Land surface temperatures were 1.39 Fahrenheit degrees above average, making it the 11th-warmest August on record, while the global sea surface temperature was 1.03 degrees Fahrenheit above average, tying with 1998, 2003, 2005, and 2009 as the record-highest for August.

FRISCO — Despite the near absence of record heat across the contiguous 48 states, the summer of 2013 (June-August) ranked as the eighth-warmest on record, with an average temperature of 72.6 degrees, about 1.2 degrees warmer than the 20th century norm.
The data tallied by the National Climatic Data Center suggests an era of new normals, with temperatures running well above historic averages even in non-El Niño years. Taken separately, August 2013 was the 28th-warmest on record with an average temperature of 73..1 degrees, 1 degree above the 20th century average. Read the full report here.
FRISCO — The global temperature for July 2013 was 1.10 degrees (all temperatures in Fahrenheit) above the 20th century average, making it the sixth-warmest July on record, according to the National Climatic Data Center.
Nearly every part of Earth reported temperatures well above average with the exception of a few pockets, notably the southeastern and central U.S. and parts of India.
Climate experts outline weather extremes across the U.S.
By Bob Berwyn
After years of persistent drought across big swaths of contiguous 48 states, the weather picture changed dramatically in 2012. Instead of dealing with parched ground, farmers in the Southeast weren’t able to harvest crops this summer because of standing water in the fields.
Mold and fungal diseases were reported across the region, particularly on crops such as corn, tomatoes and peanuts. The excess moisture has degraded the quality and flavor of many crops, including watermelons, tobacco, and peaches. Flooded soil has hampered the growth of cotton and corn, with damage from excess moisture expected to cost billions, The National Climatic Data Center reported this week in its July update.

Record moisture in Florida, record dryness in Oregon

FRISCO — Although a big slice of the south-central and southeastern U.S. reported cooler-than-average temperatures in July, the contiguous 48 states as a whole were once again warmer than the 20th century average.
Strongest climate signals coming from Arctic and extreme weather events
By Bob Berwyn
FRISCO — Some of the most compelling signs of global warming impacts continued to come from the Arctic in 2012, where sea ice extent reached a record low and Greenland experienced record surface melting last summer.
Another worrying sign is the warming in permafrost regions, where significant thawing could release a new surge of heat-trapping greenhouse gases that would intensify warming.
