The Lowdown
Alright, let’s get into it. Rusty here, and I’ve gotta be straight with you – the next week and a bit is pretty grim for Inamura Point. We’ve got a long dry spell before anything really gets going, so don’t rush to wet your wetsuit just yet.
Right now, from Friday the 11th all the way through to Thursday the 18th, it’s basically a write-off. Tiny swell, poor surf conditions, and most days the energy’s barely registering. The water’s sitting at 82° which is a touch warmer than normal for this time of year, so you might feel a bit of a tropical bath, but that’s where the good news ends. Through Friday and Saturday we’ve got light cross-off breezes keeping things clean, but with swell heights around 1 to 2 feet and periods under 8 seconds, there’s just no push. Sunday morning looks glassy and clean, but again, tiny 1ft from the SE – nothing to write home about. Tuesday the 15th actually goes glassy with near-zero wind, but again, 1 to 2ft from the SSE with periods of 6 to 8 seconds – it’s basically a lake. A week of that, and you’ll be twiddling your thumbs.
Now, here’s where it gets interesting. Friday the 18th morning we finally see a pulse of energy, with combined swell energy climbing to 104 – moderate – and a long period of 18 seconds from the SE. Swell height is still only 1ft, so don’t get too excited just yet. But by Friday afternoon, things start looking up: 3ft from the SSE with a 16-second period and energy of 486. Still marginal, but it’s a tease of what’s coming.
The standout window kicks off Saturday the 19th morning. Swell jumps to 7ft from the SSE, period 15 seconds, and energy surging to 2144 – strong. This is proper groundswell. It’s clean with cross-off winds from the NE at 12 mph. This is big for Inamura Point, and with that direction lining up nicely with the optimum S swell direction, this is the best on offer. It’s advanced-level stuff though – over 7ft on a reef break with that long period means only experts should be out there. Saturday afternoon holds similar quality at 7ft.
Sunday the 20th afternoon is another standout. Swell at 7ft from the S, 14-second period, and 1909 energy, but now we get offshore wind from the NNE at 9 mph. That’s clean, lined-up, and with the tide cooperating, it’s excellent for experienced surfers. Crowds can be an issue here – it’s often busy – but with this quality, you’ll be sharing it with a few keen locals.
Monday the 21st morning is absolutely glassy – zero wind from the WSW – and a massive 8ft from the S, 14 seconds, and energy of 2736. That’s very strong. The reef will be handling it, but it’s strictly for experts. That afternoon, the wind swings onshore from the SSW at 16 mph and the swell jumps to 13ft with 15-second periods – it’ll be a washing machine and pretty dangerous. Not recommended.
After that, it fades. Tuesday the 22nd still has some clean 5ft swell but energy drops, and by Wednesday the 23rd we’re back to tiny 2ft and fading. The end of the month looks messy with strong onshores and blown-out conditions.
So if you’re hanging for a wave, your window is Saturday the 19th through Monday the 21st morning. The best of the best? Sunday the 20th afternoon at Inamura Point – clean offshore wind, solid 7ft S swell, and that long-period groundswell pushing in. That’s the one. Keep your wits about you – it’s a reef break and the crowd factor is real.
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.
