Climate Anomaly Viewer

The Climate Anomaly Viewer allows users to explore monthly temperature and precipitation anomalies in British Columbia, since 1970, using data drawn from the Provincial Climate Data Set (PCDS)

The difference between “the weather you expect” and the “weather you get” is a critical link between people and climate. The normal, or expected, weather conditions for a month or season is known as the climatology, and is a key characteristic of a given locale. A simple and intuitive way to discover how different observed conditions are from normal is to depict the departure of average temperature and total precipitation from the long term climatology at observational weather stations.

The maps in the Climate Anomaly Viewer display monthly anomalies at meteorological station locations across BC, relative to their 30-year climatological values.

With the Climate Anomaly Viewer, users can:

  • View historical temperature and precipitation anomalies by month from 1970 to present
  • Examine baseline (1971-2000) temperature and precipitation averages for locations across BC
  • Explore if and how specific monthly anomalies relate to observed climate impacts

Please note that the map only shows stations where there is both a 71-00 baseline and a valid monthly aggregate at the exact same location; therefore, for some variables and locations, outputs can be sparse. 

Intended users

 The Climate Anomaly Viewer is intended for general use by a wide audience.
