Regional predictions


Changes in temperature and rainfall

Changes in average temperature in Devonport are projected to range from 0.2-1.0C, the least of all the regions studied. Extreme temperatures are still not expected to exceed 40°C.  Annual rainfall is expected to decline by 1-11%, with the main decrease in spring, where rainfall could decline by up to 17%.

Potential effects on crops

  • Devonport appears to be the least affected of the regions studied by projected climate changes
  • Small increases in monthly minimum and maximum temperatures will add to what is already a mild climate
  • The Devonport region relies on river extraction as well as surface water for irrigation during summer. Projected declines in spring rainfall will increase irrigation requirements.

Note : These descriptions relate to the temperatures that the crops experience and not to changes in monthly average temperatures. An increase of 1oC in monthly average temperature can easily mean increases of 4oC or more on particular days.
