The Lowdown
Alright, Rusty here. Let’s talk about the surf for this region over the next couple of weeks. It’s a quiet spell for the most part, but we’ll get a few brief windows where it comes alive.
The first real interest comes on Tuesday the 14th of July. We’ve got tiny 2ft swell pushing in from the south with a 10-second period. The combined energy is weak at 132, so it won’t have much punch. The water temp is sitting at 76°, which is about normal for this time of year. It’s clean with a light offshore breeze, but honestly, it’s pretty ordinary.
Wednesday the 15th and Thursday the 16th stay small, with the swell dropping to 2ft and then lifting slightly to 3ft. The wind is offshore and clean, but the energy is still in the weak range (75 to 117). Not much to get excited about.
Now, Friday the 17th is where we get a little more size. The morning shows a bump to 4ft from the ESE with a 9-second period. The combined energy climbs to 200, which is moderate. It’s clean with a light breeze, and conditions are shaping up decently. This is probably the best bet in the first week, but still not a standout.
The weekend runs into a bit of a lull. Saturday the 18th has small 3-3ft swell with improving energy on the afternoon (207), and clean conditions. But Sunday the 19th and Monday the 20th are flat and poor with light cross-shore breezes. The energy stays in the 150-159 range, and the waves are just messy.
We get a brief respite on Tuesday the 21st morning with glassy conditions and 3ft swell from the east. The energy is 146, so it’s clean but small. Wednesday the 22nd keeps the same small size with offshore wind and a little more energy (182) in the afternoon.
From Thursday the 23rd onward, the wind starts turning strong. Swell stays small around 2-3ft, but we see gusty SW winds hitting 19 mph. The combined energy climbs a bit (168-259), but the wind is ruining it. The setups are getting blown out, and honestly, it starts looking more interesting for kite surfing than paddle surfing. The water gets choppy and messy through to the end of July.
Then, on Tuesday the 29th of July, we see a spike in the data. The morning shows 4ft swell from the SE with a long 13-second period. The combined energy jumps to 560, which is strong wave energy. The wind is light and cross-shore, but the afternoon cleans up with a cross-off breeze. This is the only real standout of the whole outlook — a powerful groundswell with good period, but it’s at the very end of the forecast window, so treat it as promising but less certain. For a spot like Shida, this long-period SE swell could line up nicely if the sets find the right bank. The size is manageable for intermediates, not too big.
Summing it up: the next couple of weeks are mostly small and average, with a brief decent window on Friday the 17th and a hopeful pulse at the very end on the 29th. If you’re keen, keep an eye on that last one, but don’t hold your breath for the rest.
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.
