Townsville Officials, Experts and Community Leaders React to Hottest Start to Winter on RecordUpdated

Townsville authorities are urging residents to prepare for an unusually warm and dry winter, after June 2026 delivered record-breaking temperatures that saw the city’s average maximum soar to 30.2°C, the hottest start to winter in more than a century.

For a city still grappling with the legacies of the 2019 floods and ongoing concerns over Ross River Dam levels, the new heatwave record has put climate adaptation and water security back into sharp focus for officials and service providers.

Local Concerns Centre on Water, Energy and Vulnerable Residents

The Townsville Local Disaster Management Group met this week at the Thuringowa Centre on Riverway Drive to discuss contingency plans. Council’s Water and Waste Committee chair Cr. Mark Molachino pointed to below-average dam inflows and rising household consumption across Douglas, Cranbrook and Mount Louisa. "The Ross River Dam is sitting at just 59.5% capacity as of July 3," Molachino said in a statement released Thursday. Townsville City Council is fast-tracking partnership talks with Sunwater and the Burdekin River Irrigation Scheme to bolster supply through the dry season.

Key voices at James Cook University’s Tropical Institute of Sustainability warned the city could see rolling water restrictions if the trend continues. Dr. Gemma Unsworth, a climate impacts researcher, cited newly released Bureau of Meteorology data showing Townsville’s rainfall for June was only 2.1mm-about 7% of the city’s long-term average. "We are advising Council and the hospital network to reinforce cooling strategies for at-risk groups, especially the elderly and those in public housing along Flinders Street and Heatley," Unsworth noted in a briefing to stakeholders on Wednesday.

Climate Data and Economic Resilience on the Agenda

Townsville Enterprise CEO Claudia Brumme-Smith said the temperature record is already pushing up local power bills. “Ergon Energy’s figures show residential electricity use for June jumped by 18% in Townsville compared to last year, putting pressure on low-income families in Aitkenvale and Railway Estate,” she said. The city’s economic anchor institutions-including the Lavarack Barracks and Queensland Nickel Industries-have both advised employees to adopt heat stress protocols as a precaution.

Debate is also intensifying around the city’s hydrogen hub ambitions. On July 1, Queensland Treasurer Cameron Dick referenced Townsville’s hydrogen precinct at Cleveland Bay in state parliament, saying, "The need for climate solutions is not theoretical here, it’s a direct response to what we’re seeing on the ground in north Queensland." The long-term forecast from the CSIRO suggests Townsville could see a further 0.7°C rise in annual average temperatures by 2035 if emissions trends persist.

The next key decision for local residents could come as soon as July 16, when Council will hold a public forum at the Perc Tucker Regional Gallery on Mitchell Street to discuss potential level one restrictions and urban cooling initiatives. For now, authorities are urging households to check irrigation timers, avoid watering during peak evaporation (11am-3pm), and take advantage of Council’s free mulch program at the Bohle Waste Facility.
