Climate Trends
Historical Climate Trends for Timmins, Ontario Daily climate data from Timmins Victor Power A weather station, obtained from Environment Canada, was averaged to obtain monthly values for temperature and precipitation (Environment Canada, 2011). Seasonal climate values (winter –DJF and summer ‐JJA) were calculated by averaging the monthly data. Temperature and precipitation data, for the years 1956 to 2011, are displayed annually and seasonally (summer and winter). Data was missing from 1979 and 1993. Annual means could not be calculated for these years and winter and summer means could not be calculated for 1993 and 1994. Average Annual Mean Temperature ‐ Timmins
