Something I’ve noticed about the weather

In the office we have been monitoring and recording temperatures for just over 5 years. As you can see from the data below, there were some problems originally setting up the server to record the data but as of about august 2002 we have been quite reliable.

With all these people talking about global warming etc, I think I’ve found a trend that may have escaped other peoples notice. If you look at the graph below you will probably notice what I did. It seems to get warmer towards the end of the year and colder again in the middle.

I know this is only 5 years worth of data but it seems pretty clear to me that there is a definite pattern emerging. Of course I’ve been wrong in the past. Click on the image for a larger version if you need more detail.tempratures
