The Lowdown
Alright, Rusty here. Let's have a look at what's coming our way.
First up, it's a grim start. We're looking at a solid week of flat, poor conditions around Shichigahama from Monday the 20th through to Sunday the 26th of July. Nothing doing. The waves are tiny, energy is weak, and the wind is either onshore or cross-off, but frankly, there's no swell to work with anyway. It's a dead period.
Things start to stir on Monday the 27th of July. We get a morning pulse of S swell at 2ft, period 12 seconds, and a decent jump in energy. The wind is a clean cross-off from the NE, so it's rideable, but very ordinary. Don't get too excited yet.
The real standout arrives on Tuesday the 28th of July. The morning is the pick of the entire forecast. A clean 4ft S swell with a 13-second period hits the river mouth at Shichirigahama. The energy is solid, and with a light E breeze keeping it cross-off, the conditions are expected to be very good. This is a proper groundswell, and with that longer period, the waves will have shape and power. It's not too big, so it's a good one for strong intermediates as well. The water temp is about average for this time of year, so no surprises there.
The Wednesday morning (29th of July) is also worth a mention. The swell builds slightly to 5ft, still from the SSW, with a 13-second period and solid energy. The wind again is light and cross-off from the E. It's a touch bigger, so the river mouth will be working nicely. This is the second best window.
After that, things get messy. From Thursday the 30th through to the end of the forecast, the wind swings onshore and strengthens, ruining the surf. The swell sticks around, but it's blown out. By the time we get into August, the wind is howling from the S at 25 mph, and the waves are just a choppy mess. Not worth paddling out for.
So, to sum it up: the first week is a write-off. The window from Tuesday the 28th to Wednesday the 29th of July is your only real chance. Get on the Tuesday morning if you can – that's the cleanest, most promising surf we've got.
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.
