The Lowdown

G’day, Rusty here. Let’s have a look at what’s shaping up at Inamura Point (reef break, advanced spot, fairly consistent). Gotta be honest, it’s a tough start. The first week is pretty much a write-off – tiny, weak, and mostly messy. You’re looking at a solid six-day gap before anything worth paddling out for shows up. The combined swell energy stays under 100 (33) through the first few days, so there’s just nothing doing.

Friday the 11th through to Thursday the 17th: we’ve got ankle to knee-high slop, period under 10 seconds most of the time, and wind swinging all over the place. A few windows of clean conditions pop up – Monday morning the 14th goes glassy with light S wind, and Thursday morning the 17th goes glassy again – but the swell is still tiny (1 ft, SE, 9 seconds). Not worth wetting a suit for.

Now, keep your eyes on the end of next week. Things start waking up Friday the 18th. The swell lifts to 3 ft (SE, 17-second period) morning, then 5 ft by afternoon, and that long-period groundswell is packing some proper energy – 597 to 1286 in the combined reading. Winds go offshore from the north, clean but breezy. This is where the reef starts to shine, but with size over 5 ft, it’s getting too big for beginners.

The real standout window kicks off Saturday the 19th and runs through Tuesday the 22nd. Saturday morning sees a solid 8 ft SSE swell with a 15-second interval, combined energy at 2360 – that’s strong wave energy. Winds are moderate offshore from the NNE, so you’re looking at clean, lined-up waves. This is excellent for experienced surfers only. Sunday the 20th keeps the quality going: 8 ft (SSE, 14-15 seconds) with light offshore or moderate offshore winds, energy over 2000. Monday the 21st pushes up to 8 ft (S, 15 seconds) – still in the expert zone, winds are cross-off but manageable. Tuesday the 22nd is the biggest of the run: 16 ft (SSW, 13 seconds) in the morning and 12 ft in the afternoon, with strong offshore winds. Combined energy hits 8707 – that’s serious power. Only the most skilled crew should even think about it.

After that, Wednesday the 23rd turns nasty with strong onshore winds and rain, dropping to tiny junk. Thursday and Friday the 24th-25th settle back to flat or near-flat, and Saturday the 26th is still tiny with no juice.

The pick of the whole run? Saturday the 19th morning and Sunday the 20th. Clean, powerful, long-period SSE groundswell at 8 ft, offshore wind, and that reef will be doing its thing. Crowds are possible – it says “often” – so expect company at a spot this good when it’s pumping. Water temps are about average for this time of year, nothing weird going on.

No two ways about it – this stretch is for the experienced crew. Beginners should give it a miss, especially once it hits 5 ft and above.

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.
