BC Tmax Grid

Environment Canada Monthly Summary Grid by Decade
Tmax – 25 years worth of data or more – 80% of data – End Year 2015/16/17
British Columbia

2010s are the hottest decade 25% of the time, but I would argue overrepresentation due to many stations only going back to the 1970s.

The 1950s are the least hot decade. By far.
