The Lowdown

Alright, grab a coffee and settle in, because I’m Rusty, and here’s the long-range look at Shida.

Alright, listen. Shida’s the only game in town on the cards for this whole 16-day window, and it’s a classic case of a spot that’s fussy. It’s inconsistent by nature, so you’ve gotta be patient. The water’s warm, sitting at 81°F with a slight anomaly – about 2°F warmer than usual for this time of year, so you can leave the 4/3 at home.

We kick off on Saturday, 5th September, but honestly, don’t bother paddling out. It’s a small 3ft swell from the ENE with a weak 5-second period, and a cross-on breeze is making it choppy. The energy is pathetic (105). It’s a write-off.

Sunday, 6th September, sees a jump in size to 6ft from the E, but the wind is howling from the NE at 19 mph, cross-on and lumpy. The energy ticks up to 332, but it’s ugly. By afternoon, it’s 7ft and still messy. Skip it.

Now, Monday, 7th September, is where it gets interesting, but it’s a real trap. The swell surges to 12ft from the SE with a solid 8-second period, and the energy is massive (1935). The wind switches to a clean cross-off, but the problem is that 12ft is too big for this break. It’s a shallow, exposed spot, and that’s expert-only territory. The afternoon sees 13ft from the S with a 10-second period and a strong offshore wind – clean, but near-impossible to paddle into (3327 energy). Stay on the beach unless you’re a pro and you know the reef.

Tuesday, 8th September, morning is still big at 10ft from the S, but the wind is cross-off and clean. Energy is still bonkers (3601). Again, too big for the average punter. The afternoon drops to 8ft from the SSE with a 10-second period, and the wind is light and cross-off. This is the first real window for a confident surfer. The energy is moderate (938), and it’s clean. This is your best bet if you’re intermediate and can handle a bit of punch.

Wednesday, 9th September, shows 7ft from the S with an offshore wind in the morning, but the period drops to 8 seconds, which is a bit short and crumbly. The energy is moderate (580). The tide might be questionable, but it’s surfable.

From Thursday, 10th September, through to the end of the first week, it’s a total bust. The wind swings onshore and the swell drops, with energy readings under 700. Choppy, lumpy, and messy. Don’t waste your time.

Now, looking at the second week, things get weird. Saturday, 12th September, throws up a tiny 2ft swell from the E, but with a very long 14-second period – that’s proper groundswell energy. The wind is glassy, near-offshore. The energy is weak (260), but that long period means it’ll push through at the river mouth or reef. It’s small, but it could be clean and fun on a longboard. The same goes for Saturday afternoon, with a light offshore breeze (227).

Sunday, 13th September, and into the next week, the wind turns back onshore from the NE, and the swell stays small (2ft to 4ft). The period is long (9-13 seconds), but the cross-on chop ruins it. The energy stays below 500. It’s not worth it.

The very end of the window, Saturday, 19th September, and Sunday, 20th September, shows tiny 2ft to 2ft swells with clean offshore or cross-off winds, but the energy is pathetic (under 100). You’d be surfing waist-high mush at best.

So, the standout. The absolute best on offer is Tuesday, 8th September, afternoon. That 8ft SSE swell at 10 seconds with a light cross-off breeze is your cleanest, most powerful shot. The water’s warm, and the crowd at Shida is often, so you’ll have company. For the second week, Saturday, 12th September is the only interesting call – tiny but glassy with that super-long period. It’s a longboard dream, but don’t expect any power.

Otherwise? There’s a lot of waiting. This is a typical blank run for an inconsistent spot like Shida. Forecasts can change, but right now, it’s a waiting game.

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.
