I like to track weather and climate data. Though my instruments are non-precision they help me track daily high and low temperature, rainfall, and snowfall. I write the numbers on the calendar then transfer them to a spreadsheet, in which I keep the data in tabular and graphical form. It’s a cool way to see what happens during the month, year, and over the years since I have lived in Dresden. It’s also neat to compare against climate data collected here by Environment Canada during the years 1971-2000.
Here is the graph for January through yesterday morning. The red line is the high, the roughly corresponding line is the low, green = rain and lighted blue = snow. Up and down the temperatures have gone. Despite that big dip our average low of -6 is three degrees warmer than the historic average of -9. Another big dip looms in the next few days, which should bring that average low more in line with the historic data. The green spike is a day of rain, and we have already exceeded the average snowfall by a comfortable margin.
