Updates in hr min s Forecast update imminent
G’day, Rusty here. Alright, so we’ve got a bit of an interesting run shaping up for Shida over the next couple of weeks. It takes a few days to get going, with some small, iffy stuff on the 5th and 6th that’s mostly a write-off. The real magic starts to build from Wednesday the 8th and goes into a solid run of proper surf right through to the weekend of the 12th. After that, it drops off again into smaller, less reliable waves.
For the first standout, and honestly the pick of the entire period, look to Wednesday the 8th of July afternoon. The wind swings clean cross-offshore from the ESE at just 12 mph, and we’re looking at a solid 7 ft of swell from the SSE. That combined energy is a powerful 2877 (moderate to strong), and with a 16-second period, this is proper groundswell – great for wrapping into the point, just watch for those longer lulls between sets. Thursday the 9th and Friday the 10th are just as good, with clean 7 ft waves and pure offshore winds. Remember, anything over 8 ft is expert territory, and this sits right under that line, so it’s a good challenge for experienced surfers.
The second standout is Saturday the 11th of July. The morning shows a slightly bigger 8 ft from the south at a very long 17-second period, with clean, gentle offshore winds from the south at 9 mph. The combined energy is a very strong 3201. The waves will have plenty of push and shape, perfect for the reef setup here. Just a heads-up, Shida can be inconsistent, and on days like this, you can expect crowds.
The water is sitting at 71°F, which is 5° colder than usual for this time of year – that’s a notable chill, so a thicker steamer might be worth bringing. After the 12th, the swell backs off. The 13th and 14th are much smaller and weaker, then there’s a small but clean pulse from the 15th to the 18th with chest-high (4 ft to 6 ft) ESE swell and good offshore winds. The final days from the 19th into the 20th fade back to knee-to-waist-high, clean but ordinary.
So, lock in that Wednesday 8th through to Saturday 11th. The surf quality and conditions are about as good as it gets for Shida this far 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.
