The record setting warmth from this summer has continued into the fall. September 2007 will go down in the record books as one of the hottest Septembers on record in the Triangle. At RDU, last month was the second warmest September in the record books. To compare months, we use the monthly average temperature, which was 75.0 last month.
Here's a look at the warmest Septembers recorded at RDU --
1. September 2005 -- 76.0
2. September 2007 -- 75.0
3. September 1980 -- 74.9
4. September 1954 -- 74.9
5. September 1998 -- 74.6
The all time hottest September in the Triangle was in 1921 when the monthly average temperature was 78.5. Weather records were not kept at RDU at that time, since RDU was not built until the 1940s.
