The agency uses climate locations all over the globe, on land, and across the ocean, to come up with a monthly report of how the respective month turned out compared to climate data. Of course as Mark Twain simply put it, "Climate is what we expect, weather is what we get."
It was the warmest May on record for Earth since records began in the late 1800's! That's impressive to say, plus it continues a trend that has yielded the warmest Mays in the past several years. Africa, Australia, Europe, and Alaska were some of the broad land masses that had top ten warmest Mays, plus the warm ocean temperatures put the overall global temperature at its record number.
Overall the average temperature was about 60 degrees when factoring all the locations and dates, above the 20th century average by about 1.0 to 1.5F. You can read the full report at the following website: http://www.ncdc.noaa.gov/sotc/global/2014/5
Locally the weather resulted in similar numbers, many towns about one to two degrees warmer than average for May 2014 with exception to St. Johnsbury, VT just a tad cool. The region also saw slightly wetter conditions by about an inch or less, so pretty common numbers.
June is about to wrap up, which is warm and wet so far by a couple of inches and couple of degrees.
