The Lowdown
Alright, Rusty here again, but in feet and miles. Let’s break down Inamura Point.
First few days are dead. From the 14th to the 17th, the swell is tiny or onshore. The 14th gives us a 3ft S swell, but a fresh breeze onshore kills it. The 15th is near flat with onshore wind. The 16th and 17th have clean but tiny waves from offshores – maybe 1ft if you’re lucky. That’s a stretch of no-go days.
Then the 18th afternoon shows a pulse: 3ft SE swell, period 16 seconds, energy moderate (321), and clean offshore wind. It’s marginal but could be worth a surf if you’re local. The 19th gets 4-5ft SE, still with offshore wind, energy building (722-801). Still marginal.
Now, the standout: Sunday the 20th, morning session. Swell hits 6ft from the SSE, period 13 seconds, strong energy (1042). Wind is moderate offshore, so it’ll be clean. This is excellent for experienced surfers. Water temp is around 81°, a touch warmer than usual. Crowds? Likely, since it’s a known spot. This is your best window.
Monday the 21st keeps it going with 6-6ft S swell, very strong energy (1425-1522), offshore to cross-off winds. Still good, just not as perfect as Sunday.
Tuesday the 22nd afternoon goes nuts: 18ft S swell, 16-second period, extreme energy (13581). Wind is strong cross-off, so it’s clean but massive. That’s expert-only territory.
After that, it drops. Wednesday the 23rd is 5ft but onshore and lumpy. The 24th onward is small and weak – 2ft or less for the rest of the month.
So bottom line: Sunday the 20th morning is the call at Inamura Point – clean, solid groundswell, and good energy. Monday the 21st is a close second. The 22nd is a monster for experts only. The rest is not worth your time.
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.
