May 2019 proved to be the coldest May since 1974 in the Maritimes with temperatures about two or three degrees below normal.
The month started out with some warmth in Greater Moncton but it turned colder near the middle with snow recorded as late as the 21st before a slight recovery at the end.
Overnight lows were cold with six nights either at or below freezing and most minimums were in the low single digits.
Cold, damp and cloudy weather stunted growth and forced farmers to delay planting because fields were saturated.
Only three days reached or exceeded 20°C and the thermometer came nowhere near 30°C at any time of the month.
