Outlook for the 2025/26 Season

The outlooks for 2025/26 seasonal determinations are based on historical flow records that have been adjusted to match climate conditions observed since 1975. The outlook scenarios presented are:

  • Wet                 Inflow volumes to major storages that are greater in 10 years out of 100
  • Average          Inflow volumes to major storages that are greater in 50 years out of 100
  • Dry                  Inflow volumes to major storages that are greater in 90 years out of 100
  • Extreme Dry   Inflow volumes to major storages that are greater in 99 years out of 100

The following tables summarise possible high-reliability water share seasonal determinations through the season and include a reference year to help users recognise the possible inflow conditions.
