The Lowdown

Alright, folks. Rusty here. Let’s break down the next couple of weeks at Shida. It’s a slow start, but there’s a couple of sessions that are gonna be worth the wait.

Right now, Wednesday morning, the 26th of August, is the best you’re gonna get for a while. We’ve got a clean 4ft swell from the south, with a light cross-offshore breeze. The water is sitting at 82°, which is a touch warmer than normal for this time of year. The combined energy is a solid moderate 475. It’s not huge, but it’s clean, and there’s some push to it. Remember, Shida is an inconsistent spot and can get crowded, so don’t sleep on that Wednesday morning session.

After that, it goes quiet. Thursday and Friday offer small, marginal waves, but the wind stays messy or the conditions are just not cooperating. Saturday the 29th through to Monday the 31st is pretty much a washout—small, choppy, and cross-onshore. You’re looking at a dry spell of about four to five days with nothing worth paddling out for.

Then it starts to turn. Tuesday the 1st of September is still small and a bit weak, but the wind is light. Not a standout, but it’s a sign of life.

Now, here’s the one to circle. Wednesday the 2nd of September. Morning and afternoon both have a proper 4ft swell from the SSW, with a very long period of 15 seconds. That’s groundswell, that’s power. The wind is offshore and clean. The combined energy is huge—1144 to 1200—so this is strong stuff. The wave quality is high, but the swell height is moderate, so it’s not just for the experts. That said, with that long period, it’s gonna be better for a point or reef than a beach break, as it might close out. Still, this is the best on offer in the whole outlook. Get on it.

Thursday the 3rd of September is still clean with moderate cross-offshore winds and a 4ft to 3ft SSW swell, but the energy is backing off a bit. Still a good follow-up day.

Friday the 4th and Saturday the 5th morning are a mess again with rain and cross-onshore wind. But Saturday afternoon, the 5th of September, is a sneaky little gem. The wind goes glassy, the swell bumps to 5ft from the ENE, and it’s clean. The period is short at 8 seconds, so it won’t have the grunt of a groundswell, but glassy conditions are pure gold.

Sunday the 6th of September stays clean with a 5ft easterly swell, but the period is still short. Not bad, but not a standout.

Then we get to the big one. Monday the 7th of September morning and afternoon sees a 8ft south swell with a 14-second period and combined energy over 2000. That’s serious power. The wind is cross-offshore, so it’s clean, but at 8ft, this is expert territory. This is a big, powerful, long-period groundswell. It’s gonna be a beast, and it’s only for the experienced crew. Tuesday the 8th of September is still pumping with a 7ft south swell, offshore wind, and excellent conditions. Another one for the experts.

After that, the swell backs off through the 9th and 10th, with variable winds and dropping energy. The second week has a couple of real heavy hitters for the strong swimmers, but the consistency is not there for the average surfer.

If you’ve got the skills and the timing, lock in Wednesday the 2nd of September for the best mix of size, quality, and clean conditions. The 7th and 8th are for the big-wave chargers only.

Rusty, out.

Information about the Shida Surf forecast

The above surf forecast table for Shida provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Shida can be found by selecting the local surf guide option on the grey menu. Our Shida 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 (Shida) 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 Shida 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.

Shida is 9 km (6 miles) from the city of Ohara. If you plan a holiday in Chiba, look for hotels and other accommodation in Ohara. Ohara has rooms for a wide range of budgets as well as car hire and transport links.
