The Lowdown

Alright, mate, Rusty here, looking at what we’ve got coming in for the local stretch.

Right off the bat, the next week is a bit of a write-off. We’re looking at a long, flat, and poor stretch from Saturday the 12th right through to Friday the 18th of September. Those south swells are tiny, weak, and combined energy rarely gets above 40 (43 max). The wind is all over the shop, mostly onshore or cross-off, and the wave comment is shouting "poor surf conditions" every time. It’s a proper lull, so you can leave the boards in the shed for that first week.

The first real sign of life kicks off on Friday the 18th. The wind finally clocks around to a clean, fresh offshore from the North. We’ve got a solid groundswell building from the SSE. Friday morning sees 0.9m (about 3 ft) at a very long 17 seconds, with combined energy of 484 (moderate). By the afternoon it’s 1.2m (4 ft) at 16 seconds (765 energy). The comment says "marginal surf forecast" which is just a cautious start, but the wind is gold. The swell keeps building through Saturday the 19th, hitting 1.8m (6 ft) at 14 seconds (1265 energy) in the morning. That’s getting into expert territory at over 1.5m (5 ft), and for a reef break like Inamura Point, that long period (over 15 seconds) means the waves will be lined up and powerful, but you need to know your line.

Sunday the 20th is the standout of this first pulse. We’ve got a solid 1.2m (4 ft) SSE swell at 12 seconds with persistent North-Northeast offshore winds. The energy reading is 570 (moderate) and the wave comment is "expect very good surf conditions." It’s less size than Saturday, but the wind is clean, the period is still decent, and it should be a lot more manageable and user-friendly than the peak of the swell on Saturday. It will be a proper session for the advanced crew.

The swell dips back down into marginal territory through Monday the 21st and Tuesday the 22nd. Tuesday afternoon gets wrecked by a strong cross-onshore from the SSW, and Wednesday the 23rd is a write-off with a gale from the SSW (70 km/h) and a messy 2.5m (8 ft) windswell.

Now, the second pulse is a big one, but it’s a long way off. Starting Thursday the 24th of September, a new SSE groundswell fills in fast. It’s clean in the morning at 1.6m (5 ft) with a 16-second period (1742 energy – strong). Friday the 25th is the real highlight of the whole 16-day window. We’re looking at a cracking 2.4m (8 ft) SSE swell at 16 seconds (2821 energy – strong), with light cross-off winds from the NE and clean conditions. The file flags "excellent surf conditions for experienced surfers," and that’s exactly what it is. That’s big, solid groundswell with good wind. At over 2.5m (8 ft) by the afternoon, it’s really only for the experts. Saturday the 26th gets even bigger, with 3.5m (11 ft) waves (5595 energy – very strong), but that’s a serious, heavy ocean, even if the wind is good.

The water temp is about average for the time of year, nothing wild to report on that front.

Inamura Point is often crowded, so expect company on those good days, especially Sunday the 20th and Friday the 25th.

This is Rusty, signing off.

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.
