The Lowdown

Alright, Rusty here, checking in on our local stretch for the next couple of weeks. First up, we’ve got a bit of a slow start before things get really interesting.

The early part of the week will be slim pickings. That morning on Tuesday the 8th of September, we see a bit of a spike with chest-high 4ft swell from the south, but the wind is from the SSE, producing glassy conditions. The vibe is nice, but it's not the highlight of the outlook. After that, the surf gets smaller and the wind turns onshore, so we’re looking at a long gap with very little to get excited about from Tuesday afternoon all the way through to the end of the week and into the weekend.

Things start to look a little more promising towards the end of the window. On Sunday the 20th of September, there’s a massive change in the ocean. We start to see a long-period groundswell from the southeast, with a period of 19 seconds, pushing some moderate wave energy (414) by the afternoon. The wind is offshore from the north, so it’s clean. This is a taste of what's coming.

The real standout is Monday the 21st of September. This is the one to circle on your calendar. The swell builds to a solid 5ft, still from the southeast, with a very long period of 15 seconds. The wind stays offshore from the NNE, so Inamura Point should be firing with clean, powerful lines. The combined energy is strong, well over 800 in the morning and over 1000 by the afternoon. This is a reef break for advanced surfers, and with that long-period swell, it’s going to be proper. Because it’s a reef, it will handle that long period energy better than a beach break, so the shape could be incredible. This surf is for experienced guys only, though.

That energy carries into Tuesday the 22nd of September with even bigger sets—6ft to 7ft from the SSE, still a very long 16-second period. The morning is clean with light offshore winds, but the wave energy is massive (1738). This is serious, expert-level surf. It will be a bit of a beast, but for those charging, it’s the best on offer. By Wednesday the 23rd of September, the swell is pushing 8ft, and the wind is getting tricky, so the quality may drop off a touch, but it’s still big.

To be honest, that Tuesday the 22nd of September morning session looks like the pick of the bunch—big, powerful, long-period groundswell with clean light wind. Get on it if you’ve got the skill. It doesn’t get much better than that.

Remember, the first week is a write-off for decent surf, so don't bother paddling out until that Sunday the 20th of September at the earliest. Until next time, this is Rusty signing off.

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.
