It's just weather
Why are people arguing in a weather forum? I wouldn't live anywhere else! Enjoying all 4 seasons, and the unpredictability of our weather makes me appreciate every day.
Weather
So far in my area all predictions have been 100% accurate. To everyone else, get over it, if you dont like your weather, move somwhere that will help you whine, complain and b*tch less. Have a great summer, happy planting everybody
Hot weather
On May 1-2, the temperature was 28 degrees Celsius in Etobicoke. Maybe May will be ABOVE average. They said May 1 mild. 28 degrees isn’t mild. It’s hot. At least it’s better to not have to wear winter coats.
Be Postive
Enjoy any weather we get . Can't control it ,hot ,cold, warm make the best of it . Remember Wynne says the carbon tax we pay help climate control. No that's smog at its best.Enjoy the weather .no tax can help it.lol
Smog?
Dave, have you already forgotten all the real smog advisories of a few years ago? That's why we closed the coal fired plants. I hate higher gas prices as much as the next guy but the best way to move past dangerous fossil fuels is to make them more expensive than alternatives.
Enjoy the summer whatever may come!
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....
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!
