The Lowdown
Alright, surfers, ol' Rusty here with a look at what's on the menu for us. Let's be honest, it's a pretty flat start. We've got a real dry spell to kick things off, so don't be in a rush to wax the board.
The first real sign of life is on Sunday afternoon, the 23rd of August. Up until then, it's just a whole lot of nothing with tiny, messy waves. That Sunday afternoon, we get a little glassy window with a 2 ft swell from the SSE, period of 14 seconds, and the energy is pretty weak at 165. It's surfable, but only just, and very ordinary.
The first standout is shaping up for Monday morning, the 24th of August at Inamura Point. We've got a clean 6 ft SSE groundswell rolling in with a long 16-second period, and the energy is ramping up into the moderate range at 1580. The wind is onshore, so it won't be perfect, but the swell is there. This is a reef break and it's exposed, so that long period energy will wrap in nicely. The water temp is sitting at 80°, which is pretty much average for this time of year.
Now, the real power shows up mid-week. Tuesday the 25th sees that swell building, with a solid 8 ft S swell in the morning, period 16 seconds, and energy hitting 3660 – that's getting strong. This is expert territory. The wind is onshore again, but if you're a confident charger, the morning of the 25th could be worth a look. The afternoon gets too big and messy.
The biggest push of energy comes in on Thursday the 27th of August, with a 12 ft to 13 ft SSE swell. The energy readings are massive – over 5000 – but it's all onshore wind and the period drops to 11 seconds. For a reef break, that's a lot of raw power but not much finesse. This is serious, heavy water for experts only.
We finally get a solid window of clean conditions. Saturday the 29th of August morning, the wind swings offshore from the North at 12 mph. The swell has dropped to a more manageable 5 ft from the SSE, with a short 8-second period. The energy is moderate at 535, and it's clean. This is a much better bet for a good session. The crowd profile at Inamura Point is "often," so expect a few people out.
Then Sunday the 30th of August morning looks even better. A clean 5 ft SSE swell, 12-second period, with a light cross-offshore breeze from the NE at 6 mph. Energy is 692. This is good, clean, lined-up surf. That's the one to pencil in.
After that, the swell fades into the first days of September. A few small, clean pulses with offshore winds, but the swell is too small to get excited about, and the wind gets too strong to paddle into.
So, to wrap it up: the first week is a slow burn, but the 24th to the 25th has the size for the experts. The real sweet spot for the general surfer is the morning of Saturday the 29th and definitely the morning of Sunday the 30th – that's your best bet for clean, fun waves.
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.
