The Lowdown

Right, let’s have a look at what’s shaping up for Shida over the next couple of weeks.

The first thing to say is, this isn’t a classic run of surf. There’s a tricky start, a few glimmers of hope, then a massive pulse of swell that’s just too much for the place. You’ve got to pick your windows.

The first proper session worth getting out of bed for is Sunday morning 19 July. We’ve got a clean 4 ft swell out of the ESE, a gentle offshore wind, and the water’s sitting at a pretty normal 77°. The combined energy is moderate (288), so there’s a bit of push. It’s not going to be pumping, but it’ll be clean and surfable. The inconsistency here is a bit of a pain, but it’s the best of the early week.

Tuesday 21 July is another decent shout. Both morning and afternoon have 4 ft from the east with a 10-second period, and the wind is light offshore or cross-off. The energy is moderate again (290 and 278), and the water is clean. It’s not a standout, but it’s reliable.

Now, the real interest—and a bit of a warning—kicks in from Monday 27 July. The swell jumps up, and by Tuesday 28 July we’re looking at 10 ft to 12 ft from the SSE, with a very long period of 14 to 17 seconds. The combined energy is massive (up to 6,592). That kind of size is expert-only at Shida, and the long period groundswell might make it break a bit too straight for a beach break. The wind is clean, but it’s a serious step up. If you’re not a seasoned charger, stay out of the water.

Wednesday 29 July is absolutely huge: 23 ft in the morning, with insane energy (46,702). That’s not a surf day for anyone. The ocean is angry. The wind is offshore, but the size is just mental. Same goes for the afternoon at 18 ft.

Things settle down by Thursday 30 July into the 1st of August, with solid 7 ft to 8 ft SSW swell and moderate offshore winds. The energy is still strong (over 1,000), and the conditions are clean. This is the best run for the confident intermediate to advanced surfer. The Friday 31 July and Saturday 1 August mornings are the pick of the bunch: 8 ft and 6 ft, with clean offshore winds and moderate energy. It’s not a world-class day, but it’s a proper session.

The very end of the run, Sunday 2 August, drops right back to 2 ft with a very long period (16 seconds) and glassy conditions. It’ll be tiny and clean, maybe a longboard cruiser.

So, overall: the standout days are Friday 31 July and Saturday 1 August for the best combination of size, direction, and clean wind. The early week has some small but clean waves, and the big spike at the end of July is strictly for the experts. Don’t go chasing the 23 ft day.

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.
