Climate outlook

Map of Ord region showing the spatial distribution of the chance of exceeding median rainfall in percentage categories for December 2021–February 2022. Rainfall has a greater than 60% chance of exceeding median rainfall during December 2021–February 2022 across the region and a greater than 70% chance of exceeding median rainfall across the entire southern half of the region upstream of Lake Argyle. Key aspects of the rainfall map are described in the text below the figure.

  • The next few months (December–February) are usually when about two thirds of the region's annual rainfall occurs. According to the Bureau of Meteorology's climate outlook (25 November 2021), rainfall is expected to be average during this period.
  • The El Niño–Southern Oscillation (ENSO) is currently in a La Niña phase. However, this La Niña is likely to be short-lived, persisting only until the late summer or early autumn 2022.
  • Inflows into the region's storages for the 2021–22 year are expected to be average and less than 2020–21.


Future commitments

  • Water use is expected to be more than 2020–21, primarily due to the likely average rainfall conditions.
