Table - best surf conditions forecast for Shichirigahama over the next 16 days.
G'day, Rusty here, and I've gotta be straight with you – the outlook for Shichirigahama over the next couple of weeks is a bit of a tough one. We've got a decent pulse of swell coming in, but the wind is just not playing ball for most of it. The whole period is a bit of a waiting game for a clean session.
The action kicks off this Saturday afternoon, the 11th of July, with a solid 7ft SSW groundswell running at a very long 17 seconds. The combined energy is strong at 2313, so there's plenty of power in the water. But here's the kicker – the wind is howling from the south at 30 km/h, right onshore. It's going to be a choppy, blown-out mess, and honestly, it looks more suited to a kite surfer than a paddle surfer. The water temp is about average for the time of year at 24°.
Sunday the 12th doesn't offer much improvement. The morning still has a decent 6ft SSW swell (16 seconds, energy 1535) but with a light onshore breeze, it's a marginal call at best. The afternoon drops to 5ft and the wind picks up again to a moderate onshore breeze. Not the day for it.
Then we hit a real gem – Monday morning, the 13th of July. The swell drops to 3ft from the SSW (13 seconds, energy 267), but the wind switches to a light glassy offshore from the ENE at just 5 km/h. This is the one standout in the whole forecast. For a couple of hours in the morning, Shichirigahama will be clean, with some fun little waves. It's a river break, so it's inconsistent, but when it's glassy like this, it's the best on offer. The afternoon goes back to onshore slop though.
After that, it's a long, slow grind. From Tuesday the 14th all the way through to Saturday the 25th of July, the swell drops right off and the wind is relentlessly onshore or cross-onshore. Most days have wave energy under 100, with tiny, weak windswell. There's a brief moment on Saturday morning, the 25th of July, with 2ft from the south and a glassy east wind, but the conditions are described as "very ordinary." It's a flicker of hope, but not much else.
The second week is a write-off for quality surf. Small, weak, and onshore. The only real chance to get wet with something decent is that Monday morning session on the 13th. Don't hold your breath for the rest.
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.
