The Lowdown

G’day folks, Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty grim for a proper paddle. We’ve got a long stretch of tiny, weak surf ahead, and it’s going to test your patience. The good news? There’s a light at the end of the tunnel, but it’s a long way off.

We’re looking at a solid run of poor conditions from now through the 24th. The swell is tiny, mostly under 2ft, with periods that are all over the shop, and the energy is weak – we’re talking readings in the 20s and 30s (weak energy). Nothing’s worth getting wet for, unless you just want to float around. There’s a bit of offshore wind here and there, which keeps things clean, but with no waves, clean doesn’t matter much.

The first real glimmer of hope shows up on Tuesday, August 25th. The swell finally starts to show some life. The morning has a 3ft southeast swell with a 14-second period, and the wind is offshore from the north. It’s surfable, but ordinary. Then, Tuesday afternoon is the standout. The same 3ft southeast swell with that long 14-second period (a proper groundswell) rolls in, and the wind goes glassy. The energy reading jumps to 277 (moderate energy) and the conditions finally line up. This is the one to circle on the calendar. It’s not huge, but it’ll be clean and, for this stretch, that’s a win.

The swell bumps up a bit on Wednesday the 26th, with a 4ft southeast swell in the morning, but the wind swings onshore from the southeast, and it gets choppy. Not worth it.

Then we see another pulse on Friday, August 28th. Swell builds to 4ft in the morning and 5ft in the afternoon, coming from the south with an offshore north-northeast wind. The energy is moderate (124 and 189). It looks clean, but the period is short – only 6-7 seconds – so it’ll be a bit crumbly and without much push. It’s surfable, but it’s not going to be a classic.

So, if you’re hanging for a wave, your best bet is that glassy Tuesday afternoon on the 25th. It’s the only time in the next two weeks where everything clicks, even if it’s not huge. The water temp is sitting at 81°F, which is right about average for this time of year, so you won’t need a wetsuit.

For the rest of the period, bring a book. There’s just nothing doing.

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.
