The Lowdown
Alright, this is Rusty checkin' in from the Inamura Point area. Let's be real with you, it's been a tough stretch and it's gonna stay that way for a while.
We're looking at a pretty lean 16-day window here. Right now, and for the next week or so, the ocean is just not cooperating. The swell is tiny, the wind is mostly wrong, and the energy is just weak. It’s gonna be a long wait for anything decent.
The first bit of action we see is a tiny pulse on Wednesday morning, August 12th. We’re talkin’ a 2ft SSW swell, but it's short period at 10 seconds, and the energy is weak (80). The wind is light offshore though, so the surface will be clean. But honestly, it's barely surfable and the conditions are very ordinary. It’s a small window for a longboard, and that’s about it.
The rest of August and into the third week is a write-off. The swell drops to 1ft or 1ft, the wind keeps shifting around, and the scores are all zeros. There's a glimmer on Thursday morning, August 20th, with glassy conditions, but again, the swell is a pathetic 1ft from the SSE. Not worth paddling out for.
Now, hold on to your boards because Friday, August 21st, is where things get interesting. The morning brings a sudden jump to a 4ft SSW swell with a 7-second period. The energy is moderate (144), and the wind is a clean cross-offshore from the NE. This is your standout window. The water is a warm 82°, which is about normal for this time of year. But here's the catch – Inamura Point is a reef break for advanced surfers. That 4ft swell might be manageable for the experienced crew, but it'll be a bit much for beginners. The wind is good, and the conditions should be clean, but the short period (7 seconds) means the waves won't be the most powerful or well-shaped. It’s a classic case of “get it while you can.”
The afternoon of the 21st sees the swell jump to 5ft, but the wind swings onshore from the S, turning it into a messy, un-surfable mess. That’s a no-go.
After that, the surf drops off again. The energy fades, the wind gets messy, and we’re back to tiny, poor conditions for the rest of the forecast period. The window on the 21st is the only real shot, and it's a short one. It's a promising but less certain long-range standout, so keep an eye on it.
So, to sum it up: the next week is a no-show. The one real chance is Friday morning, August 21st, at Inamura Point, with a 4ft SSW swell and clean offshore winds. It’s not perfect, but it’s the best we’ve got.
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.
