Table - best surf conditions forecast for Shida over the next 16 days.
G’day, Rusty here. Look, it’s a bit of a mixed bag for Shida over the next fortnight. There’s a few proper windows of clean, solid swell, but you’ll need to pick your moments. The first week has some real standouts, and there’s a beauty set-up in the second week, but it’s not all good news – there are some choppy, blown-out days in between.
Right out of the gate, Monday 13th July is a cracker. The morning glass-off with a 4ft SSW swell (combined energy of 550), glassy conditions, and a 13-second period will have Shida looking fun and clean. The water temp is about average for the time of year, nothing unusual.
The next few days drop right off. Tuesday 14th and Wednesday 15th are small, weak, and ordinary – not worth a paddle. Then Thursday 16th stays poor.
The real standout of the first week is Friday 17th July. The morning is a nice 3ft SE swell with a 16-second period (combined energy of 622) and gentle offshore wind – clean, long lines. But the afternoon is the pick: 6ft SE swell, 14-second period, and a massive combined energy of 1406. That’s strong, powerful groundswell. The wind is cross-off, so it’ll be clean, but at 6ft, it’s getting solid – better for experienced surfers. For a spot like Shida that’s inconsistent, this is a rare, proper session.
Saturday 18th and Sunday 19th July are a write-off – strong onshore winds and messy, choppy conditions. The swell is big but blown out. Monday 20th is still poor.
Now, the second week has a serious standout. Tuesday 21st July is an absolute gem. The morning is glassy with a 6ft E swell, 12-second period, and combined energy of 1029 – that’s very strong. The afternoon is even better: 6ft E swell, 11-second period, combined energy of 1060, and clean offshore wind. This is excellent, powerful surf, but at 6ft, it’s for the experienced crew. For a break that’s inconsistent, this is a rare gift.
Wednesday 22nd July holds well – 6ft ESE swell, 12-second period (combined energy of 926), and glassy morning conditions. Another very good day, but again, expert territory.
After that, it fades. Thursday 23rd through the end of the month is small, weak, and mostly messy with onshore winds. Sunday 26th July afternoon has a little 2ft SSE swell (combined energy of 211) with offshore wind, but it’s tiny.
So, the best of the best: Friday 17th July afternoon and Tuesday 21st July morning and afternoon. Those are the ones to circle. The rest is mostly a wait.
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.
