The Lowdown
Alright folks, Rusty here. Let’s break down the next couple of weeks for Shichirigahama.
First thing you need to know – this river break is inconsistent at the best of times, and for the first week it’s pretty much a write-off. From Sunday 19 July right through to Sunday 26 July, we’re looking at tiny waves, poor conditions, and nothing worth paddling out for. The wind is mostly onshore or cross-onshore, swell heights barely crack 2 ft, and the combined energy is weak. It’s a flat spell, so don’t bother checking the cam.
Then things change. On Monday 27 July, a solid groundswell arrives. The morning brings a 5 ft SSE swell with a 14-second period and gentle offshore wind from the NNE – clean, lined up, and with moderate energy. That’s the first real window. The afternoon steps it up to 6 ft SSE, 15-second period, light cross-offshore breeze, and the energy jumps to moderate-to-strong. This is proper surf for intermediate and above. The break is a river, so that long-period groundswell will wrap in nicely and hold its shape.
Tuesday 28 July morning is even better if you’ve got the skills – 8 ft SSE swell, 15-second period, glassy conditions with a light ESE breeze, and strong energy. That’s expert territory, but the waves will be clean and powerful. The afternoon turns ugly with 10 ft but onshore S wind at 12 mph, making it a mess – pass on that.
The standout? Wednesday 29 July morning. 13 ft SSE swell, 16-second period, glassy, and the combined energy is very strong. This is exceptional for expert surfers only. The river mouth will handle that long-period groundswell well, but it’s going to be big and heavy. If you’re not confident, stay on the sand. The afternoon gets ruined by onshore wind again.
After that, the swell drops fast. Thursday 30 July to Monday 3 August is back to small, poor conditions with onshore or cross-onshore wind and weak energy. There’s a brief chance on Saturday 1 August morning with 3 ft SSW swell, glassy, but it’s only “surfable” – not worth chasing.
So the takeaway: the first week is dead, then a solid 3–4 day window from 27 July to 29 July morning. The best of the best is Wednesday 29 July morning – get it early, it’ll be epic but only for the brave. Expect crowds to be possible at this spot, especially when it’s good.
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.
