The Lowdown
G'day, Rusty here. Look, I'll level with you – the next ten days or so are pretty grim for a paddle. We've got a long, flat spell ahead before things finally wake up. From this Sunday the 16th to the Monday the 24th, it's all tiny, weak waves with poor conditions. Don't bother getting the wetsuit wet; you'll be frustrated. The combined energy is often under 100, barely enough to push a sea lion around. Then things start to get interesting, but not without a few hiccups.
On Tuesday the 25th, we see a pulse of energy arrive at Inamura Point. The swell jumps to 6 ft from the SSE with a cracking 15-second period – proper groundswell. Combined energy is a solid 1289 (moderate to strong). The morning looks the pick with a light easterly breeze keeping things clean. It's a marginal call, but for an advanced crew, this is the first real window. Given the long period, this reef setup should handle it well. Water temp is about average for this time of year.
Wednesday the 26th holds similar size, around 6 ft from the SSE with a 14-second period, and the wind swings to a cross-offshore NNE blowing at 12 mph, keeping the surface clean. Energy hangs around 1277. Still a marginal rating, but again, for the advanced surfer, this is a decent option.
Now, Thursday the 27th is a write-off. A proper gale hits, with 40 mph winds from the north. Swell jumps to 7 ft with energy over 1935, but the wind is howling. It's dangerous, not fun.
But hold onto your leash for Friday the 28th. That's the standout. Inamura Point fires up. Early morning, we've got 8 ft of SSE swell with a 14-second period – that's a solid, powerful groundswell. The combined energy is a massive 3009 (very strong). And the wind? Glassy offshore from the NE at only 6 mph. This is excellent surf for experienced surfers. For the crew who know this reef, this is the session to circle on the calendar. The size is over 8 ft, so it's experts only – beginners, stay on the beach.
Saturday the 29th is still pumping, with 10 ft from the SSE and 13-second period, energy around 4250, but the wind is a fresher 19 mph cross-offshore. It’ll be big and powerful, but wind will add a bit of texture. Still a heavy day for the well-equipped.
After that, the swell drops back down and the winds go onshore again into the end of the month. So the call is clear: endure the flat spell, and then nail Friday the 28th at first light. That's the one.

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.
