The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Inamura Point over the next couple of weeks.
Right off the bat, I gotta be straight with you: the surf window is pretty much a bust for the first week. We’ve got a bit of a pulse on August 6th with a solid 6ft S swell, but it’s blowing straight onshore from the south at 6 mph. That’s messy, onshore slop, and the water is warm at 80°, about average for this time of year, but it doesn’t help the waves. The energy is there – a strong 1064 (combined) – but it’s all wind-chopped and the tide is likely working against it. Not worth paddling out for.
That swell fades fast. Friday the 7th and Saturday the 8th see the size drop from 5ft down to 3ft, and the wind stays onshore or picks up to a moderate 12 mph. The energy drops from 962 down to 267. It’s all poor surf conditions, mate. For the rest of the first week and into the second, we’re looking at tiny waves: 2ft, 2ft, and even 0.7ft, with clean offshore winds on a few days like the 11th and 13th, but the swell is just too small to do anything on. The energy is weak, in the 30-80 range. There’s a long stretch of no real surf from the 8th through the 19th.
The only real blip in the radar comes on August 20th, Thursday morning. We get a 2ft SE swell, period 10 seconds, with a light 6 mph cross-offshore breeze from the northeast. The energy is weak at 123, but the conditions are described as "surfable waves but very ordinary conditions." It’s not a standout, but it’s the only session with a score of 1 out of 10 for the whole run. The water temp anomaly is normal.
The 21st of August, Friday, sees a small bump with a 2ft S groundswell, period 12 seconds, but it’s onshore from the south at 6-12 mph, so poor conditions again.
So, what’s the pick? There is no true standout here. The closest you’ll get to a window is that Thursday morning on the 20th. It’s small, it’s weak, but if you’re desperate and the wind holds, you might get a few grovelly ones. Otherwise, we’re looking at a real flat spell. Inamura Point is a reef break, normally exposed, but with no swell and onshore wind, it’s a no-go. For an advanced crew, the 6ft on the 6th would have been fine for experts, but only if the wind played ball, which it didn’t. This is a long stretch of quiet, and for this area, that’s a fairly normal blank run.
Stay tuned, boys. Forecasts can change, but for now, keep the boards in the car.
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.
