The Lowdown
Alright, I’ve looked through the charts for the coming weeks at Inamura Point. It’s a slow grind to start, with about 10 days of pretty flat and ordinary conditions before the ocean finally wakes up.
The first real sign of life comes on Sunday, August 23rd. You’ll see a clean 1.3m SSW groundswell with a 15-second period, light NNE wind keeping it smooth. Swell energy hits 865 (moderate). For a reef break that’s advanced-only, that long period is a good thing – it’ll keep the waves from closing out. This is the standout of the outlook.
Then it builds hard. Monday the 24th brings 1.6m SSE swell with 14-second period, and the energy goes to 1805 (strong). Glassy conditions in the morning. This is excellent, but for experienced surfers only. Afternoon gets bigger at 2.2m, which is pushing limits.
The biggest stuff fires Wednesday the 26th: 2.5m to 3.0m SSE groundswell, 15-second periods, light NE wind in the morning. Energy readings are massive (3202-4348). Experts only. Thursday the 27th peaks at 6.5m, which is way too much for this spot. Friday the 28th settles back to a user-friendly 1.1m.
Water temp is 27°C, about average for this time of year. Expect crowds here when it’s good. The real windows are Sunday 23rd through Wednesday 26th, especially the early mornings. If you can only pick one session, that Sunday the 23rd is your best bet.

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.
