Updates in hr min s Forecast update imminent
Alright folks, Rusty here. Let's get into what's cookin' at Shida over the next couple of weeks. It's a bit of a slow starter, but there's a serious pulse of energy building for the second week that's got my attention.
Right off the bat, the water temp is sittin' at 71.6°, which is a couple of degrees cooler than normal for this time of year – you'll wanna feel that extra little chill.
The first few days are pretty quiet. Sunday the 5th and Monday the 6th are pretty much a write-off with weak windswell and messy wind. Not worth paddling out. Tuesday the 7th stays poor, so we've got a solid stretch of nada to start.
Things finally start to get interesting from Wednesday the 8th. The swell is on the rise, but the wind is still cross-onshore, so the conditions are a bit of a mess – marginal at best. The real shift comes on Thursday the 9th afternoon. We've got a solid 7.5ft S swell rolling in, with a long 16-second period, and the wind is swinging light cross-off. The wave energy is strong (2799). This is where it gets good, but that 7.5ft is getting up there – this is for experienced surfers only.
Then, the real standout. Friday the 10th and Saturday the 11th are absolute crackers. Friday morning is clean with the same 7.5ft S swell and a light cross-off breeze. By Friday afternoon, we're looking at gentle offshore wind and that same strong energy (2706). Saturday the 11th morning is the gem of the whole forecast: 7.5ft S swell, a very long 17-second period, and a gentle offshore wind from the SSW, making for glassy conditions. The combined energy is pumping at 3351. This is the call. The south swell at that size and period is gonna be a freight train – a proper groundswell. At a point or reef, it'll be world-class, but be aware that this much energy with that long period can be tricky at a beach break, running too straight. Crowds are likely here, it's an exposed spot, but for those in the know, this is the session to target.
Sunday the 12th is still solid, but the swell starts to back off into the 5ft to 5.5ft range. Still clean, especially Sunday afternoon with a gentle offshore, making for a really fun, manageable size.
After that, the second week drops right off. From Monday the 13th into the third week, we're back to small, weak surf with combined energy in the low hundreds. It's clean and rideable on a longboard, but nothing to get excited about. There's a little bump around the 17th and 18th with some clean, offshore winds and small 3.5ft to 4ft SE swell, but it's pretty ordinary compared to that big pulse.
So, the short story: you've got a massive gap at the start, but the 10th, 11th, and 12th of July are firing. Get on the 11th if you can handle a solid, powerful south swell.

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.
