The Lowdown
Alright folks, Rusty here. Let’s have a look at the next couple of weeks for Inamura Point. I gotta be straight with you – this is a tough stretch. We’re looking at a long gap of nothing before things get a little interesting, but even then, it’s a real mixed bag.
The Big Picture
The forecast is a real slow burner. For the first few days, the ocean is basically flat. There’s a solid gap of flatness from now until about the 24th of August. We’re talking about four days of barely a ripple. It’s the kind of calm that makes you check your board for cobwebs. Then, around the 24th, a big pulse of energy shows up, but it comes with some serious wind baggage. The water temperature is sitting at 80°F for the first recording, which is pretty much spot on for this time of year.
The Week Ahead
Forget the first few days. We’re starting Thursday, August 20th, with a tiny 0.7ft SSW swell and 9-second period, but it’s onshore wind and the total wave energy is a measly 14. That’s a hard pass. Friday and Saturday are much the same story – small, weak, and messy. You’d be wasting your time.
Then Sunday, August 23rd, morning brings a funky little cross-offshore wind from the NE, but the swell is still a pathetic 1.0ft. Not worth paddling out for.
The "Maybe" Window
Things start to change on Monday, August 24th. The swell jumps up to 4ft from the SSE, and the period is a solid 16 seconds. That’s real groundswell energy, and the combined energy reading is a massive 1389, which is strong. The problem is the wind is light and cross-onshore, and the forecast calls it "marginal surf forecast or questionable tide conditions." This is the closest thing to a highlight we’ve got. The long period makes it best for a point or reef, but the wind isn’t doing us any favours.
Tuesday, August 25th, the swell peaks at 7ft from the S with a 15-second period. The energy is insane at 2376, but the wind is onshore from the SSW. That’s a big, powerful, messy wave. At 7ft, this is getting into expert territory, but the onshore wind will make it a battle. Wednesday follows with a 7ft S swell, but again, cross-onshore wind and heavy rain making it choppy. This whole stretch from the 24th to the 27th is for experts only, and even then, the wind looks like it’s going to ruin it.
The Final Week
The second week is a bit of a letdown. The swell drops back down. From the 30th of August onwards, we get clean, cross-offshore winds from the NE and NNE, but the swell is tiny – 3ft, 2ft, 2ft. The energy readings are low, between 176 and 278. It’s clean, but there’s hardly any power. The period is around 10-12 seconds, so it’s not total junk, but it’s not going to be a day to remember. A few sessions might be just about okay for a log, but don’t expect much.
The Call
If I had to pick the best of a bad bunch, it’s Monday morning, August 24th. That 4ft, 16-second SSE groundswell is the only real swell we see, and if the light cross-onshore wind lets up, it could be a sneaky good session at Inamura Point. But be warned, the tides might be a factor. It’s the only one that gets a hint of a positive call. The rest of the period is either flat, too windy, or too small.
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.
