Climate of 2009
June in Historical Perspective
National Climatic Data Center
16 July 2009


Global Highlights:

* Based on preliminary data, the globally averaged combined land and sea surface temperature was the second warmest on record for June and the January-June year-to-date tied with 2004 as the fifth warmest on record.

* Large portions of each inhabited continent were substantially warmer than average during June 2009. The warmest anomalies were most notable in parts of Africa and most of Eurasia. The most notable cooler-than-average temperatures were present from the southwestern U.S. to the Northern Plains, the Canadian Prairie Provinces, central Asia, and across the boundary of northeastern China and southeastern Russia.

* The most notable above-average precipitation during June 2009 was present across parts of central and northeastern Europe, eastern Asia, northern Brazil, and most of the northern half of the contiguous United States. The driest anomalies occurred across India, southeastern Asia, northern South America, southeastern and south central contiguous U.S., and parts of the western Pacific Islands.

* El Niño–Southern Oscillation (ENSO) transitioned from ENSO-neutral to El Niño conditions across the equatorial Pacific Ocean during June 2009. If El Niño conditions continue to mature as projected by NOAA, global temperatures are likely to continue to threaten previous record highs.
