The Lowdown
Alright, let me tell ya how it’s shaping up for Inamura Point. This reef break has some serious potential, but we’re looking at a long dry spell before the real action kicks in.
Honestly, for the next week and a half, it’s pretty grim. From now until the morning of Saturday the 22nd, there’s nothing worth paddling out for. The swell’s tiny, mostly under 2ft, with short, weak periods. Winds are all over the place – cross-off, cross-on, onshore – just a messy, uninviting picture. You’d be wasting your time. That’s a solid 7-day gap of no-go.
Things start to whisper on Saturday morning the 22nd. We get a glassy 2ft swell with a 10-second period from the SSW. It’s not going to blow your mind, but the combined wave energy is only 90, so it’s weak. It’s the first sign of life, and the glassy wind means it’ll be clean, but it’s a very ordinary, small day.
Now, here’s the standout – and it’s a big one. Circle Monday the 24th and Tuesday the 25th. This is the moment. On Monday morning, a solid 6ft swell pushes in from the SE with a very long 17-second period. The energy reading is a massive 1746 – that’s strong. It’s a groundswell with real grunt. Monday afternoon gets even better: a 6ft SE swell, still at 17 seconds, with glassy wind. For a reef like Inamura Point, that long-period SE groundswell is going to wrap in beautifully and set up some excellent, powerful lines. The water temp is about average for this time of year at 81°F, so no thermal worries. Keep in mind, at that size, it’s for experienced surfers – beginners should sit this one out.
Tuesday the 25th keeps the energy high. Morning sees 8ft from the SSE with a 15-second period and clean cross-off wind (2274 energy). The afternoon is almost identical, still with clean cross-off wind. This is deep, solid, world-class reef surfing potential. If you can only pick one session, Monday afternoon’s glassy conditions on that long-period swell are the absolute cream of the crop.
Wednesday the 26th morning holds strong at 8ft from the SSE with a 15-second period – very heavy, for experts only – but the wind stays clean cross-off. The energy is a staggering 2938. Wednesday afternoon, the swell bumps up to 10ft from the SSE, but onshore wind kicks in and blows it out.
After that, the quality drops fast. Thursday and Friday the 27th and 28th see the swell fade and strong, choppy onshore winds ruin the surface. The rest of the window is tiny and weak again.
So, to wrap it up: suffer through the doldrums for a week, then get ready. Monday the 24th and Tuesday the 25th are your absolute best bets. The swell direction matches the optimum S direction for the break, the periods are long and powerful, and when the wind is glassy or clean cross-off, this reef will fire. The crowd factor is “often,” so expect company, but for waves like that, it’s worth it.

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.
