Note: The data presented in this report are preliminary. Ranks and anomalies may change as more complete data are received and processed. Effective September 2012, the GHCN-M version 3.2.0 dataset of monthly mean temperature replaced the GHCN-M version 3.1.0 monthly mean temperature dataset. Beginning with the August 2012 Global monthly State of the Climate Report, released on September 17, 2012, GHCN-M version 3.2.0 is used for NCDC climate monitoring activities, including calculation of global land surface temperature anomalies and trends. For more information about this newest version, please see the GHCN-M version 3.2.0 Technical Report.
*The GHCN-M version 3.1.0 Technical Report was revised on September 5, 2012 to accurately reflect the changes incorporated in that version. Previously that report incorrectly included discussion of changes to the Pairwise Homogeneity Algorithm (PHA). Changes to the PHA are included in version 3.2.0 and described in the version 3.2.0 Technical Report. Please see the Frequently Asked Questions to learn more about this update.
- Global average combined land and sea surface temperature was
the third warmest for January 2003
- Temperatures were much above average across western U.S,
Alaska, Canada and southeast Australia with below average
temperatures across eastern U.S., eastern Mongolia and
- Precipitation during January was above average across much of
Europe and northern Africa as well as parts of southeast China,
with drier than average conditions over northern Brazil, most of
the U.S. and the eastern half of Australia

anomalies calculated from the Global Historical Climatology Network
data set of land surface stations using a 1961-1990 base period
also show above average temperatures throughout Canada, Alaska and
much of the western United States. Monthly temperatures were
4-6°C (7.2-10.8°F) above the mean. Notable cool anomalies
were present throughout the eastern U.S., northern Europe, and
parts of southern Asia where monthly temperatures were as much as
3-6°C (5.4-10.8°F) below average.
- For January 2003, the global average land and ocean surface
temperature was 0.60°C (1.08°F) above the 1880-2002
average, ranking as the third warmest January in the period of
- The warmest January occurred in 2002, with an anomaly of
- Globally averaged land temperatures were second warmest on
record, or 1.03°C (1.85°F) above the long-term mean
- January 2003 temperatures averaged across the Northern
Hemisphere were third warmest on record, or 0.68°C (1.22°F)
above the long term mean
- Temperatures averaged throughout the Southern Hemisphere were
fourth warmest, or 0.53°C (0.95°F) above average
- During January 2003, much above average precipitation fell
across most of Europe into northern Africa, as well as southern
Brazil and parts of southeast China
- Below average precipitation was observed across most of the
U.S., the eastern half of Australia and northern Brazil
