The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Shichirigahama over the next couple of weeks.
Straight up, I’ll be honest with you – this is a tough stretch. We’ve got a solid 16-day window, but the first week and a half is pretty much a write-off for any kind of decent session. The swell is tiny, the energy is weak, and the conditions are just not cooperating. There’s a long gap of nothing really worth paddling out for from the start all the way through to the end of the first week. It’s only really from Monday the 7th of September that we start to see a little glimmer of hope.
The first real sniff of something surfable comes on the morning of Monday the 7th of September. The wind is offshore from the NNE at 12 mph, and we’ve got a small SSW swell running at 1 ft with a period of 12 seconds. The combined energy here is moderate at 115, and that longer period means there’s a bit of push behind it. The waves are there, but it’s very ordinary. The water temperature is a touch warmer than normal at 82°, so you won’t need a thick wetsuit.
The best of the whole outlook, and I mean the only real standout, is shaping up for the morning of Wednesday the 9th of September. We’ve got an ESE groundswell at 1 ft, but the period is a nice 12 seconds, giving it some shape. The combined energy is moderate (100), and the wind is glassy – absolutely dead calm. That’s the kind of session where you’ll get clean, peeling lines, even if the size is small. It’s a point break setup, so that long period will work in its favour. Crowds are sometimes an issue here, so with conditions this good, expect a few locals out.
Other than that, the afternoon of the 10th of September also offers a glassy window with a tiny 1 ft SE swell, but the energy is weak (57), so it’s a real gamble.
Overall, if you’re willing to sit through a lot of nothing, that Wednesday morning (9th September) is your best bet. The rest of the time, it’s more of a kite-fishing kind of week with the onshore wind and small, messy waves. Stay patient.
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.
