November forecast was great, but February is lousy

The Farmer's Almanac's Atlantic Corridor predictions were very precise on the average temperature in Nov 2020 (predicted 50F got 49.94F) and Dec 2020 (predicted 38F got 38.16F), but it was 3 degrees warmer in January than predicted. They predicted snow in December and early March, but then we got a lot of snow in February 2021! They got February completely wrong. Maybe we got our March snow in February instead.

Maryland Still Waiting for Their Blizzard

Now, many of us Maryland residents are praying and wishing for a lot of snow in March. Yes, while we are at home a good foot or two will be good for the children and us adults to play in. Just watching the beautiful snow, with some hot cocoa is so peaceful. Come on Farmer's Almanac you said in the Northeast states in early March were getting a lot of snow, were counting on you. Don't let us down, cause thus far we have been let down.

We still get snow

Except for vicious anomalies like the Blizzard of 78, something no one wants to go through again, we've always had more or less the same amount of snow with some years drier than others. What those who bemoan how we used to get more snow forget is they used to be a a couple of feet shorter. As such 6 inches seemed like a lot more then than it does now and a foot? That's a lot when you're not even four feet tall.

We Need Snow

Now I hate to say the farmers almanac is wrong, but if you look in the past years. And believe me I do. It has been right on point. Summers and winters and I go to the farmers almanac for gardening. Now my son is 3 years old we are in jersey. He has not seen 1 blizzard in his life. And it’s sad very sad! We may get a few inches here and their but it’s not like what I/we had back in the day. It’s saying February we are having a snow period. I’m just praying for a blizzard. Or else we are takeing a trip to the mountains haha.

wrong

I wanted to know about the summer. I predict cold spring-summer-fall 2021. After reading what they have for winter 2021 i no longer trust this site. They are way off with their forecast.

Weather

Totally wrong again. Just like the weather channel. It goes to show you with all the technology long range forecasts cannot be accurate. Forecasts are hard enough for predicting the weather 10 days in advance let alone 3 months or more.

Weather reporting from Farmer's Almanac is Wrong!!!

I love the snow and want the snow as reported from Farmer's Almanac that would take place here in Maryland. I am so sick and tired of the weather channel and the weathermen and women saying were going to get all of this snow and it ends up being rain. Now, Farmer's Almanac is saying were looking at a snow storm in early March first they said it was going to happen in mid February. SMH

s'no joke

The Editors's picture

Remember our accuracy rate iss 80 percent, not 100 percent. 

We are getting snow here in New England and some people are starting to think, be careful what you wish for! 

Weather report been wrong so

Weather report been wrong so far this year(2/6/21)

Winter 2020-2021

Guys chill, winter is the hardest season to predict, and where I'm at even though I've gotten 18 inches of snow. My location is still 13 inches below its average snowfall to date. Yes they may have been wrong, just note if you tried to make a forecast in October how the entire year will be like. I'm sure you wouldn't do as well as them.
