The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the menu for Shida over the next couple of weeks.

Right off the bat, we’ve got a bit of a slow start. The first few days are a bit of a write-off thanks to onshore winds and generally weak energy. Wednesday the 26th has a clean 3ft SSE swell (284 combined energy), but the wind is cross-off, and the rating is nothing to get excited about. It’s surfable, but it’s not the kind of thing you’d rush to the beach for.

Thursday and Friday stay pretty ordinary with onshore winds and small, short-period swell. The energy is moderate (around 227-297 combined energy), but the wind is killing it. You’ll be sitting in the parking lot wondering why you bothered.

The weekend of the 30th and 31st is small and weak. Sunday morning the 30th has a glassy 2ft E swell (93 combined energy), which is about as weak as it gets. The water is about average for this time of year, nothing out of the ordinary. But it’s glassy, so if you’re desperate for a longboard and a paddle, you could get wet. The crowds at Shida can be an issue, so expect a few others with the same idea.

Now, the first real standout comes on Wednesday the 2nd of September. The wind goes offshore from the south, and we see a solid 5ft S swell with a 13-second period (978 combined energy). That’s a proper groundswell. The morning is clean with moderate offshore wind, and the wave energy is ramping up. This is the best on offer in the first week. The 6ft swell on Wednesday afternoon is even bigger, but it’s a bit much for the average joe. For the experienced surfer, this is the window.

Thursday the 3rd of September keeps the 5ft S swell going with fresh offshore wind, but the energy is a bit lower (701 combined energy). Still a very good day, just not the standout.

After that, the swell drops back through Friday the 4th, and the weekend of the 5th and 6th is back to poor onshore junk. The combined energy drops to around 194-276, and the wind is wrong.

The second week looks more interesting. Monday the 7th of September has a 5ft SSE swell with clean cross-off wind (591 combined energy). That’s a solid, surfable day. But the real story is Monday afternoon: the swell jumps to 10ft from the SSE with a 14-second period, combined energy of 2971. That’s a massive, powerful groundswell. The wind is favorable, but at 10ft, this is expert territory only. This is far too big for beginners, and even intermediate surfers will be in over their heads. It’s only for the brave.

Tuesday the 8th of September is even bigger: 13ft to 15ft from the SSE, with 12-second period and combined energy over 4500. That’s a monster. The wind is cross-shore, so it won’t be perfect, but the power is there. Again, experts only. This is a serious, heavy ocean.

After that, the swell drops rapidly through the 9th and 10th, but the wind swings onshore and choppy, so it’s back to not worth the drive.

So, the standout window is Wednesday the 2nd of September through Thursday the 3rd, with the offshore wind and solid groundswell. For the brave, Monday the 7th and Tuesday the 8th offer massive, powerful swell, but you’d better know what you’re doing. The rest of the period is mostly small or blown out.

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.
