Table - best surf conditions forecast for Shichirigahama over the next 16 days.
Hey, Rusty here with the scoop for your local stretch. Shichirigahama – that river mouth break – is a fickle one, inconsistent and draws a crowd when it works. Here's the 16‑day outlook.
Best shot is Wednesday morning, July 8th. Waves around 5 ft from the SSE, with a long 16‑second period – proper groundswell that'll wrap nicely into the river mouth. Wind is light cross‑off from the east at 6 mph, keeping things clean and glassy. Combined swell energy is moderate (1094). Water temp is 75°F, just about normal for mid‑summer. That morning is the clear standout.
Then the wind swings onshore, and the quality drops fast. From Wednesday afternoon through the whole first week, it's mostly side‑to onshore winds and poor conditions. There's a brief moment on the 15th and 16th with some small, ordinary waves, but nothing worth paddling out for. The swell fades to ankle‑biters by July 13th.
Into the second week, look for a new pulse around Wednesday, July 22nd. Offshore NE wind at 12–15 mph, clean 4–4 ft swell from the south with a 14‑second period. That afternoon and the following morning (Thursday 23rd) bring good, clean waves – small but well‑shaped. It's a promising window, though far out.
So if you want the best, be on the water Wednesday morning, July 8th. After that, patience is key – the second week offers a late chance, but no guarantees. Keep an eye on the wind forecasts.
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.
