The Lowdown
Alright, Rusty here, let’s talk about what’s on offer for Inamura Point over the next couple of weeks.
Right off the bat, things are looking pretty flat and ordinary. There’s a real dry spell for most of this period. The first few days up to Monday the 7th are basically a write-off—tiny, messy swell with strong winds making it a battle just to get out. Not worth paddling for.
Finally, a flicker of hope shows up on Tuesday morning the 8th. We’ve got a clean 1.5m (that’s about 5ft) swell from the SSE, with a light breeze and moderate wave energy (460). That’s the best we’ll see for a while. It’s still only a 2 out of 10 for quality, but for this stretch, it’s the standout. The south swell direction matches up with the break’s optimum, and with clean conditions, it’ll be the most surfable window in the forecast. The water temp is about average for this time of year.
Wednesday the 9th gets a bit bigger at 1.6m (around 5ft) from the S, but the wind swings onshore and it gets lumpy and choppy. Not your day.
Thursday the 10th morning is another solid option—1.8m (about 6ft) from the S, with a gentle offshore wind and strong wave energy (577). That’s some proper size and power, but it’s getting up there for beginners. This is expert territory with that much juice. The afternoon drops off a bit.
After that, from Friday the 11th onward, it fades fast. Tiny waves, weak energy, and mostly onshore or cross-off winds. A lot of mornings are glassy, but there’s barely any swell to ride. From the 12th right through to the 19th of September, it’s a long stretch of flat to near-flat conditions. Most days have combined energy under 50. You’d be lucky to find a ripple.
So, to wrap it up: your best chance is Tuesday morning the 8th for clean, moderate waves, or Thursday morning the 10th if you’re after size and power but can handle a strong, short-period groundswell. The rest of the run is pretty grim for a paddle surfer.
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.
