Preliminary Data Shows June 2009 Second Warmest on Record Globally; Global Sea Surface Temperature Hits June Record
Based on preliminary data, the globally averaged combined land and sea surface temperature was the second warmest on record for June 2009 and the January-June 2009 year-to-date tied with 2004 as the fifth warmest on record, according to the US National Climatic Data Center (NCDC), part of NOAA (National Oceanic and Atmospheric Administration).

Sea surface temperatures during June 2009 were warmer than average across much of the world’s oceans, with the exception of cooler-than-average conditions across the southern oceans. The global ocean SST for June 2009 was the warmest on record, 0.59 °C (1.06 °F) above the 20th century average of 16.4 °C (61.5 °F). This broke the previous June record set in 2005.
Large portions of each inhabited continent were substantially warmer than average during June 2009. The warmest anomalies most notable in parts of Africa and most of Eurasia, with temperatures of 3°C (5°F) or more above average.
The most notable cooler-than-average temperatures were present from the southwestern US 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 US, 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.
