The Lowdown

Alright, let’s get into it. The next couple of weeks are a mixed bag, and we’re looking at a bit of a slow start before things get interesting. First up, we’ve got Shida. It’s an exposed spot, and the swell direction is playing around, but the main story is a chunk of clean, cross-off swell right at the start, and then a couple of big pulses that might just be too much for this place.

Thursday morning starts things off with a 7ft SSE swell at 13 seconds, but the wind is cross-onshore and it’s looking choppy. Not great. The afternoon is a different story though – same height, 12 seconds, but the wind swings cross-off and it cleans right up. This is the first real window, and with a light breeze, it’s worth a paddle. The energy is moderate, at 1776.

Friday follows that up with a solid 6ft S swell at 13 seconds, and it’s clean with a cross-off breeze in the morning. There’s a risk of a thunderstorm, but if you can dodge the rain, the surf will be good for the more experienced crew. The energy dips slightly to 1452 in the morning, but it’s still got some push.

Saturday is a bit smaller, 5ft, but the period stays at 12-13 seconds. The morning is clean, and the afternoon sees the swell direction shift to ESE, bumping the energy up a notch to 1148. It’s a fun, user-friendly day, but not the standout.

Sunday is where things start to get messy. The swell is 6ft ESE, but the wind goes cross-on and then cross-shore, putting a chop on it. The energy is still there, 1557 in the morning, but the quality drops off fast. This is a skip.

Monday is a write-off. The wind is howling from the NE at 19-22 mph, making it lumpy and poor. The swell is there, 5-7ft, but it’s not surfable. Don’t even bother.

Now, here’s where it gets real. Tuesday the 11th of August. The swell jumps to 10ft, then 12ft from the NE. The energy is strong, 3146 in the morning, 4591 in the afternoon. The wind is favorable, but the comment is clear: it’s too big for this break. This is expert-only territory, and even then, it might be closing out. For the average surfer, this is a day to watch from the beach. It’s big, powerful, and intimidating.

After that pulse, Wednesday the 12th drops back down. Morning has a clean 4ft ESE swell with a 17-second period – that’s proper groundswell, and it’s glassy with a light cross-off. The energy is 2205, which is moderate, and this is a real standout for the period. The long period means it’ll be lining up better at a point or reef, but for Shida, a beach break, it might be a bit too straight. Still, the conditions are there. The afternoon, however, jumps back up to a 10ft E swell, and it’s too big again.

Thursday the 13th looks poor, with onshore winds and messy waves. The swell drops a bit on Friday the 14th, and the afternoon session is the one to grab – 8ft E swell, 11 seconds, clean with a cross-off breeze. Energy is moderate at 1265. That’s a solid afternoon.

The weekend and the days after are mostly small and messy. The swell drops to 4ft and below, with periods dropping to 9-10 seconds. Winds are mostly cross-on or onshore, often fresh, making it choppy. Energy readings are weak, dropping below 500. This is a flat spell, and it looks like it’ll last a few days. There’s a slight pulse on the 20th of August, bringing 6ft ENE swell, but the wind is howling onshore again. Not good.

So, the true standouts here are Thursday afternoon, Friday morning, and that Wednesday the 12th morning session. If you’re paddling out, make those windows count. The rest is either too big, too messy, or just too small.

Don’t forget the water is about average for this time of year, nothing crazy going on there. And remember, this is Shida – it’s inconsistent, so when it’s on, it’s on, but it can also be a no-show for a while. This forecast is a prime example of that.

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.
