Difference between daily mean temperature and the 30-year average mean temperature for the past twelve months

[PDF version (80 Kb)]

The plot shows how much warmer or colder than normal each day in the time period was compared with the temperature on that date in an average year. Dates in blue are colder than normal, and those in red are warmer.

Note that these anomalies aren’t scaled, so winter anomalies will be larger than those in the summer. A normalized plot is also available.
