Farmer's Almanac was right again!!!

I read the Old Farmer's Almanac in September 2018 and they predicted a very snowy winter for Ontario, starting in early 2019. We've broken all the snow records in Ottawa, so the Farmer's Almanac is right again! I became a total believer a couple of years ago when we had the wettest June and July ever, and again, the Farmer's Almanac was bang on.

Looks like they were right!

What area do you live?

Joke’s on you Daniel!

Haha! Almanac was right Daniel! Record snowfalls in Quebec City this year! Hope it’s finally melting...

almanac

Our French-language forecast for Quebec is available only in the Canadian Edition of the Almanac, unfortunately. If you do not have a copy, try using Google Translate to translate the forecast on this page into French—that should help a little!

Good morning! love your many publications and you are really spot on for the vast majority. now if I look at the us map on the page 2018–2019 WINTER WEATHER FORECAST
( I live in Montreal) the green area would encompass Montreal by far if we draw a line across the border the shaded area ...but if I look at the Canadian map on the same page...well its a totally different winter. Can you shed some light here ! thanks... and great articles on gardening !!
