July 2013 Global Temperature Anomalies

Headline:  "July 2013 Global combined land and water temperatures averaged the 6th highest on record".  

The global data set has 134 years of data (1880-2013). Scroll down past the map for a summary of the global May 2013 climate data.

Global Highlights (from NOAA/NCDC)

According to NOAA scientists, the globally averaged temperature for July 2013 was the sixth highest July since record keeping began in 1880. It also marked the 37th consecutive July and 341st consecutive month (more than 28 years) with a globally averaged temperature above the 20th century average. The last below-average July temperature was July 1976 and the last below-average temperature for any month was February 1985.
Many areas of the world experienced much warmer-than-average monthly temperatures, including northern South America, the western and northeastern United States, much of Africa, western and central Europe, parts of southern Asia, and most of Australia. Parts of the central and southeastern United States, small regions across northern Canada, eastern Greenland, and parts of Mongolia and eastern Siberia were cooler than average. Far northwestern Canada and part of the eastern United States were much cooler than their long-term averages.

Various National Highlights:

  • The national July temperature for Australia was 1.46°C (2.63°F) above the 1961–1990 average, marking the third warmest July since national records began in 1901. The July maximum temperature was the third highest at 1.52°C (2.74°) above average, while the minimum temperature was eighth highest. With the exception of Western Australia, every state and territory had an average July temperature that ranked among their seven highest on record. Tasmania reported a record high state-wide maximum temperature that was 1.28°C (2.30°F) higher than average, breaking the previous record set in 1950 and tied in 1993. No state or territory had maximum or minimum temperatures below their long-term averages.
  • New Zealand observed its fourth warmest July since national records began in 1909, with a temperature that was 1.2°C (2.2°F) higher than the 1971–2000 average. Many locations around Otago and Canterbury on the South Island had a record warm July.
  • Spain had its fifth warmest July since national records began in 1961, with a temperature that was 1.6°C (2.9°F) above the 1971–2000 average. The northern regions observed the highest anomalies, with some areas up to 3°C (5°F) above average.
  • It was the third warmest July across the United Kingdom since records began in 1910, at 1.9°C (3.4°F) above the 1981–2010 average. The "most notable heat wave since 2006" contributed to the warmth, according to the UK Met Office. Provisionally, it was the warmest July and second warmest month of any month on record (behind August 1995) for Northern Ireland.
  • With records dating back to 1767, Austria reported its second warmest July, tied with July 1983 and behind only 2006, with the nationally-averaged temperature 2.2°C (4.0°F) above the 1981–2010 average. Upper Austria and Salzburg each set new state maximum temperatures on July 28th.
  • The average July temperature across South Korea was the fourth warmest in the country's 41-year period of record, at 1.8°C (3.2°F) above the 1981–2010 average. The July minimum temperature was second highest on record for the month, at 2.1°C (3.8°F) above average.
  • July was warmer than average across nearly all of Japan. According to the Japan Meteorological Agency, Western Japan was significantly warmer than average, with a regionally-averaged July temperature that was 1.6°C (2.9°F) above the 1981–2010 average.
