Credit: NOAA -

According to NOAA scientists, the average temperature for the contiguous U.S. during September was 67.0°F, 1.4°F above the long-term average, tying September 1980 as the 23rd warmest such month on record. September 2012 marks the 16th consecutive month with above average temperatures for the Lower 48.

The September nationally averaged precipitation total of 2.40 inches was slightly below the long-term average. The Northern Plains, Northern Rockies, and Northwest were record and near-record dry for the month. This dryness helped fuel wildfires in the West, where nearly 1.1 million acres burned during September, the 3rd most on record for the month. Much above-average precipitation was observed in the Ohio Valley. As of October 2, 64.6 percent of the contiguous U.S. continued to experience drought conditions.

NCDC’s monthly climate analysis (summary, full report) is part of the suite of climate services NOAA provides government, business, and community leaders so they can make informed decisions.
