Although we are a few days away from the end of the month, it is likely that the 12 month period which began at the start of July 2011 to the end of June 2012 will go down as the warmest in the almost 100 years of recorded weather data in the region.
Until recently the warmest 12 month period in the region happened to be the calendar year of 1998 when the average temperature was 8.98 degrees. The last 12 months will be around 9.30 degrees depending on how these last few days play out. By the way the 1971-2000 average annual temperature is 6.7 degrees.
With the warm winter we had, combined with the record breaking extremely hot March puts the average for the July 2011 to June 2012 period at 9.30 degrees. This solidly beats the old record.
The last time we had a colder than average month was back in March of 2011.
