NOAA's National Climatic Data Center (NCDC) late Thursday released its preliminary analysis of July 2009 global temperatures. It found that the global average land and ocean surface temperature was the 5th warmest on record, 0.57°C (1.03°F) above the 20th century average of 15.8°C (60.4°F). The ocean surface temperature broke the 1998 record to become the warmest for the month of July at 0.59°C (1.06°F) above the 20th century average of 16.4°C (61.5°F). The departure from the long-term average was equal to June's record amount. Other highlights from the NCDC report:
- July 2009 was the 33rd consecutive July with an average global land and ocean surface temperature above the 20th century average. The last July with global temperatures below the 20th century average occurred in 1976.
- The global land surface temperature for July 2009 was 0.51°C (0.92°F) above the 20th century average of 14.3°C (57.8°F), and tied with 2003 as the ninth-warmest July on record.
- For the year to date, the global combined land and ocean surface temperature of 14.3°C (57.9°F) tied with 2004 for the sixth-warmest January-through-July period on record.
