Alright, Rusty here. Let’s have a look at what’s coming up for Shida over the next couple of weeks.
We’ve got a decent pulse of swell arriving this Saturday, July 11th, and that’s where the real action is. The water is sitting at 74°, which is a bit colder than normal for this time of year – about 2° off, so you’ll notice it’s a touch cooler than usual if you’re used to swimming here.
Saturday morning, July 11th, sees a solid 7ft south swell rolling in with a very long 16-second period. That’s proper groundswell energy, and the combined energy is a hefty 2691, which is strong. The wind is a cross-off from the SSW at 9 mph, so the waves will be clean with some shape. This is a bit much for beginners – over 5ft – but for experienced surfers, it’s a standout. The afternoon picks up with offshore winds at 16 mph, making for excellent conditions, though still a sizable 7ft. The swell direction from the south is right in the sweet spot for Shida’s exposed setup. Crowds are often around here, so expect company.
Sunday, July 12th, drops a touch to 6ft in the morning and 5ft in the afternoon, still with that long 16-second period, but the wind swings cross-off from the SW. It’s surfable, but not as crisp as Saturday. The energy drops to 1820 then 1344 – still moderate to strong, but the quality is more marginal.
Monday, July 13th, sees a big drop. The swell fades to 3ft by morning with a 13-second period, but the wind is onshore from the NNW at 6 mph, so it’s poor. The afternoon brings a brief window of glassy conditions with a light NNE breeze at 3 mph and 3ft swell, but the energy is only 296 – weak. Not worth paddling out for.
From Tuesday, July 14th, through to Friday, July 17th, it’s a real lull. Swell hangs around 2ft to 3ft, with short periods (8–10 seconds) and weak energy under 200. Winds are mostly offshore or cross-off, so the surface is clean, but there’s barely any wave to ride. These are days for a coffee and a walk on the beach.
Saturday, July 18th, and Sunday, July 19th, stay small – 2ft and 2ft, with energy dropping below 100 on Sunday. The wind is offshore, but the swell is too weak to get excited about.
Monday, July 20th, shows a tiny bump to 3ft–3ft with a 9-second period, but the wind shifts cross-off from the ESE. Still, energy is only 160–189, so it’s ordinary.
Then we hit a rough patch from Tuesday, July 21st, onward. The wind turns cross-onshore and fresh, with speeds up to 19–22 mph. The swell does build again – Tuesday afternoon sees a 3ft swell with a very long 18-second period, energy 675, but the wind is messy. Wednesday, July 22nd, brings 7ft swell with a 12-second period and strong energy (1621), but the cross-onshore and lumpy conditions make it a write-off for paddle surfing. This setup looks more interesting for kite surfing than a traditional surf session. That pattern continues through to the end of the month – decent swell heights but blown out by strong onshore winds.
So, to wrap it up: your best bet by a long shot is Saturday, July 11th. That’s the standout. The south swell, long period, and offshore winds at Shida will give you clean, powerful waves. Sunday is a second option but not as clean. After that, the window closes for a good week, and then the wind ruins any potential from the bigger swells later on.
Stay tuned, but for now, make the most of that Saturday.
Rusty.

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.
