The Lowdown

Alright, Rusty here. Let's have a look at what's on offer for Inamura Point.

Right off the bat, I gotta be straight with you – this 16-day window is a bit of a slow burner. The surf starts off tiny. For the first several days, from Sunday afternoon, August 30th, right through the start of the first week of September, we're looking at flat, weak conditions. The swell is barely a ripple, with combined energies down in the 20s and 30s (weak energy). The wind isn't helping either, mostly blowing onshore or cross-shore. The water’s running a touch warmer than normal for this time of year at 83°, but there’s no surf to enjoy it in. You’re probably better off finding something else to do.

We get a little tease of something on Thursday the 3rd of September, with a bump in swell to 3ft, but it's coming from the south with an onshore wind hitting 19 mph, and a period of just 4 seconds. That’s wind chop with no power.

The first sign of life doesn’t really show up until Sunday, September 6th. The swell picks up to 3ft, and the period jumps to 13 seconds. The combined energy hits 395 (moderate wave energy), but with a strong north-northeast breeze at 22 mph and cross-offshore winds, it’s going to be clean-looking but still raw.

Now, here’s where things start to get interesting. The standout in this whole outlook is Tuesday, September 8th. This is the day. On Tuesday morning we’ve got a clean 4ft swell from the SSE, with a 9-second period, and the wind is a light cross-offshore from the NNE at just 9 mph. But the real magic is Tuesday afternoon. The wind goes glassy – dead calm from the SSW at 3 mph – and the swell holds at a clean 4ft. The combined energy is 267 (moderate wave energy). The conditions are described as glassy. This is the time to go. It’s the best call of the whole period.

After that, the swell starts to pump up in size but the quality drops. Wednesday, September 9th sees the swell jump to 8ft and then 10ft from the SE with a 12-13 second period. The combined energy is massive – 2,215 and then 3,810 (strong to very strong wave energy). This is expert territory. It's too big for beginners and even intermediates will be in over their head. The wind stays offshore or cross-offshore, so it will look tempting, but at this size, Inamura Point, which is an advanced reef break, is going to be heavy. Also, crowds are often here, so expect a crew if you're up for it.

Towards the end of the run, from Friday, September 11th, the swell drops back down to the 4ft range with a clean 12-second SSW interval and a moderate offshore wind. It’s surfable, but nothing compared to that Tuesday. There’s a nice glassy morning on Sunday, September 13th, but the swell is small at 3ft with a 10-second period.

So, to wrap it up: the first week is a washout. The best surf by a long shot is Tuesday afternoon, September 8th. Get out there when the wind drops to glassy and the swell is a fun 4ft. The big stuff on the 9th and 10th is for the experts only.

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.
