- Global average combined land and sea surface temperature in
2002 was the second warmest on record for July
- July temperatures were 3-5°C (5.4-9°F) warmer than
average over much of eastern Europe and western Russia, as well as
parts of the western U.S.
- Above average precipitation during July occurred across the
islands of the western Pacific, including Japan and parts of
southeast China, with much drier conditions across India, parts of
Australia and the U.S.

data set of land
surface stations using a 1961-1990 base period also show the
warmer than average temperatures across much of the United States,
and across a large area from Scandinavia southward into north
Africa. Cooler than average temperatures were observed over much of
Argentina and parts of Australia.
- For July 2002, the global average land and ocean surface
temperature was 0.49°C (0.88°F) above the 1880-2001
average, ranking as the second warmest July in the period of

- The July land surface temperature average was second warmest on
record, 0.82°C (1.48°F) above average
- Globally averaged ocean surface tempeatures were 0.35°C
(0.63°F) above the 1880-2001 mean, or fourth warmest
- The global land and ocean surface temperature average
(January-July 2002) was the second warmest such 7-month period in
the 1880-2002 record, 0.62°C (1.12°F) above the long-term
mean and 0.06°C (0.11°F) cooler than during the El
Niño year of 1998
- Year to date average temperature across land areas
ranks as warmest on record for the 7-month period from January-July
2002, or 1.10°C (1.98°F) above the 1880-2001 average
- Serial monthly global surface temperature departures with
respect to a 1971-2000 mean are shown in the figure to the
- The recent return to record or near record temperature
departures is evident, and globally averaged surface temperatures
(land and ocean) have been warmer than the 1971-2000 average for
the last 75 consecutive months
- During July 2002, much above average precipitation fell across
the western Pacific, including southeast China, the Philippines and
Japan as a number of tropical storms and typhoons affected the
- Other areas of above average precipitation were noted over
western Europe and the Mediterranean
- Monsoon rains were much lighter than average over India, while
drier conditions were also observed over parts of the United States
and most of Australia
