Canadian Climate Survey 9: Winnipeg’s Average Temperature Rises 0.8 ˚C From 1961-1990 Average
June 18th, 2012
The Canadian Climate Survey is tracking historical and average temperatures in cities and towns across the country, as part of an effort to put something of a local face on global climate change.
Temperature Extremes: Since 1875, Winnipeg has experienced 17 years in which the average temperature reached or exceeded 3.8 ˚C, and 8 of Winnipeg’s 17 hottest years have occurred since 1990. In contrast, only 1 of Winnipeg’s 17 coldest years has occurred in the same timespan.
Long-Term Consequences: Although Winnipeg is experiencing long-term warming, over the past decade the 10-year average temperature has returned to 3.5 ˚C, the same as it was during the 1980s.

Not a surprising finding. Generally climate researchers assume that you need a 30 year moving average is required to dampen down the noise in a noisy system.

Thanks for mentioning this. I’ll make the appropriate adjustments in my future posts.
