Table - best surf conditions forecast for Shida over the next 16 days.
Alright folks, Rusty here. Let's have a look at what Mother Nature's got on the menu for us. We're focusing on one spot for the next couple of weeks, and to be honest, it's a bit of a slow burn.
The first few days are a mixed bag. We've got a solid pulse of groundswell rolling in on Saturday the 11th, but it's a bit of a specialist affair. Shida picks up a 6.9ft S swell with a long 16-second period, packing a hefty 2508 combined energy. That's a lot of water moving, but with that length, it can tend to close out here. It's an inconsistent break at the best of times, so you need to be patient. Saturday afternoon looks clean enough with a moderate offshore breeze, but the size and power mean this is really for experienced surfers only. Water temps are sitting at 74.5°, which is a touch colder than we'd normally expect for this time of year; grab a decent spring suit.
Sunday the 12th stays chunky with 6.2ft dropping to 5.9ft, but the wind turns cross-off, making things a bit trickier to read. The energy is still strong, but the quality dips. From Monday the 13th through to Thursday the 17th, we go quiet. Real quiet. Expect a few days of small, weak surf—mostly under 3.3ft with short, weak periods and pretty ordinary conditions. If you’re desperate, there's a tiny window Monday afternoon with 3.3ft and glassy conditions, but it's not worth paddling out for.
The Standout Options
The real standout for the whole run is Saturday the 11th. That's your best bet. A solid 6.9ft S swell, long period, and offshore wind. It's going to be powerful, so bring your big-wave board and your best paddle fitness. Crowds are likely here as it's the best thing on offer, so get there early. Just remember it's inconsistent, so don't get frustrated between sets.
Looking further ahead, keep an eye on Wednesday the 22nd of July. The models are hinting at a nice 5.6ft SE swell with a 12-second period and a clean offshore breeze. The combined energy is a solid 988, which is promising. It's a long way out so treat it as a promising whisper rather than a roar, but it could be the best clean, manageable swell we see outside of the first weekend. For the second week, things stay small and ordinary with onshore or cross-shore winds, but that 22nd stands out.
Overall, it's not going to be a classic fortnight. There's one solid but challenging day for the experienced crew, and a potential gem two weeks out. The inconsistent nature of Shida makes the flat spells feel longer, but that's just how it is here sometimes.

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.
