The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Shida over the next couple of weeks.
Right off the bat, we gotta be patient. The first few days are a bit of a write-off, with small, weak swell and ordinary conditions. The good stuff doesn't really kick in until Sunday the 2nd of August. That's when the ocean starts to wake up.
The standout window is Sunday the 2nd through Monday the 3rd of August. Sunday morning sees a clean 4ft SE groundswell with a long 14-second period rolling in, and light offshore breezes. The combined energy will be solid (587-623). It's building, and conditions are looking really clean. Then Monday the 3rd is the absolute pick of the 16 days. We're looking at a clean 6ft to 7ft SE groundswell pushing in with a 15-16 second period. The energy jumps right up (1328-2224), and with light winds and that clean, glassy feel, this is prime time. The swell is over 5ft, so it's a bit much for the groms, but for the experienced crew, this is gonna be magic.
After that, things get wild. From Tuesday the 4th, the swell just keeps building, hitting 10ft, then 18ft, and even 20ft by Thursday the 6th. The combined energy is massive (over 6000 to 18000+). But here's the catch – the wind is cross-onshore, and the report says the swell is predicted to be too big for this break. We're looking at a serious, straight-up messy and dangerous situation. The set-up looks more interesting for kite surfing than paddle surfing. This is strictly for experts only, and even then, it's a big call.
The size drops back by Saturday the 8th of August, with a 7ft S swell and clean cross-offshore winds, but it's still a solid 7ft, so it's not for the faint-hearted.
The final week fades out. The swell drops to 4ft to 5ft, but the winds are mostly cross or cross-onshore, and the energy drops off. The last few days from the 10th to the 12th look pretty poor with messy, choppy conditions.
So, to wrap it up: if you can get out on Sunday the 2nd or Monday the 3rd of August, you'll be laughing. The rest of the window is either too small, too messy, or too big. Keep your eyes on that Sunday-Monday window.
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.
