going to be a big, powerful machine for a few days, and you’ll need to know what you’re doing to handle it.
This stretch kicks off proper on Tuesday, August 4th. We’re looking at a clean, cross-off wind with a 5ft swell out of the SE at a very long 17 seconds. The water’s sitting at a warm 83°, which is a touch warmer than normal for this time of year. The ocean’s got some serious grunt behind it, with a combined swell energy of 1098, so it’s got push. The conditions are clean, but the forecast flags some tricky tide issues, so you’ll need to time it right. The wave quality is there, but it’s not the best of the window.
The real standout, the one you want to circle on the calendar, is Friday morning, August 7th. That’s where the magic is. We’ve got a 7ft swell from the S, with a 15-second period, and the wind is a light 6 mph cross-off. That’s the recipe for clean, lined-up, proper waves. The combined energy is a chunky 2032, so the ocean is full of power. The forecast says "excellent surf conditions for experienced surfers," and I’m buying that. If you’re an advanced surfer, this is the session to chase. The crowd situation is something to keep in mind though – it’s often packed there, so expect company.
The run-up to that Friday is building. Wednesday, August 5th, the swell bumps up to 7-8ft from the SSE with a 15-16 second period. Still a cross-off wind, still clean, but the wave quality notes are a bit more marginal. It’s going to be big and powerful, but maybe not as perfectly groomed as that Friday window. Over 8ft, this is only for experts. Thursday, August 6th, the swell holds around 7ft, but the wind turns cross-onshore in the afternoon, which will mess up the surface.
After Friday’s high point, the energy starts to fade. Saturday, August 8th, the swell drops to 5ft, but the wind is a problem. It’s onshore in the afternoon and cross-onshore in the morning with rain showers. The quality drops right off. Sunday, August 9th, is clean again with a cross-off wind, but the swell is down to 5ft and dropping, with lower energy (947).
Then we hit a real dry spell. From Monday, August 10th, all the way through to Sunday, August 16th, the swell is tiny, the wind is either a gale or strong offshore, and the wave heights are barely breaking 3ft. You’ll see a few days of fresh offshore winds, but with no swell to work with, it’s a skunk. There’s a gap of about six to seven days here where there’s nothing worth paddling out for.
The very end of the outlook, around Monday, August 17th, into August 19th, shows a tiny uptick. We’re talking 1ft to 2ft swells. It’s surfable, but very ordinary. The conditions are clean, but the wave energy is weak (96 to 70). It’s a far cry from that Friday standout.
So, bottom line: the best day on offer, the one that stands head and shoulders above the rest, is Friday morning, August 7th at Inamura Point. Big S swell, long period, light offshore wind. It’s an advanced surfer’s dream. The rest of the week is a mixed bag of building swell and tricky conditions, followed by a long flat spell. Don’t waste your energy on the small stuff.
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.
