The Lowdown
G’day, Rusty here. Let’s get straight into it. The next couple of weeks at Shida are going to be a real mixed bag, and honestly, you’re going to have to be patient. There’s a whole lot of swell on the way, but the wind is going to be a persistent problem for the most part. The real kicker is that when the ocean does settle down, the waves are going to be way too big for this spot. It’s a frustrating outlook, so let’s break it down day by day.
For the first stretch, from Sunday the 2nd through Wednesday the 5th, it’s a write-off. The swell is building from around 4ft up to a massive 13ft, but the wind is blowing a solid cross-onshore at 12 to 19 mph. It’s going to be a lumpy, choppy mess. The wave energy is moderate to strong, climbing from 703 up to a massive 9706, but it’s all for nothing with that wind. You’re just not going to want to be out there; it’s pure frustration.
Then we hit Thursday the 6th and Friday the 7th. The wind drops right off, and the conditions clean up nicely, especially Thursday afternoon with a cross-offshore breeze. But here’s the catch – the swell is still pumping. Thursday morning is 12ft, and by the afternoon it’s 13ft. That is far too big for Shida. The wave energy is strong, sitting between 6912 and 8067. Unless you’re a top-tier expert, this is a no-go. It’s just too dangerous. Friday sees the swell back off a touch to 10ft in the morning, but still way oversize. The afternoon drops to 8ft, but the wind swings cross-shore and it gets messy.
The weekend, Saturday the 8th and Sunday the 9th, brings the swell down to a more manageable size, but the quality drops off. Saturday has 7ft to 7ft waves with a clean cross-offshore wind, but the forecast comments say it’s marginal and the energy is moderate at 2806 and 2754. It might be rideable for the brave, but it’s not going to be spectacular. Sunday the 9th is worse, with the swell dropping to 5ft and the wind turning cross-onshore again, making it choppy. It just doesn’t come together.
From Monday the 10th right through to the end of the period on Monday the 17th, it’s a long stretch of poor conditions. The wind stays strong and onshore or cross-onshore for most of it, and there’s another big pulse of swell mid-week. The 14th, for example, shows 15ft waves with a strong cross-shore wind and messy conditions. The energy is huge, climbing to 6943, but it’s all for nothing. It’s a long, blank run.
So, what’s the verdict? To be honest, there isn't a standout session in this entire window. The one small glimmer was supposed to be Saturday the 8th, but it’s just not good enough. With the water temp at 80°, which is totally normal for this time of year, the ocean is warm, but that’s about all it has going for it. This stretch of weather looks more interesting for the kite surfers than the paddle surfers, to be honest. The swell is there, but the wind is just never your friend. Hang tight, this kind of run doesn’t usually last forever. This is Rusty, signing off.

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.
