Looking to an animal to predict the weather isn’t that strange of a concept since there is an entire day dedicated to it in February. But using a pig’s spleen to predict the weather isn’t quite as common.

But that is exactly what Jeff Woodward does each year, with a surprising amount of accuracy. Each year he looks at pig spleens taken from pigs in southern Saskatchewan and predicts the weather not just weeks, but months ahead of time.

Woodward learned to predict the weather using pig spleens from his uncle Gus, who had learned it from his father. He claims an accuracy rate of 80-90%, and has a brand new prediction for this winter and the upcoming spring.

In February, Woodward called the snow we received and the mild start to the month. His prediction for the rest of the month and into March is colder and windy. And he doesn't think much will change after that.

"The spleen basically says it's a cooler and longer spring than I think what we've had in the past. It doesn't look like a real warm spring. So June is relatively cold. May, there's a bit of a reprieve in the middle of the month, but in general it's going to be a cool, long spring."
