The Lowdown

Alright, Rusty here, let’s have a look at what’s cookin' for your local stretch.

Right now, it’s a bit flat and quiet out there. We’re looking at a long gap from Friday the 28th through the end of the month with only small, ordinary dribble and poor conditions on offer. Monday the 31st might give you a tiny, clean waist-high wave with light offshore wind around Shida, but it's weak with combined swell energy at only 67, so it’s more of a paddle than a proper session.

The first real standout arrives on Tuesday the 1st of September. The morning at Shida is looking tasty with a clean 3 ft wave from ESE at 11 seconds and light cross-offshore wind. The energy is moderate at 323. The water is sitting at 82°, which is a touch warmer than normal for this time of year – nice for a long session in boardies. The afternoon cleans up even more with a 3 ft swell and the same clean conditions. This is the best on offer in the first week – get it while it’s good.

We then slide into a couple of decent but not epic days. Wednesday the 2nd is clean again with clean 3 ft waves from the south and offshore wind, the swell energy is solid at 335 in the afternoon. Good for a fun, uncrowded session if you’re lucky. However, Thursday the 3rd looks poor despite the clean conditions – the wind is too strong and the quality drops right off.

The following week is where a bigger swell starts to build. Sunday the 6th of September brings a notable pulse of south swell, pushing to 6 ft with a very long period of 14 seconds. The combined energy jumps to 1287. This is proper groundswell – it’ll have plenty of power and longer lulls. The wave state is clean but it’s a cross-offshore wind. Keep in mind, this kind of long-period swell can make a beach break like Shida a bit shifty and closed out in places. The conditions are a little on the clean side but it’s gonna be a serious paddle. This swell hangs around into Monday the 7th, with a clean 7 ft to 7 ft from the south with offshore wind in the afternoon and energy at 1343 – that’s expert territory size-wise, and it looks like the true standout of the whole two weeks for the confident crew. For the average punter, this will be too big.

After that, the energy drops again. By Friday the 11th of September, things calm right down. The morning at Shida looks glassy with a light NNW breeze and a clean 5 ft south swell. That’s a dream window for a longboard or a mid-length, with gentle offshore wind in the afternoon. Energy is moderate at 487. It won't have the punch of the early week but the conditions will be perfect.

Overall, Tuesday the 1st is your best bet for a fun, clean, manageable wave, and expert surfers should circle Monday the 7th for a proper, clean, big swell session. 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.
