The Lowdown
Yo, Rusty here. Let’s talk about what’s shaping up at Inamura Point.
Right off the bat, we’ve got a bit of a flat spell to start. Saturday and Sunday, August 22nd and 23rd, are pretty much a write-off – tiny swell around 1 ft to 1 ft with poor conditions and onshore wind. Not worth paddling out.
Things get interesting on Monday, August 24th. That Monday morning is the standout of the entire outlook. We’ve got a 2 ft swell coming from the SSE, but that period jumps to 19 seconds – that’s a long, groundswell pulse. The combined energy is strong at 482, and the wind is glassy. This is the kind of morning where you’ll be alone on the water, and the ocean will feel like silk. The water temp is 81°, which is about average for this time of year. The wave energy is moderate (482). Just a heads up: with that long 19-second period, the reefs and points will be where it’s at, as beach breaks can get weird and straight. For Inamura Point being a reef setup, this could be gold. Expect some clean, lined-up waves for the advanced crew.
The swell builds from Monday afternoon into Tuesday and Wednesday, but the wind goes onshore and howling. Tuesday morning has 5 ft at 14 seconds from the S, but the cross-on wind kills it. Tuesday afternoon the wind is onshore and 16 mph, and the swell jumps to 6 ft – that’s getting big, more for experts, but with that wind it’s just a mess. By Wednesday, we’ve got 4 ft to 5 ft but with 12 to 25 mph winds onshore. The combined energy hits 1630 on Wednesday arvo – very strong wave energy – but it’s a kite-surfing session, not a paddle session.
Thursday through to early September is a mixed bag. Thursday morning drops to 2 ft, but you’ve got onshore wind from the SSW. Not good. Friday, August 28th, has some surfable but ordinary 3 ft waves with clean cross-off wind from the NE – it’s not great, but you could get a few if you’re desperate.
Now, looking further out, there’s a promising window on Thursday, September 3rd and Sunday, September 6th. September 3rd morning sees 5 ft from the SSE at 11 seconds, with a clean NE cross-off wind. Combined energy is moderate at 526. This is solid for a reef break, but keep in mind it’s over a week away, so the forecast confidence drops. September 6th morning also looks similar – 5 ft from the SSE, 14-second period, clean NE wind, with combined energy at 969 (strong). That’s a more confident call for a good session, but again, long range.
So, the absolute best bet is Monday, August 24th morning. That glassy, long-period, clean swell is the one to circle on the calendar. The second best is likely September 3rd or 6th mornings, but keep an eye on the wind.

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.
