The Lowdown
Right, let’s have a look at what’s on offer for Shida over the next couple of weeks.
To be honest, the first week is a real struggle. There’s some small, weak swell around, but the wind is all over the shop, and the quality just isn’t there. You’ll be staring at a lot of cross-onshore chop and messy conditions. The combined wave energy is weak, barely cracking triple digits for most of it. There’s a brief moment Sunday morning, the 26th, with a glassy 3ft swell from the ENE, but it’s a short-period, weak little windswell (7 seconds) and the break is inconsistent, so don’t get your hopes up. It’s a real waiting game.
The real story here is the second week. A serious pulse of long-period SE groundswell is forecast to roll in, and it gets big. Real big. By Monday the 3rd of August, we’re looking at a 7ft swell from the SE with a 17-second period, and the energy is starting to get proper. That swell builds through the week, hitting 13ft on Tuesday the 4th, and then it just keeps going. By Wednesday the 5th, we’re talking 15ft, and by Friday the 7th, the models are showing a massive 30ft swell from the SE with a 17-second period, with wave energy absolutely massive.
Now, the caveat. Shida is an exposed, inconsistent break. For this spot, once the swell gets over 8ft, it’s expert-only territory. By the time we hit that 13ft mark on Tuesday the 4th, the forecast is literally saying the swell is too big for this break. The wind is also going to be a factor, mostly cross-onshore, which will make it messy and dangerous. The water temperature is currently 79°F, which is bang on average for this time of year.
So, what’s the standout? If you are a very experienced, big-wave surfer, the period from Tuesday the 4th to Thursday the 7th of August is going to be a spectacle. The size and power will be immense. But for the vast majority of us, it’s a no-go. The best realistic surf is probably the brief window on Sunday morning the 26th of July, with those tiny glassy waves, or the small, clean options on the afternoon of Saturday the 1st of August with a 2ft, 10-second SE swell and offshore wind. Honestly, it’s a week of small, ordinary waves followed by a week of colossal, dangerous surf. Kite surfers might be the only ones having fun on the big days.

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.
