The Lowdown
Alright folks, Rusty here. Let’s take a good hard look at what’s coming up for Shichirigahama. I’ll be straight with you – this is a tough read, and it’s going to take a while for things to get interesting.
Right off the bat, we’ve got a long stretch of nothing. From Thursday the 23rd right through to the end of the month, the waves are tiny, messy, and just not worth paddling out for. The water is sitting at about 81°, which is a touch warmer than normal for this time of year, but that’s about the only nice thing I can say. The wind is all over the place, mostly onshore or cross-off, and the swell is barely a ripple. It’s a proper blank run.
We finally see a flicker of life on August 3rd, Monday morning. The combined energy jumps to 445 (moderate), with a solid 3ft swell from the ESE, and a period of 18 seconds – that’s a proper groundswell. But here’s the kicker: the wind is onshore from the SSW, so it’s going to be bumpy. The report calls it “marginal” at best, and honestly, for a river mouth break like this, that long period might make it a bit too straight and fast. It’s not a day for beginners, that’s for sure.
The swell hangs around through Tuesday the 4th (energy 320), but again, onshore wind keeps it from being clean. It’s not until the very end of the forecast, on Friday August 7th morning, that we get a glimmer of hope. The wind is glassy, calm, and the swell is 3ft from the SSW – but with a period of only 4 seconds, it’s short-period windswell, not a groundswell. By the afternoon, the wind turns cross-onshore and the swell jumps to 6ft, but the energy is high (243) and it’s going to be a choppy, blown-out mess.
Honestly, for the whole 16-day window, there’s no standout session. The best you’ll get is a gamble on the morning of August 3rd if you’re an experienced surfer who can handle onshore conditions. The setup is more interesting for kite surfing than paddle surfing on those bigger, wind-affected days.
Keep your eyes on the forecasts, though. It tends not to stay this poor for long.
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.
