December 2020 was anything but normal weather-wise (which coincides well with most of 2020!) as it was very warm and wet. December temperature and precipitation anomalies were much above normal (+4.2 C and 173% respectively) in comparison with the 30-year climate normal (1981-2010) for the province.
Climate extreme for the month: As also observed in November, maximum monthly temperature records were also broken in December for some sites. However, Fredericton broke their monthly record twice, first time on the 1st with 17.0 C then broke that record again on Christmas Day with 17.3 C.
