Climate change impacts in Southern Tasmania

The impacts of climate change will vary across southern Tasmania’s local government areas and be experienced by communities as changes to their local weather conditions.

Through the Climate Futures for Tasmania Tasmanian councils are fortunate to have access to the highest resolution climate modelling conducted worldwide.

Based on its climate modelling work, CFT has partnered with the STCA to develop climate scenarios for the Southern Tasmanian region •••••• to regional climate profile and 12 individual local government areas. •••••• to municipal climate profile

The climate impact scenarios provide a sound knowledge base for identifying localised climate related risks and subsequently in informing appropriate decisions to manage the risks.

The fine scale CFT scenarios show that climate change impacts in southern Tasmania are typically predicted to affect the frequency, intensity and duration of features of our climate such as temperature and rainfall.

Overall for the southern region the scenarios predict that there will be:

  • increases in the number of summer days particularly in the Derwent Valley and the East Coast areas
  • an increase in annual temperature of 3C experienced in the west coast of the southern region, the Derwent Valley, Huon and Central Highlands municipalities
  • increase in the heat waves (3 or more days above 28°C) in the Derwent Valley area
  • an overall increase in warm spells across the southern region
  • moderate increases in rainfall in the East Coast, Tasman and Greater Hobart areas
  • decreases by 6 – 10% in rainfall in the northern Central highlands area
  • changes as in the seasonality of the rainfall with the inland areas of the southern region experiencing higher rainfall over winter and lower rainfall throughout summer and the northern Central Highlands experiencing decreased rainfall in all seasons
