The Lowdown

G’day, Rusty here. We’ve got a bit of a slow start for Inamura Point, but there’s some solid action brewing in the second week if you’re patient.

Right now, the water’s a touch warmer than usual for early September – sitting around 82°, which is a little above average for the time of year. Nothing crazy, but you’ll notice it.

The first few days are pretty flat. Wednesday the 2nd and Thursday the 3rd are all onshore slop – tiny 1 ft from the SSW and S, weak energy, and not worth paddling out for. Friday the 4th sees a slight lift with 2 ft from the S, period creeping up to 10 seconds, and a light offshore wind in the morning – clean, but the combined energy is still weak. It’s surfable but very ordinary. Saturday the 5th drops back off with cross-off breezes and small S swell. Sunday and Monday the 6th–7th are mostly rubbish, though Monday morning has a fresh offshore wind on a tiny 1 ft SE swell – clean but barely rideable. Monday afternoon gets a jump in energy with a 2 ft SSE swell, but the cross-onshore wind and chop ruin it.

Then things change. Tuesday the 8th afternoon is where it starts firing – a 10 ft SSE groundswell with a 12-second period, and a solid offshore wind from the north. The combined energy is massive – strong wave energy – and it’s clean. This is big, powerful stuff, only for experienced surfers. Inamura Point is a reef break, and this long-period groundswell will really line up on the reef, though it might get a bit straight at times. Wednesday the 9th keeps the run going with 8 ft to 8 ft from the SSE, periods around 10–11 seconds, and offshore winds all day. Energy is still very strong. This is the standout window – Tuesday afternoon through Wednesday, the 8th and 9th of September. The crowd factor is ‘often’ here, so expect company.

Thursday the 10th through Saturday the 12th fades fast – dropping back to 4 ft and below, onshore winds, and choppy conditions. Not your window. Sunday the 13th and Monday the 14th are tiny again with clean but weak 1 ft–1 ft S swell.

Then Tuesday the 15th throws up another big pulse – 8 ft from the SE with a very long 15-second period and combined energy of 2347. That’s serious groundswell, and with a clean light cross-off wind, the reef should hold it well. This is the second standout – Tuesday the 15th. It’s further out, so less certain, but promising. Wednesday the 16th still has decent 5 ft–4 ft SE to S swell with offshore winds, but energy drops. Thursday the 17th fades with onshore winds again.

So the two best windows are Tuesday afternoon 8th through Wednesday 9th, and Tuesday the 15th. If you’re an experienced surfer, those are the sessions. Beginners should sit it out – the 10 ft and 8 ft stuff is too big and the reef isn’t forgiving. When it’s small and clean, like Friday the 4th morning, there’s a gentle option, but it’s not worth a special trip.

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.
