The Lowdown
Alright, Rusty here with a look at what’s ahead for Inamura Point.
Honestly, it’s a bit of a frustrating stretch. We’ve got a whole lot of days with onshore wind and messy conditions, but there are a couple of windows where it all comes together. The water temp is sitting right on the average for this time of year at 81°, so no need to worry about a wetsuit.
The first real chance for a decent wave doesn’t show up until Monday, August 24th. Even then, it’s only marginal. The morning has a clean-looking 2ft SSE swell, but it’s a super long period – 20 seconds. That means long waits between sets and it could be a bit straight at this exposed reef point. The energy is moderate (587). The afternoon gets a bump to 4ft from the SSE with a 16-second period, but the south wind picks up to 12 mph and ruins it. That swell energy is strong though (1145).
Tuesday, August 25th morning is where we get our first real stand-out. Swell builds to 5ft from the south with a solid 14-second period. The combined energy is very strong (1315). There’s a light cross-onshore wind from the SSW at 6 mph, which will leave a bit of texture, but for a reef point like Inamura, this is the best size and energy we’ll see. 5ft is getting a bit big for beginners though. The afternoon blows out with a strong south wind.
We then hit a nasty run of poor conditions from the 26th right through to the 28th with strong winds and onshore slop. The swell is there, but the quality is shot.
There’s a small glimmer on Friday, August 28th afternoon. The wind swings to a cross-offshore NW direction at 9 mph, cleaning up a 3ft south swell (8-second period). The energy is weak (106), but it’ll be the only clean wave in days. Still, it’s just “surfable” at best.
The first half of the following week looks pretty lackluster, with tiny, weak swell and inconsistent energy. The next real standout doesn’t arrive until Saturday, September 5th. The morning looks promising with a 3ft south swell, a 12-second period, and a clean cross-offshore wind from the ENE at 9 mph. The energy is moderate (269). It’s not big, but it’s clean and the swell has a bit of punch. Crowds are likely here, so don’t expect to have the place to yourself. The afternoon sees the swell pick up to 3ft with a longer 14-second period, but the wind goes light onshore, making it a gamble.
So, to sum it up: the pick of the bunch is Tuesday morning, August 25th for the size and power, and Saturday morning, September 5th for the clean conditions and a more manageable wave. Everything else is waiting for the wind to play ball.
Stay patient,
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.
