Table - best surf conditions forecast for Shida over the next 16 days.
G’day, I’m Rusty. Let’s talk about Shida and the next couple of weeks. It’s a bit of a rollercoaster, with a long stretch of pretty average conditions and then a couple of days that could be absolutely firing – but only for the experienced crew. The water temp is 75°, which is right around normal for this time of year, so no surprises there.
The first real chance to paddle out is Monday, July 13th, but it’s nothing to get excited about. We’ve got a 4ft swell from the SSW, but with a cross-shore breeze and the threat of thunderstorms, it’s messy. The combined energy is moderate (475). By Monday afternoon, the swell drops to 3ft with a light cross-offshore breeze, and the energy drops to 256 – you’ll get a wave, but it’s not going to be a session you remember.
Tuesday, July 14th, starts off glassy – I love that – with a 2ft SSW swell (162 energy). It’s small and clean, but very ordinary. The afternoon sees a 15 km/h offshore wind from the south, cleaning up a 2ft swell (130 energy). It’s surfable, but again, nothing special.
From Wednesday, July 15th, through to Monday, July 20th, it’s a real grind. The swell is tiny, the wind is mostly onshore or cross-off, and the energy is weak to moderate. Wednesday morning has a 1ft swell (82 energy) with a strong cross-off breeze – that’s barely a ripple. The wind picks up and the swell gets a bit bigger towards the weekend, but it’s all cross-onshore and choppy. Saturday the 18th has a 4ft ESE swell (310 energy), but it’s a cross-on mess. Sunday the 19th serves up a 5ft swell (444 energy), but it’s onshore and cross-shore, making it marginal. Monday the 20th is more of the same: 5ft ESE swell, but cross-onshore and choppy (586 energy). This whole stretch is a write-off, honestly. The wind is just ruining everything.
Now, here’s where it gets interesting – but you need to be an expert. On Wednesday, July 22nd, we get a proper pulse. The morning is glassy – dead calm, 7ft swell from the east with a period of 11 seconds, and the combined energy is a massive 1228. That’s strong, powerful, and clean. The afternoon is an 8ft NE swell (2093 energy!) with a 10 km/h offshore wind. This is going to be a serious, heavy day. The swell direction is from the east and NE, which matches the optimum SE direction for Shida pretty well, but with that size and power, it’s for experienced surfers only. The long period (11 seconds) will give it some real grunt and longer waits between sets.
After that, the surf drops back down. Thursday, July 23rd, has a 4ft ENE swell (385 energy) with a cross-shore breeze – marginal. Friday, July 24th, looks better with a 3ft SSE swell (296 energy) and offshore winds in the morning, cleaning up to 3ft in the afternoon (235 energy). It’s surfable and clean, but a far cry from the 22nd.
The final weekend, the 26th and 27th, is a return to poor form: cross-onshore winds, 4ft to 5ft swell, and choppy. No good.
So, if you’re looking for the standout, it’s absolutely Wednesday, July 22nd. The morning glass-off with that 7ft east swell is a dream scenario for an expert, and the afternoon is almost as good with the offshore wind. But don’t even think about taking a beginner board out there. For the rest of the period, it’s mostly a waiting game. The first week is pretty bleak, and the second week only has that one real highlight.
Stay patient, and keep an eye on the forecasts – things can change.
Rusty out.

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.
