The Lowdown
Alright, this is Rusty. Let's take a look at the upcoming swell window for Inamura Point.
First thing's first: for the next week or so, we're looking at a whole lot of nothing. Tiny, weak slop with poor conditions. You'll be staring at flat, bumpy water more often than not. This is a long stretch of quiet, so don't bother paddling out until we get some real energy.
The real story here is a late-month pulse of solid groundswell that's got some serious weight behind it. Mark your calendars for Monday, August 24th. We're talking about a clean, glassy morning with a 5ft swell from the SSE, but with a period of 17 seconds. That's proper long-period groundswell, and the energy readings are through the roof at 1328. This is for experienced surfers only, as that size and power will be a handful. The wind is dead calm, making for pristine conditions. The water is sitting at a normal 81° for this time of year.
This swell builds into Tuesday, the 25th, with the morning offering a standout 7ft SSE swell, still with a very long 16-second period and calm, glassy conditions. The energy is massive at 2396. This is pure, powerful groundswell. It's going to be a heavy, testing day, but for the crew who know what they're doing, it's the best on offer. The afternoon will see the onshore kick in, so get it in the morning.
Wednesday the 26th still has a solid 5ft S swell in the morning with glassy conditions, and Thursday the 27th offers a 6ft SSW swell with clean, cross-offshore winds. The size calms down after that, but the wind becomes a problem again.
The other notable spike is on Monday, August 31st. The afternoon shows an 8ft SSE swell with a 14-second period, and the energy is a staggering 2781. However, the wind is onshore and the conditions are described as marginal, so it's a high-risk, high-reward kind of day for the experts only.
So, to wrap it up: sleep in for the first week. The real action is the Monday the 24th and Tuesday the 25th of August mornings. The 24th is a great start, but the 25th morning is the true standout for powerful, clean groundswell. Just remember, this is a spot for advanced surfers, and it can get crowded, so be ready to share the peak.
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.
