The Lowdown

G’day, I’m Rusty. Let’s get into it.

We’re looking at a pretty quiet 16-day window here. The first proper chance of a wave doesn’t show up until Monday the 24th of August, and even then it’s a bit of a tease. There’s a real dry spell at the start – nothing worth paddling out for on Sunday the 23rd. After that, the surf trickles in but conditions are often messy or too wind-affected. The standout window looks to be around Friday the 4th of September, but we’ll walk through it in order.

Inamura Point (Japan) – a reef setup that only the advanced crew should be looking at. The water temp is about average for this time of year, nothing wild.

Sunday the 23rd of August: forget it. Rain showers and a cross-off breeze with tiny 1ft SSW swell (combined energy 36) – poor surf conditions. The afternoon’s no better, 1ft SE swell and cross-on.

Monday the 24th: morning sees a jump to 3ft SSE swell, clean offshore wind from the south at 6 mph. The period’s a very long 15 seconds, which could set up some nice lines on this reef – but the combined energy’s moderate at 399, and the score’s only marginal. It’s not firing, but it’s the best we’ve seen so far. The afternoon turns poor again with strong onshore wind.

Tuesday the 25th: morning offers 5ft S swell, 14-second period, and light offshore – combined energy’s strong at 1229. This is solid, but the score is still marginal. It could be okay for experienced surfers but the onshore wind kicks up hard in the arvo.

The rest of the week through to Friday the 28th is mostly onshore slop or weak. Friday the 28th afternoon finally shows some promise – glassy conditions, 3ft S swell, 9-second period, combined energy 122, light wind. The score says surfable but ordinary. It’s clean though, and that counts for a lot.

Saturday the 29th: morning stays clean with light cross-off wind, 2ft S swell, 10-second period, combined energy 103. Again, just ordinary but clean.

Then there’s a long stretch of tiny, weak waves right through to the end of the month. A few glassy windows but nothing with any push.

The real standout is Friday the 4th of September afternoon. Inamura Point picks up 4ft S swell, 13-second period, with a moderate offshore wind from the north-northeast at 16 mph. Combined energy’s moderate-strong at 549, and the score says expect very good surf conditions. This is the one to aim for – clean, solid, and the swell direction aligns nicely with the optimum from the south. It’s a reef, so the longer period should give proper lines. Crowds are often here, so expect company.

Before that, Thursday the 3rd of September has clean but more marginal offerings, and after the 4th, it drops back to small and ordinary through to Monday the 7th of September.

All up, the pick of the period is the afternoon of Friday the 4th of September. Mark it in the calendar. Everything else is small and ordinary or just plain poor.

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.
