Ice storm not mentioned

Didnt see anything in April about an ice storm! Going on 2nd day now...so far have not lost power..touch wood....got lots of food, plenty of candles and the firewood is dry....bring it on Mother Nature....

There really WAS an ice storm

There really WAS an ice storm in April in Etobicoke. I’m not lying. They’re not always accurate.

lets see predictions so far of farmers almanac

So judging by information you posted for Ontario, November was a lot warmer, you said it would be a lot cooler. December was very cold you posted it would be average. January was extremely cold, coldest in decades, many broken records for consecutive -10 degrees days were broken you predicted january being extremely warm. February was very warm, you predicted it will be cold. March was 1-2 degrees colder than average, you predicted extremely warm march. April so far extremely cold, you predicted neutral. So far this year you are 0/6. and you are not just wrong...no. you are completely wrong by complete opposite extremes. are you not ashamed to call yourself a professional?

Get a life

Get a life its a prediction not facts. You sound like a little boy with no profession. Farmers almanac has been around for ever and there summer predictions ( all i care about for farming) have been correct for years. Plus me and almanac are talking about a general consensus of the month and a season. Not a specific day in the future. Have a great day with your "proffesion"!

this is by far the worst prediction i ever witness in my life

For as long as I lived I have never seen less accurate weather than this. this should be criminal to post lies like this. I am in ontario and we had cold cloudy/rainy/snowy days the first 2 weeks. maybe 3 half days of sun and next 9/10 days supposed to be more rain 0 hours of sun.
. farmer predicted less than average precipitation and average temperature. well it looks like it will be the rainiest/snowiest April on record and 5 degrees cooler than normal. You lost all my credibility. If i knew I could of booked a vacation south. I need sun I have a very bad case of SAD.

WHY COMPLAIN??

Logically, the weather is "GOING TO DO WHAT IT'S GOING TO DO!"..... Enjoy it for what it is!! If it's sunny and cool or sunny and hot...it sure as heck beats the Winter and it's cloudy, dreary days. I have had S.A.D.S since childhood and ANY SUNNY DAY in Spring or Summer or Autumn - warm or cool or blistering hot beats the depressing days of Winter! BUT..... this IS CANADA and I still love this country despite it's dull, gray Winters!

What does SADS mean?

What does SADS mean?

weather

Give me hot summer days and mild winters. I live in Northern Ont. and the winters can be a tad too long for my liking. We spend the month of April in Florida and love the heat!

sad

It means Seasonal Affective Disorder and I suffer from it.....some winters are worse than others for me! Taking Vitamin D helps.

I absolutely can't stand when

I absolutely can't stand when people whine and complain about the weather not being boiling hot!! Stop blaming the weather person!! They aren't Mother Nature!!!! Who wants boiling hot weather just to spend all day trying to cool off in ac???!! I hate boiling hot weather and every month should feel like autumn!!!!!! Boo hoo I hope the summer is cool as possible!!!!
