Alright folks, Rusty here. Let’s take a look at what’s brewing for Shida over the next couple of weeks.
We’ve got a solid run of surf coming up, but you’ve got to be patient. The first few days are a bit of a write-off, but from Wednesday afternoon onward, it really starts to fire. The standout window is from Thursday the 10th through Saturday the 12th, and then again on Sunday the 19th. There’s a bit of a lull in the middle of the second week, but the bigger stuff returns for the final weekend.
The water temperature is sitting at 72°, which is much colder than normal for this time of year – a solid 4° below the average. It’s a noticeable chill, so you’ll want a thicker wetsuit.
Right, let’s get into it. Things start off messy. Tuesday the 7th morning is a no-go: a 5ft SE swell, but with a cross-on wind and only 921 (weak) combined energy. It’s just choppy and poor. Tuesday afternoon improves a little to 5ft, but the cross-shore wind still has a chop on it.
Wednesday the 8th morning is a bit of a tease. The swell is pushing 7ft from the SE, with a long 16-second period, giving it 2473 (moderate) energy, but the wind is cross-shore, leaving it lumpy. Wednesday afternoon is where it turns on. The swell drops slightly to 7ft, but the direction shifts to SSE and the wind goes cross-offshore. The energy is still high at 2282, and it’s clean. This is the start of the good stuff.
Thursday the 9th is a beauty. Morning sees a 6ft SSE swell with a 14-second period, light offshore wind, and 1594 (moderate) energy. It’s clean. The afternoon stays clean with 5ft and a gentle offshore breeze. This is proper, shapey groundswell for experienced surfers.
Friday the 10th and Saturday the 11th are the real highlights of the first week. Friday morning kicks off with 7ft from the S, 15-second period, light offshore wind, and 1939 (moderate) energy. Clean as a whistle. Friday afternoon jumps to 7ft, 16-second period, 2556 (strong) energy, and a moderate offshore wind. This is powerful, lined-up surf. Saturday holds steady with 7ft, 16-second period, and offshore winds all day. The energy is strong at over 2400. This is the best on offer for the first week – big, clean, and consistent, but at 7ft, it’s for experienced surfers only.
Sunday the 12th starts to drop off. Morning is 5ft with a cross-offshore wind, still clean, but the energy drops to 1243. Afternoon gets stronger wind at 25 mph, and the swell drops to 5ft. It’s still clean, but the power is fading.
Then we hit a quiet patch. From Monday the 13th through Wednesday the 15th, the swell drops to under 4ft. The wind is offshore, keeping it tidy, but the energy is very low (under 500). You’d be on a longboard or a foiler, if anything. This gap of low-energy surf lasts about 4 or 5 days.
Thursday the 16th morning sees a little bump, with a 5ft ESE swell, 11-second period, light offshore wind, and 500 (weak) energy. It’s clean, but nothing special.
Sunday the 19th is the second standout. The morning brings a solid 8ft S swell, 14-second period, with a gentle offshore wind and a massive 3196 (strong) combined energy. The afternoon is 7ft, 13-second period, and 2792 (strong) energy. This is powerful, clean, and for experienced surfers. It’s the best looking day in the second week.
Monday the 20th morning has a 10ft swell from the E, but that’s predicted to be too big for this break. The afternoon drops to 8ft, which is still a big, powerful wave for experts only. After that, the swell fades again through the 22nd.
So, to sum it up: hit the first week from Wednesday afternoon through Saturday, with Thursday, Friday, and Saturday being the standouts. In the second week, keep your eyes on Sunday the 19th for the next big swell.
Stay safe out there.
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.
