The Lowdown
Alright, surfers, Rusty here. Let me break it down for you.
The next 16 days at Shida are a real mixed bag. We’ve got a long, quiet patch to start, then a solid pulse of energy shows up, but it comes with a massive dose of size that’ll only be for the brave. We’re looking at a pretty flat start, so don’t be in a rush.
The first few days out of the gate are poor. Saturday the 25th is a no-go with a risk of thunderstorms, a messy cross-shore wind, and only 1ft of weak, long-period swell (143) that won’t do a thing. Sunday the 26th shows a slight flicker of hope. The morning is still junk with a short-period 4ft wave from the NE, but Sunday afternoon is our first real glimmer. We get a clean 3ft wave from the ENE with a light offshore wind. It’s small, but it’s surfable. Monday the 27th through the end of the month is mostly a write-off – onshore winds, choppy conditions, and tiny waves. The water temp is sitting around 78°, which is about normal for this time of year, so no surprises there.
We then hit a big gap. From the 27th of July all the way through until the 7th of August, there’s almost nothing worth paddling out for. You’ve got some glassy mornings on the 1st of August but with only 1ft on offer, it’s barely a ripple.
Now, here is where it gets interesting. A massive long-period groundswell from the ESE builds in from the 3rd of August, but it’s way too much. The combined energy goes from 1070 to over 5000, with wave heights climbing from 5ft up to a solid 12ft. The problem is, the wind is cross-on and choppy the whole time, and the sheer size will make it a washing machine. For beginners, anything over 5ft is a handful; this is pushing expert territory. The forecast actually says it’s too big for this break on the 5th and 6th, and I agree. It’s more of a kite-surfing show than a paddle session.
The real standout, the one to circle on your calendar, is Friday the 7th of August. The swell drops back to a much more manageable 6ft from the ENE, with a clean offshore wind from the SSW. The combined energy is still a healthy 962, and the conditions are described as “very good.” This is your window. It’s a solid, lined-up swell with good wind. The next day, Saturday the 8th, is also excellent. The swell swings around to the SSW, with a very long 16-second period, and it’s a clean 5ft. For experienced surfers, Sunday the 9th could be the pick of the bunch, with a glassy 6ft SSW groundswell and a massive energy reading of 2301. The long period means it’ll have plenty of push, but at a beach break it could be a bit straight. It’s one for the reef or point if you can find it, but it’s a thrilling prospect.

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.
