May global temperatures cooled considerably below the record warmth experienced in 1998 but continued to be well above average in May. Based on a long term mean (1880-1998), May 1999 land and ocean temperatures were more than 0.3 C above average, nearly 0.4 C less than the record global temperature recorded in 1998.

Precipitation on the global land surface was below average in May. Based on a 1900 to 1998 long term mean, global precipitation was less than 2.5 mm below average in May. See the Global Analysis and Global Regional Analyses pages for more details on the global climate. Global Land Precip, May
