Alright folks, Rusty here. Let’s break down what’s happening at Shida for the next couple of weeks. It’s gonna be a slow start, but there’s a solid stretch of clean surf coming.
Right now, the ocean’s a bit of a mess. Through Wednesday and into the early hours, we’ve got a decent 7ft swell from the SE with a long 16 second period. The combined swell energy is strong (2473). But there’s a cross-onshore breeze messing with the surface, and the water temp is sitting at 72°, which is notably about 4° colder than normal for this time of year. Conditions are marginal, so I’d sit this one out.
But by Thursday morning, the wind switches to a light cross-offshore from the SSE, cleaning everything up. The swell drops a bit to 6ft, still from the SSE with a 14-second period, but energy is still healthy (1626). This kicks off a really good run. Friday gets even better: a light offshore wind from the south, swell bumps back up to 7ft from the S with a powerful 16-second period (energy at 2149). The water is still cold, but the waves are gonna be clean and lined up. This is the best of the bunch.
Saturday holds that same quality: 7ft south swell, 17-second period, gentle offshore breeze. The energy peaks at 2962. This is top-tier stuff. Shida handles this size fine, but with a period over 15 seconds, that long groundswell will produce better shaped waves at this point break, with more power and longer lulls between sets. It’s for experienced surfers, but it’s gonna be a classic weekend. Crowds are often here, so expect company.
Sunday still delivers clean, moderate offshore wind and solid 5-6ft SSW swell. Good, but energy is fading. By Monday the 13th, the swell drops under 3ft, and we hit a flat spell through Tuesday the 14th. Nothing worth paddling for.
The next pulse arrives Wednesday the 15th with 6ft SSE swell at 14 seconds. Light offshore wind, clean again. Thursday the 16th morning holds some clean 6ft SE swell, but the afternoon gets chopped up by a cross-shore breeze. Then from Friday the 17th through Sunday the 19th, the wind turns ugly from the ENE and NE, making for poor, choppy surf. A three-day dry spell for quality.
Now Monday the 20th and Tuesday the 21st are wild. The swell jumps to a massive 13ft from the ESE. That’s way too big for this break. Even Tuesday morning has glassy conditions, but 12ft east swell is for experts only. Later on Tuesday the 21st, the swell drops to a still significant 8ft with a light offshore breeze. That’s a standout for the brave. After that, the forecast gets messy again with onshore wind and poor quality through to the end.
So here’s the takeaway: from this Thursday through Sunday is your window. Clean offshore wind, solid south swell, plenty of energy. The top picks are Friday and Saturday. If you’re experienced, the 8ft clean swell late on Tuesday the 21st is also worth a look. The rest is either flat, choppy, or just too big to handle.
Stay wet,
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.
