The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Inamura Point.
To be straight with you, the next week and a half is a bit of a write-off. We’ve got a long stretch of nothing but tiny, weak swells and poor conditions. From the 30th of August right through until the 5th of September, the swell is barely a whisper, often under 2ft, and the winds are all over the place – onshore, cross-shore, you name it. The combined wave energy is pathetic, often in the 20s and 30s. It’s a frustrating wait, but hang in there.
The first real sign of life shows up on the morning of Sunday, the 6th of September. We see a pulse of 4ft swell from the south, with a period of 14 seconds – that’s proper groundswell energy. The wind is fresh offshore from the north, so the lineup will be clean. The energy jumps to 491 (moderate), and by the afternoon it’s up to 525. It’s still a bit marginal, but it’s the first time we’ve got something to work with.
Now, the standout window is Monday, the 7th of September. The morning is looking the best of the whole run. The swell builds to 4ft from the south, with a 14-second period, and we have a moderate offshore breeze from the north-northeast. That’s going to produce clean, well-shaped waves at Inamura Point. The combined energy is 638 (moderate), and while the swell is a bit on the bigger side for beginners, it’s a solid, surfable size for anyone with some experience. The afternoon stays clean, but the wind shifts more cross-offshore, so make the most of the morning.
The good energy doesn’t stop there. Tuesday the 8th holds 4ft from the south, but the wind is lighter and more cross-off, so it’s a bit less clean. Wednesday the 9th is a step down in quality. But then we get another cracker on Thursday the 10th of September. The morning brings 4ft from the south-southeast, with a 12-second period, and a gentle cross-offshore breeze. The energy is 518 (moderate), and the conditions are flagged as very good. Friday the 11th morning also looks promising, with 4ft from the south, 13-second period, and near-calm winds. The energy is 543 (moderate). The afternoon gets chopped up, so again, dawn patrol is your friend.
After that, it tails off quickly. By the 12th and 13th, we’re back to smaller, weaker swells and less clean conditions.
So, the call is: Monday the 7th of September morning is the best on offer, with Thursday the 10th and Friday the 11th mornings as solid back-up options. The water temp is a touch warmer than normal at 82°F, which is nice for the first session. Inamura Point is an advanced reef break, and it can get crowded, so expect some company when the swell kicks in. The optimum swell direction is from the south, and that’s exactly what we’re getting. It’s been a long wait, but there’s a couple of good windows to make it count.

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.
