So just how hot is it in Austin, really?

After some controversy over just how bad the weather gets in Austin, I decided to go pick up some actual historical data from the NOAA web site. First, the monthly averages, in turn averaged for 1931-2000: City <td> Jan </td> <td> Feb </td> <td> Mar </td> <td> Apr </td> <td> May </td> <td> Jun </td> <td> Jul </td> <td> Aug </td> <td> Sep </td> <td> Oct </td> <td> Nov </td> <td> Dec </td> Austin TX <td> 52.
