The Lowdown
Alright, Rusty here again, switching over to imperial for those who think in feet and miles.
The next 16 days at Inamura Point start quiet, then build into a solid run of clean, powerful surf. The highlight window is for experienced surfers only when the size peaks.
First rideable swell appears on Saturday, September 19th, but it’s marginal. Waves around 5ft from the southeast with a 14-second period, offshore winds from the NNE. Energy is moderate at 961. Not bad, but not great.
The real green light comes Sunday, September 20th. Morning shows 5ft SSE swell, 13-second period, with fresh offshore winds keeping the face clean. Energy is 947 (moderate). Conditions are very good, but the next day is even better.
Monday, September 21st is the pick of the fortnight. Waves hit 6ft from the south, 13-second period – that’s proper groundswell. Combined energy is 1312 (strong). Winds are light from the NNE, glassy and clean. This is excellent surf, but definitely for experienced surfers due to the power and size. Crowds are likely, so get there early. Swell direction matches the optimum for Inamura Point.
Tuesday, September 22nd morning holds solid with 6ft SSW swell, 14-second period, and light NNE winds – energy at 1043 (strong). Afternoon gets messy with thunderstorms and cross-shore wind, and size jumps to 7ft (only for experts).
By Wednesday, September 23rd, the swell is fading fast. The rest of the week and into the second week is mostly small, weak, and poor. A tiny window on Friday, September 25th afternoon offers glassy conditions on 2ft SSE swell, but it’s very ordinary.
The second week is a dud. Small 2ft swells with light offshore winds on Monday, September 28th morning, but energy is weak at 113. Not worth suiting up.
Water temp is about normal for this time of year.
Bottom line: circle Monday, September 21st morning. Clean, strong, south swell – the best of the run. Sunday the 20th is a solid warm-up. After that, it’s back to small stuff.
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.
