The Lowdown

Alright, Rusty here. Let’s have a look at what’s shaping up for Shichigahama.

Alright, to be straight with you, we are looking at a very slow start. For the next several days, from Thursday the 30th of July right through to Sunday the 2nd of August, it’s flat. Like, not worth paddling out for. The swell is tiny, and the wind is mostly on it or all over the place. You’d be better off cleaning the wax off your board.

The first real glimmer of hope shows up on Monday morning, the 3rd of August. We’ve got a clean little pulse coming in from the southeast, with waves around 3 feet. The wind is a clean offshore from the northeast, which is a beautiful thing. The combined energy is building, reading at 438, so it’s got a bit of life, but the swell period is 16 seconds, which is proper groundswell. That’s good for shape and power, but at a river break like Shichirigahama, a long period swell can make it a bit wonky and straight. Still, for a Monday morning session with just the locals out, it’s a solid start. Water temp is 81°, which is bang on average for this time of year.

Now, if you want to talk about the standout, we have to look at Wednesday the 5th of August. That is the one. The morning is showing a solid 10-foot swell from the south-southeast, with a clean, moderate offshore breeze from the north-northeast at 12 mph. The combined energy is huge – we’re talking 4342 – this is serious wave energy. The period is a long 17 seconds, so these are deep-water lines pushing in. This is for experienced surfers only. It’s big, powerful, and with that long period, it might be a bit walled-up on the bank, but for anyone who knows what they’re doing, this is as good as it gets in this window. The swell direction is matching the optimum for Shichirigahama (SSW), so it’s going to be breaking perfectly.

Thursday the 6th holds in that same range, with 12 feet from the south in the morning, but the wind is cross-off and there’s a risk of thunderstorms. It’s still big and raw, but maybe a bit more dicey. For the experts, it’s still game on. By Friday the 7th, the swell drops to a still-chunky 8 feet, and with light cross-off winds, it’ll be clean but still only for the confident crew.

After that, things back right off. Saturday the 8th and Sunday the 9th offer some small, clean walls in the 3 to 4 feet range, which would be fun on a longboard if you’re just trying to stretch the arms. After that, it’s pretty much back to the doldrums for the second week. There’s a bit of windswell from the south and southeast, but the wave heights are tiny and the energy is weak. A few mornings from the 11th to the 14th show clean offshore wind, but the swell just isn’t there.

Bottom line: If you’re a beginner, stay out of the water on that big Wednesday and Thursday – it’s way too much. If you’re an expert, circle Wednesday the 5th of August on your calendar. The rest of the window is mostly flat or too small.

Rusty.

Information about the Shichirigahama Surf forecast

The above surf forecast table for Shichirigahama provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Shichirigahama can be found by selecting the local surf guide option on the grey menu. Our Shichirigahama 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 (Shichirigahama) 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 Shichirigahama 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.

Shichigahama is 6 km (4 miles) from the city of Chigasaki. If you plan a holiday in Kanagawa, look for hotels and other accommodation in Chigasaki. Chigasaki has rooms for a wide range of budgets as well as car hire and transport links.
