Accuracy
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!

That’s waaay better than average, Chad! Thanks for letting us know—and we’ll do our best to replay that performance!
WINTER
I HAVE NO USE FOR WINTER I ENJOY THE SUMMER BY FAR ALL YEAR LONG. IN THE WINTER YOU HAVE TO HAVE SO MUCH CLOTHING ON AND IN THE SUMMER FEELS MORE COMFORTABLE IN SHORTS AND T SHIRTS. I THINK WINTER SHOULD BE OUTLAW ( YUCK )
