Officially, the monthly mean of 8.0C at YWG airport was the 10th coldest May since records began in 1872, tying May 1954 and May 1967. It was the coldest May in Winnipeg since 1979 when a mean of 7.3C was recorded. Only a last week warm spell prevented May 2002 from finishing in the top 5 coldest Mays ever. In addition, the month finished as the 2nd snowiest May on record, thanks in large part to an unseasonable snowstorm on May 9th that dropped 20.0 cm of heavy wet snow at the YWG airport (16.8 cm at my location) It was the heaviest May snowfall since May 1 1967 when 21 cm fell, the heaviest one day May snowfall ever. The official monthly snowfall of 29.0 cm at YWG airport was second only to the 32.0 cm that fell during May 1931. It was also a windy month, with 10 days averaging over 10 kmh mean windspeed at my location.. including 7 days with peak gusts over 50 km/h. The cool month ended an abnormally cool spring (March - May) , averaging over 3 degrees below normal at -0.6C (normal 2.8C) It was the 18th coolest spring since 1872 in Winnipeg, and the coldest spring since 1997 when a mean of -1.0C was recorded.
