The Lowdown

Alright, let’s get this sorted. Rusty here.

Look, the overall picture for this region over the next 16 days is promising but with a bit of a wait. The forecast really kicks into gear around the middle of the period, offering some proper standouts. But there’s a dry spell you’ll have to sit through first.

The first decent recommendation is Monday the 20th at Shida. The water temperature is sitting right on the money for this time of year at 77°F. But honestly, this is just a warm-up. Monday morning sees clean, surfable waves at 3ft from the east, with light offshore winds and moderate combined swell energy (148). It’s small and inconsistent, but there are waves.

Tuesday the 21st is where it starts to get your attention. The swell picks up to 4ft, still from the east, but the period stretches to 10 seconds, and the energy jumps to a moderate 290. With a light offshore breeze making it clean, this is a proper little session. Not huge, but quality. The afternoon stays clean but the wind turns cross-off, so still rideable.

Wednesday the 22nd morning hangs in there with 3ft east swell, 10-second period, and slight air – glassy clean. It’s still only an inconsistent spot, so patience is key.

Then we hit a proper lull. From Thursday the 23rd all the way through to early Monday the 27th, it’s pretty grim. Winds swing onshore or cross-shore, wave heights drop, and scores tank. There’s nothing worth paddling out for during that stretch. A solid 4-day gap with no real recommendations.

Now, here’s where it gets interesting. Tuesday the 28th of July is the true standout of the whole forecast. The afternoon at Shida brings 4ft of swell from the SSW, a very long 14-second period, and massive combined energy of 718. That is a serious pulse of moderate-to-strong energy. The late glassy conditions mean it’ll be smooth as silk. The consistency is poor here, and it’s not a high-rated spot, but that combination of clean, long-period groundswell from the SSW hitting this exposed break is a high-session potential. This is the one to circle. The afternoon is the call.

Wednesday the 29th keeps the SSW groundswell going at 4ft, 14-second period, and energy still over 600. The morning is choppy, but the afternoon cleans up with a light cross-off breeze. Another very good window.

After that, the swell backs off. Thursday the 30th and Friday the 31st offer small, clean waves in the 2ft to 3ft range with offshore breezes. Fine for a grovel, but nothing to get excited about.

The final few days of the first week of August show a pulse of longer-period SSE swell with moderate energy, but the winds get tricky again. The pick there is Monday the 3rd of August afternoon, with 2ft from the SE, a 14-second period, and moderate offshore wind making it clean with moderate energy (489). Not the standout, but worth a look if you’re hanging for a wave.

Best on offer: Tuesday the 28th of July afternoon, and then the afternoon of Wednesday the 29th of July. Get on it.

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.
