Residents of Amherst should prepare for an unsettled week of weather, as Environment Canada forecasts frequent rain and dropping overnight temperatures through April 21, 2026. While daytime highs will hover between 7°C and 12°C, the incoming cold spells bring a frost risk for those beginning early garden work.
The forecast includes rounds of showers arriving on Wednesday, Friday, Sunday, and Monday. Wednesday morning features gusty southeast winds reaching up to 40 km/h alongside clearing rain. Although Saturday is expected to be a sunny day with a high of 7°C, the nights following Friday, Saturday, and Monday will see temperatures dip to -1°C and -2°C, creating conditions where frost may develop.
For local gardeners, these temperatures serve as a reminder that the region remains well ahead of the average last spring frost date. According to data from the Old Farmer’s Almanac, the historical average last frost date for the area is June 3. This date is calculated using a 30 percent probability threshold, meaning there is a consistent chance of frost occurring in the weeks leading up to and following that time.
Experts advise caution during this unpredictable spring period in Cumberland. With spring temperatures historically ranging from 0°C to 10°C during this time of year, planting frost-sensitive crops too early can be risky. Gardeners are often encouraged to wait until later in the season to ensure plants are protected from these final cold snaps.
