The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the cards for the Shida stretch. It’s gonna be a tale of two extremes: a whole lot of nothing at the start, then a massive pulse of swell that’s too much of a good thing.
It’s a quiet start. We’re looking at a long, flat spell right through the first week. From Sunday the 26th of July, right through to Saturday the 1st of August, the surf is just not there. It’s all small, weak, and messy. The wind is mostly cross or onshore, and the swell is tiny and inconsistent. You’re basically looking at a week of nothing worth paddling out for. The energy is low, and it’s a bit of a bummer.
Things finally start to show a pulse on Monday the 3rd of August. But it’s a tricky one. The swell starts to build, coming from the SE with a very long period of 15-16 seconds. That’s a proper groundswell, but the problem is the wind. It’s coming from the NE, which is a cross-on breeze at Shida. The swell height climbs from 5ft to 8ft through the week, but it’s going to be a choppy, bumpy mess. The combined energy is massive – we’re talking four and five-digit numbers (1099 to 3637) – but the quality is shot by the wind. The period is long, so it’ll be better suited to a point or reef break, but here at Shida, it’s going to be a lot of closeout sections.
The standouts? Honestly, there’s only one period that’s even close to being worth a look. If you’re an experienced surfer, keep an eye on Monday the 10th of August. The wind finally swings offshore (SSW) and the swell is still solid at 6ft to 7ft from the ESE with a 14-second period. The combined energy is still very strong (3575 and 2843), but with that clean offshore wind, it’s the only time in the whole forecast that looks proper. The guidance says it’s for experienced surfers, and that’s dead right. It’s still a big swell, and with that long period, it’ll be pitching. But for a skilled surfer, that Monday is your window.
The days before that, from Thursday the 6th to Sunday the 9th of August, the swell is just too big and the wind is all wrong. The forecast is calling for 13ft to 20ft swell with strong cross-onshore winds. That’s a washing machine. It’s more of a kite-surfing setup than a paddling one.
So, to wrap it up: the first week is a total write-off. The second week has a massive swell, but it’s mostly blown out. The only pocket of quality is that Monday the 10th of August with clean offshore winds, but it’s not for the faint-hearted. The water temperature is sitting at 78°F which is right on the money for this time of year, so at least you won’t be cold while you’re getting turned inside out.
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.
