The Lowdown

Alright folks, Rusty here. Let’s talk about what’s cooking for Shida over the next few weeks. To be dead honest with you, this is a tough forecast. There are very few windows where everything lines up, and even the best options come with a heavy side of caution.

The first real chance for a surf comes on Sunday the 13th of September. The morning is a write-off with poor conditions, but the afternoon cleans right up. We’ve got a small, clean 2ft swell from the ESE with a solid 13-second period. The light breeze is cross-offshore, making for tidy lines. The combined swell energy is moderate at 248. It’s not going to blow your mind, but it’s a start. Shida is an inconsistent spot, so any rideable wave here is a bonus. Winds are light and cross-off, so expect clean faces – a good little session for an intermediate.

Monday the 14th offers a similar story. The morning is marginal with a cross-off wind, but the afternoon picks up a clean 3ft SE swell and a nice offshore breeze from the SSW at 16 mph. That offshore wind is a major positive—clean, groomed faces. The energy is moderate at 268. Again, not big, but honest surf.

Now, after Monday afternoon, we hit a real rough patch. Tuesday the 15th through to Saturday the 19th of September sees nothing but poor conditions: cross-onshore wind, lumpy water, and messy waves. Thursday brings a jump in swell height to 5ft to 7ft, but the period drops to a short, weak 6-7 seconds, and the wind is terrible. It’s not worth paddling out.

We then get a massive pulse of energy on Saturday the 19th and Sunday the 20th. Saturday afternoon shows a 11ft swell from the SE with a 13-second period and a massive combined energy of 4495. The wind and tide are favorable, but the report flat out says the swell is too big for this break. Sunday the 20th is the same story: 10ft SE swell, glassy offshore wind, and an energy of 2590. It’s going to be a washing machine. For an intermediate spot, that’s expert territory and frankly dangerous. For kite surfers, that open face and strong wind might be a dream, but for a paddle surfer, it’s a hard pass.

Monday the 22nd of September is a standout day for *size* again, but the same problem. A massive 16ft SSW groundswell with a 12-second period and energy of 9141. The wind is offshore and the conditions would be perfect, but again, it’s too big for this break. Same goes for the afternoon with a 10ft SSW swell and offshore wind.

The rest of the window from Tuesday the 23rd of September through to the end of the 16-day period is a continuous run of poor surf quality. The wind stays cross-onshore or onshore, the water gets lumpy, and the swell is either too small or too short-period to do anything with. A few small pulses of energy around the 26th and 27th are immediately ruined by strong onshore winds.

The Best of the Worst: If you’re determined to get wet, your windows are:
- Sunday afternoon, 13th September: 2ft ESE, clean, light wind.
- Monday afternoon, 14th September: 3ft SE, clean, offshore wind.

Both are small but honest. Everything else is either blown out, too big, or a combination of both. It’s a lean period, but sometimes you just have to take what the ocean gives you.

Stay safe out there.

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.
