A new fan

I've been monitoring your site for the last several months and am very impressed by your accuracy. I have already asked santa for a copy for Christmas and shown him where to he can purchase a copy. After reading the reviews I'm anxious to read the new 2020 edition.

Nov 23 2018

Another cold day starting out at -12.8 C Way below the predication.


This September and October we had a lot more preciptation as was predicated. November has been Much colder than the last 10 years . The temperature has reached -10 degrees C. three times this month . We have so much more snow this year than the last three years .
Not sure what the normal is but we have much more wind this year in Sept. Oct. and November.

Your weather prediction.

Thank you for the kind words, Michelle! We are happy to hear that you enjoy our content!


Your weather forecast has been way off throughout the spring and summer, and now fall for 2018. I live on the northern shore of mainland Nova Scotia and the weather has been almost opposite to the forecast. We have had a hot and dry summer, with only two good rains since mid June. You really missed it for 2018!

Good Job

I was given your book last Christmas and read it from cover to cover.
A lot of great information in it.
You happen to be on the mark forecasting.
Hope I get another book for Christmas this year. I have asked for it.

All you want for Christmas...

Thanks for this delightful message, Breda. So happy to hear you enjoyed the Almanac. Remember, if something happens and Santa fails to bring you the 2019 edition, we can tell you where to get one—or perhaps you want to tell “Santa” where to get one! In that case, go to Almanac.com/wheretobuy

Happy holidays!


your predictions were spot on last year hopefully same this yr
