The Lowdown

Alright, Rusty here. Let's have a look at what Shida has got cooking for us over the next couple of weeks.

Right off the bat, the start of the period is looking sweet. Monday the 24th of August kicks off with a cracking clean swell. We’ve got a solid 3ft groundswell out of the SSE with a super long 18-second period, packing a moderate energy punch (944). The water’s sitting at a balmy 82°, which is about normal for this time of year. With a light offshore breeze from the SSW at only 3 mph, the surface is going to be glassy. This is the standout session of the whole window – get out there if you can.

The quality takes a dive from Monday afternoon onwards. By Tuesday the 25th, the wind picks up to 15-19 mph, blowing cross-offshore, and the swell jumps to 6ft but the period drops. The afternoon is a write-off, and Wednesday the 26th isn't much better, with wind ruining the shape.

We hit a real dry spell from Saturday the 29th of August all the way through to Monday the 1st of September. During this stretch, the waves are tiny (2ft to 3ft) and the wind is blowing onshore or cross-shore, making for choppy, poor conditions. Not worth paddling out.

Things look a little more promising on Tuesday the 2nd of September. We get clean 3ft waves from the ESE with an 11-second period and light cross-offshore winds. The energy is weak (232-246), but it’s surfable. Wednesday the 3rd brings a bit more size but also stormy winds and rain, turning it into a mess.

By Saturday the 5th of September, the swell size picks up to 6ft from the ENE with a short 9-second period. The energy is moderate (1050), but the wind is messy. Then Sunday the 6th brings a proper strong offshore wind at 25-28 mph, which cleans up the 5ft swell, but that wind is so strong it’ll make paddling out a nightmare. That day is more for the kite crew.

Finally, Monday the 7th of September looks like a nice finish to the period. Clean 3-4ft waves from the SE/ESE with a gentle offshore breeze. The energy is low (274-353), but the conditions will be smooth. A good way to end the run.

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.
