The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Shichirigahama over the next couple of weeks.
Straight up, it’s looking like a pretty quiet period for the river mouth. We’ve got a long stretch of tiny, weak surf ahead, so don't get your hopes up for any rippers just yet. The water temp is sitting about average for the time of year, so that’s one small win.
We kick off on Monday the 27th of July, but honestly, it’s a write-off. The swell is a meagre 1.0 ft out of the SE with a weak 10-second period, and the combined energy is a paltry 38. You’re getting a cross-offshore wind, but with no power behind it, you’re just bobbing around. The whole first week is a bit of a dirge, with nothing but tiny, short-period slop. Wednesday the 29th morning goes glassy with a 2 ft S swell, but it’s still only 6 seconds – that’s just windswell wobble. The energy is barely there at 39. It’s a similar story right through to the end of the month.
Into the first week of August, things stay flat. The 1st of August is basically a lake, with 0.7 ft and 0.3 ft waves. You’re better off finding a different hobby for a few days.
Now, there’s a little flicker of life around Monday the 3rd of August. On Monday afternoon, we get a jump to 2 ft from the ESE with a much longer 16-second period. The combined energy climbs to 284, which is a decent moderate energy for the spot. Tuesday the 4th holds similar energy in the 260-276 range, but the wind is a moderate cross-offshore, keeping it clean. Wednesday the 5th of August morning is the best we’ll see – a 2 ft ESE swell with a 16-second period, and we finally get a proper offshore wind from the NE. The energy is 237. That’s a promising window for a clean, long-period groundswell. The thing is, with a period that long and a river mouth setup, those waves might be a bit too straight and fat, but it’s the only real chance for a wave with some shape. The consistency is noted as "inconsistent", so you’ll be waiting for sets.
Beyond that, the surf fades away again quickly. The 7th of August drops back to 1 ft, and the second week is more of the same with weak, short-period S swells and onshore winds. The 11th of August morning goes glassy but on a tiny 0.7 ft E swell.
So, the only standout in this whole 16-day window is Wednesday the 5th of August morning at Shichirigahama. The swell is a small 2 ft from the ESE, but that long 16-second period and the offshore wind (NE at 9 mph) will make it the cleanest and most energetic we’ll see. It’s not a day for the beginners, but for the patient surfer, it’s the one to circle. Expect crowds to be possible as it’s the only decent option. The rest of the time, you’re looking at a long gap of flat, weak conditions, which is a bit of a bummer, but hey, it’s the coast.
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.
