Righto, listen up. Let’s talk about Shichirigahama.

Straight up, this is a tough forecast. The first few days are a write-off for anything decent. You’ve got a solid pulse of Southern Ocean energy rolling in on the 10th and 11th—swell heights around 5ft to 7ft, with a long period 15-17 seconds and a combined energy reading that’s up there (2368 on the Saturday morning). That’s proper groundswell. But the wind is howling from the south and south-southwest, straight onshore, and it’s just destroying the surface. The water is sitting at 75°F which is a bit colder than usual for this time of year, so you might want a spring suit for comfort.

The first real glimmer of hope comes on Sunday morning, July 12th. The swell drops a touch to 6ft, still from the SSW with a 16-second period, and the energy is still strong (1386). But the key change is the wind: a light northwesterly, 3 mph, blowing cross-offshore. That’s going to clean the face right up. The wave comment says it’s excellent for experienced surfers. At 6ft, it’s a bit punchy for beginners, but for the crew who know what they’re doing, Sunday morning is the standout. The crowd factor is “sometimes” here, so you might have a few others in the water, but with that quality, it’s worth it just be aware it’s a river mouth setup, so the long period swell might make it a bit straight at times, but the offshore wind will help.

After that, it’s a slow fade. Monday the 13th sees the swell drop to 3ft with a 12-second period, and the wind is offshore from the north at 6 mph. The surf is clean but small—just ordinary surfable waves. Tuesday the 14th morning is glassy, with 2ft of swell and a 11-second period, but the energy is low (102). From there, the swell just dies off. We get a string of tiny, onshore days from the 15th through to the 23rd. The winds are from the south and southeast, mostly onshore or cross-onshore, and the swell is barely scraping 1ft to 2ft. There’s a period around the 15th where the swell jumps to 4ft, but with a 5-second period and moderate onshore wind, it’s just bumpy junk.

The second week is a long run of poor conditions. The 24th and 25th of July show a little flicker of life: a 2ft to 3ft SSW swell with a 12-second period, and a decent 16 mph north-northeasterly offshore wind on the 24th morning and 25th morning. The energy is moderate (140-223), and the conditions are clean. But it’s still small. The 24th morning is the best of that late run, but it’s not a classic.

Overall, the one true standout is Sunday morning, July 12th. That’s your window. After that, it’s a 10-day gap with nothing worth paddling out for until the 24th, but even then it’s small. Forecasts can change, but right now, it’s a waiting game.

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.
