Alright, let’s get into it. Rusty here.

Right now, it’s pretty much flat for the next few days. We’ve got a real slow start, nothing worth paddling out for until Monday morning, July 6th, and even then it’s just knee-high dribble with weak energy (87). You’re better off waiting.

The real story starts to build from Tuesday, July 7th. We see a pulse of long-period southern hemi groundswell pushing in. Tuesday morning brings clean 3ft waves from the SSE, with moderate wave energy (507) and a light offshore wind from the NE. That’s a solid pick-up, and by the afternoon, it’s pushing into the 5ft range with strong energy (1214) and still clean. Good signs.

Now, the standout window really hits Wednesday, July 8th and Thursday, July 9th. Wednesday morning is the best on offer here: 7ft of clean, long-period SSE swell (17 seconds), with that NE offshore breeze making it glassy. The combined swell energy is very strong (2282). That’s proper groundswell for Inamura Point (a reef break, advanced only), and with that long period, the waves will have shape and power. Expect clean, well-defined lines. It’s a reef, so it’ll handle the long period just fine. For the advanced crew, this is your session.

Thursday holds similar size, around 5ft to 6ft, still with long period and clean morning conditions. The energy remains strong (1641-2187). Friday morning, July 10th, pushes up to 8ft from the south with very long period (17 seconds) and very strong energy (3088). Cross-shore wind keeps it rideable, but that size is starting to get serious – expert level only.

After Friday, the onshore winds kick in from the south, and the quality drops. Saturday and Sunday, July 11th-12th, see messy, onshore conditions on a dropping swell. By Monday July 13th, it’s back to small, poor surf with moderate breeze.

There’s a brief return of clean conditions on Tuesday morning July 14th, but the swell is tiny (2ft, 79 energy). Not worth a special trip. The rest of the outlook through to July 19th is mostly flat or blown out, with only a possible glassy moment on Sunday July 19th morning with 2ft swells – but energy is weak (75).

Water temp at Inamura Point (Japan) is 74°, which is about 1° cooler than average for this time of year – nothing unusual, just a touch on the cool side. Crowds are likely here when the swell is good, so expect company on the peak days.

Bottom line: Wednesday morning July 8th is the standout. Big, clean, powerful. Thursday and Friday mornings are also very good for experienced surfers. The rest is a long wait.

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.
