The Lowdown

Alright folks, Rusty here. Let’s break down what Shida has cooking in this 16-day window.

First thing, the start is dead. We’re looking at a blank run from now until Wednesday, August 7th, with nothing but raw, lumpy conditions. The water’s sitting around 81°F – pretty average for the season.

The story starts to flip on the 6th of August, Thursday afternoon. That’s when we finally get a shot. Shida is exposed, and that 8ft SSE swell is packing some serious energy (3039). The wind swings cross-offshore from the SE, cleaning it right up. This is your first real chance, but with a 14-second period, that’s a long-period groundswell. It’ll peel nice here, but the sets will be spaced, so be patient.

Friday the 7th holds similar promise in the morning – 8ft from the S, still clean with that cross-off wind, but there’s a risk of thunderstorms. It’s not perfect, but it’s the best we’ve got. These two days are the standout for the first week.

After that, it gets messy. A big wind event from the north north-east hits hard on the 10th and 11th, with gusts near gale force, blowing everything out. The energy is still moderate, but you don’t want to be out there.

We get a little glimmer on Saturday the 16th – a 7ft ESE swell with light cross-shore winds from the ENE. It’s marginal but clean-ish.

The real wild card is late in the window. On the 17th and 18th of August, the swell builds again – up to 8ft and 10ft from the ESE with moderate energy (3147). But the wind is the killer; it’s mostly cross-on and strong. This setup is promising but uncertain, so far out. If those winds shift, it could get good, but right now it’s kite surfer territory.

Honestly, this 16-day outlook is a mixed bag. The only real standouts are Thursday the 6th and Friday the 7th. Get that clean S swell while you can.

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.
