Since this is a site that cares about accuracy, I'll mention that while winter wheat is planted in the winter, it's harvested in the summer or fall. It doesn't grow fast enough to be harvested in the spring. Instead, it's a way of getting a boost on the season by getting the roots established early. I don't think there is anywhere it can be harvested early enough that one can plant two crops per year in the same field.

(If you want to claim that you are technically correct, I'll concede that it is true that hypothetical Florida or Alabama winter wheat might be harvested in May. I hadn't even known that they grow winter wheat there!)
Who is harvesting winter wheat in the fall? Even here in snowy Canada it's a late harvest if the winter wheat comes off in August. Mid-July is typical. Spring wheat is a different story.
I had assumed that most of Canada would be later than the Northern tier of the US, but apparently I'm wrong. I wonder if it's because the summer days get longer the farther north you go, and at some point you actually get earlier ripening? Or maybe it's all local weather. In any case, thanks for the correction.
It is, but you don't find much winter wheat outside of Southern Ontario, which is actually pretty far south in the grand scheme of things. The most southern end of the province is on the same plane as California.
The Canadian prairies, where most of the wheat is grown, are all about the spring wheat. That's typically a September harvest.
> Idaho, Minnesota, Montana, Oregon, Washington, and Wyoming
Only one of those states is not contiguous with Canada. Given much of the same environment, they share a lot of the same farming practices as western Canada. In other words, your dates no doubt include spring wheat, despite what the opening section of the document says. This explains the wide variances (July - September) in some cases, with winter wheat being the early crop and spring wheat being later.
> And the world's farmers already started planting more wheat 4 months ago, when wheat futures rose due to possibility of Black Sea conflict.
> India went all-out planting more wheat, looks set to continue a 3yr streak of rapidly increasing wheat exports. The US planted four MILLION more tons more wheat seed last fall than usual. Aus, Canada, Argentina, South Africa, even Brazil getting in on it.

PS, you can get even more data, further back in history, directly from the USDA [2], but it is a little difficult to navigate this site. This link [3] might work for everyone, it is a query for acres of wheat planted all the way back to 1919.

So there's a gap in production, regardless of where they get their wheat from, I guess is what I'm trying to get at.
