The Lowdown

Alright, let’s break it down. The only break in the game for the next 16 days is Shida. It’s an exposed, inconsistent spot for intermediate-level surfers, and it can get crowded. Water temp is 82°F, which is a touch warmer than normal for this time of year – you’ll notice the extra warmth.

The window opens Thursday, August 27, with a small, short-period SSE swell around 3ft, period only 10 seconds, and the combined energy is weak (243). Wind is cross-off and light, so conditions are clean. It’s tiny but rideable on a longboard or foil. That afternoon, the swell switches to a 2ft easterly with a better 13-second period, energy up a bit (287), and light westerly wind keeps it clean. Thursday morning is the pick of the first few days.

Friday the 28th starts messy – a cross-on wind with a weak 2ft easterly swell, not great. But Friday afternoon cleans up: a 3ft, 8-second period SSW swell, light cross-off wind, and clean conditions. It’s not epic, but it’s surfable.

Saturday the 29th and Sunday the 30th are poor. Small 2-2ft easterly swell with onshore or cross winds and low energy (144 down to 99). Sunday afternoon sees a brief glassy moment, 2ft and 11-second period, but it’s barely surfable.

Monday and Tuesday (Aug 31 – Sep 1) are a washout – poor conditions, onshore wind, messy chop. The swell bumps up a little to 3ft on Tuesday but the wind is cross or cross-on, making it ugly.

Wednesday September 2 is a turning point. Morning brings a 3ft southerly swell, 11-second period, moderate offshore wind, clean conditions, and moderate energy (479). That’s a solid session for the intermediate surfer. The afternoon sees 4ft, 10-second period, fresh offshore wind, but the energy is still good (473). Wind is a bit stiffer but still clean.

Thursday September 3 gets strong offshore wind (25 mph) with 4ft southerly swell. It’s clean but that wind is so strong it’s hard to paddle into. The energy drops a bit (410). This is for the experienced crew.

Friday September 4 is the standout. The morning shows an 8ft SSE swell, 11-second period, massive energy (1699), and cross-off wind. That’s a big, powerful groundswell. The swell direction is from the SSE, which matches the optimum SE direction for Shida. It’s a big day – not for beginners, only for experienced surfers. The afternoon drops to 8ft, energy still huge (1197), but the wind goes cross with a slight chop.

Saturday September 5 through Monday September 7 are blown out. Onshore winds from the NE, 6ft to 8ft, messy and choppy. Not worth it.

Then comes another big moment: Tuesday September 8. Morning is glassy, dead calm, with a 7ft southerly swell, 11-second period, and energy at 1180. That’s world-class conditions for experienced surfers. The afternoon keeps it going with an 8ft southerly swell, moderate offshore wind, and energy at 1424 – excellent but again for experienced riders only.

Wednesday September 9 and Thursday September 10 see the swell dropping but still significant (5ft to 8ft). Wind is strong offshore on Wednesday, but the period drops to 8 seconds on Thursday, making it less powerful. The energy stays moderate to strong (868 to 803). Conditions are clean but choppy from the wind.

Friday September 11 brings a 7ft north-easterly swell, 9-second period, clean cross-off wind, and energy at 1126. It’s a solid end to the forecast, but the swell direction is not ideal for Shida.

Overall, the best windows are September 2 morning, September 4 morning, and September 8. The 8th is the absolute standout: glassy, big, clean, and powerful. Just remember, Shida is inconsistent, so these windows are rare. Make the most of them.

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.
