Daily high (red) and low (blue) temperatures at our house for 2012. Click to celcify.
25ºF is about 75ºF, 35ºC is about 95ºF, and 0ºC = 32ºF (freezing).
You can clearly see in the chart above those few weeks in February when we were below freezing every day. That's a rare occurrence here. Also, our mild December weather after a chilly start is obvious on the extreme right-hand side. The arc is a trend line for the high (red) temperature.
I'd like a more automated way to do this, but the system I use works for now. The thermometer, at least, is electronic and has a console in the house with a sensor outdoors. The sensor does transmit, via radio signal, the temperature as it changes throughout the day. The console remembers the highest and lowest temperatures, but I do have to remember to reset it daily.
Monthly rainfall totals for 2012 at our house. Click to pluvioumetrate.
25.4 mm = 1 inch, so 731.5 mm is just under 29 inches of rain for the year.
The rain gauge is more simple. It's a plastic graduated cylinder that I have to read and empty by hand whenever there is rain. Snow is more problematic, but I've worked out my own method for that. You can see above that October was our wettest month last year, while August was quite parched (August was also our hottest month. How 'bout that!).
I've been tracking this data for seven years, so I have somewhat of a historic record. I'll spare you all of that.
Once a month, I transcribe the data from paper to an Excel spreadsheet (my years of university and career were good for something) and manipulate it into all manner of charts and graphs. Ain't retirement grand?
