The Lowdown

G’day, Rusty here, and I’ve got a look at what’s coming up for Inamura Point over the next couple of weeks. Honestly, it’s a bit of a slow start, but there’s a real window of opportunity lurking in the middle if you’re patient.

Right now, we’re looking at a pretty flat spell. From Monday the 31st of August through to Monday the 7th of September, the swell is tiny. We’re talking ankle to knee-high at best, around 1ft to 2ft, mostly from the SSW. The wind is a mix of cross-off and onshore, so it’s not doing us any favours. The combined wave energy is weak, sitting between 16 and 130 (weak to moderate), so there’s just not enough oomph to get excited about. It’s a good time to fix your dings or clean the wax off.

Then, things start to stir. On Tuesday the 8th of September, we finally see a pulse. The morning brings a 3ft swell from the SE with a period of 11 seconds, and a nice offshore breeze from the NNE at 12 mph. The wave energy jumps to 257 (moderate), and the wind is offshore, keeping it clean. The afternoon sees the swell tick up to 4ft, but the wind swings cross-shore, making it a bit less appealing. Still, the morning is your best bet for a decent paddle.

Wednesday the 9th builds on that. The morning is clean with a 3ft SSE swell, but the afternoon is where it gets interesting. The swell jumps to 6ft from the SSE, with a period of 12 seconds, and the combined energy hits 863 (strong). The wind is cross-off from the ENE at 12 mph, so it’s clean. This is a solid groundswell, and for a reef break like Inamura Point, that longer period means better shaped waves. It’s getting serious.

Thursday the 10th is a standout. The morning has 5ft swell from the SSE with a 13-second period, and a fresh offshore breeze from the NNE at 19 mph. The wave energy is 700 (strong). The afternoon gets even better: 6ft from the SSE, 13 seconds, and still a fresh offshore wind. Combined energy is 930 (very strong). This is the kind of day that’ll have you calling in sick. The water temperature is 83°F, which is a touch warmer than normal for this time of year, so you’ll be comfortable in boardshorts.

Friday the 11th holds some size, with 5ft swells in the morning and a clean cross-off wind, but it drops off a bit in the afternoon as the wind turns onshore. Saturday the 12th is the real gem. The afternoon sees a 6ft swell from the S, period of 10 seconds, and a gentle cross-off breeze. The combined energy rockets to 1133 (very strong), and the conditions are clean. At 6ft, this is a solid size for advanced surfers, and the reef will handle it well. The morning is also good at 6ft, but the wind is lighter.

After that, it fades fast. Sunday the 13th brings rain and dropping swell, and by Monday the 14th we’re back to tiny, weak waves. The second week is a write-off, with nothing over 2ft and poor conditions.

So, the standout is Saturday the 12th of September, afternoon session. A 6ft swell from the south, clean conditions, and massive energy. Thursday the 10th is a close second with that offshore wind. Inamura Point is a reef break for advanced surfers only, and it’s fairly consistent, but it can get crowded. With this quality, expect some company.

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.
