October 2018 proved to be very different from October 2017 in Southeast New Brunswick.
While it was warm and dry last year in Greater Moncton (the second warmest October since 1881), it was the opposite this year – cool and wet.
Temperatures were below normal with only one day reaching 20°C and a hard frost arrived by mid-month.
Only seven days were dry with three major rainfall events and snow fell on three days – briefly settling on the ground twice.
