Heat Risk Analysis
Thomson in Victoria faces location-specific extreme heat risk. The Bureau of Meteorology (BOM) reports that Australia's average temperature has increased by approximately 1.5 °C since 1910, with the frequency of extreme heat days rising across most regions.
The urban heat island (UHI) effect can make built-up areas of Thomson warmer than surrounding rural areas, particularly on summer nights. Dark roof materials, limited tree canopy cover, and heat-absorbing surfaces contribute to localised heat stress that varies by property.
Projected to increase significantly, with more frequent days over 40°C.
Get an address-level heat risk assessment from ClimateNest for Thomson including cooling cost estimates, heatwave vulnerability scoring, and adaptation recommendations tailored to your property.
ClimateNest assesses hazards at the address rather than the suburb, because exposure varies street by street within Thomson. An address-level check is what tells you about a specific property before you buy, sell or insure it.
Local Hazard Evidence
Historical Events
A prolonged period of extreme heat affected Victoria, including the Geelong region, leading to increased demand on power grids and health services.
Victoria experienced a severe heatwave, with record-breaking temperatures causing widespread health impacts and infrastructure strain. Thomson would have been affected.

Frequently Asked Questions
How hot does Thomson get in summer?
Thomson in Victoria experiences summer temperatures consistent with the regional climate. BOM publishes historical temperature data for weather stations near Thomson. Get a property-specific heat exposure assessment with projected cooling costs from ClimateNest.
Is extreme heat increasing in Thomson?
Australia-wide, extreme heat events have become more frequent since the mid-20th century, and this trend is consistent with CSIRO climate projections for Victoria. Continued warming is likely through 2050 under all emissions scenarios.
How does heat affect energy costs for Thomson properties?
Higher temperatures increase cooling demand, which raises electricity costs. ClimateNest provides energy cost projections based on your property's specific exposure to extreme heat days in Thomson and the performance of your building envelope.
What heat mitigation measures work best in Thomson?
Effective heat mitigation includes light-coloured roofing (cool roofs), ceiling and wall insulation, double-glazed windows, external shading, cross-ventilation design, and increasing tree canopy around the property. These measures reduce indoor temperatures and cooling costs.
