Difference between daily mean temperature and the 30-year average mean temperature

90 day temperature anomaly

Plot updated 1969-12-31 14:00:00

The plot shows how much warmer or colder than normal each day in the time period was than the temperature in an average year. Lines that extend above the zero line indicate that day was warmer than normal, and lines below the horizontal indicate a day that was colder than normal.

Verticle lines represent the temperature anomaly for that date. The horizontal orange lines show the average anomaly for the interval shown.
