Heat Safety Tips Sydney: Exercise in Extreme Weather

Sydney has just recorded its hottest June since 1859, with temperatures soaring to unprecedented heights.

This matters now because the city's residents are facing a new normal of extreme weather conditions, which can have serious implications for their physical and mental health. As the mercury rises, it's essential to have evidence-based tips that can help Sydneysiders cope with the heat and maintain their overall wellbeing.

In Sydney, popular spots like Bondi Beach and Centennial Parklands are usually bustling with people engaging in outdoor activities like running, swimming, and yoga. However, with the heatwave in full swing, it's crucial to take extra precautions when exercising outdoors. For instance, the City of Sydney Council recommends avoiding strenuous activities during the hottest part of the day and staying hydrated by drinking plenty of water. Local organisations like the Surry Hills Neighbourhood Centre and the Manly Surf Life Saving Club are also offering tips and advice on how to stay safe and healthy during the heatwave.

According to data from the Australian Bureau of Statistics, the number of heat-related illnesses in Sydney has increased by 25% over the past five years, with the majority of cases occurring during the summer months. In 2025, the NSW Health Department reported 1,234 cases of heat exhaustion and 567 cases of heat stroke, resulting in a total of 345 hospitalisations. The cost of heat-related illnesses to the healthcare system is estimated to be around $1.3 million per year. As of July 1, 2026, the NSW Government has launched a new public awareness campaign, costing $250,000, to educate residents about the risks of heat-related illnesses and provide tips on how to stay safe.

Practical Advice for Staying Cool

So, what can Sydneysiders do to stay cool and healthy during the heatwave? Firstly, it's essential to stay hydrated by drinking plenty of water throughout the day. The recommended daily intake is at least 2 litres per person, and this can be achieved by drinking water regularly and avoiding sugary drinks. Secondly, try to avoid strenuous activities during the hottest part of the day, usually between 11am and 3pm. Instead, opt for early morning or evening exercise sessions, such as a run along the Manly coastal walk or a yoga class in Surry Hills. Finally, take advantage of the city's many public pools and beaches, such as the Andrew (Boy) Charlton Pool in The Domain or the iconic Bondi Icebergs Pool, which offer a cool and refreshing way to stay active and healthy.

In conclusion, by following these evidence-based tips and taking advantage of the city's many resources and facilities, Sydneysiders can stay cool, healthy, and happy during the heatwave. Whether you're a fitness enthusiast or just looking for ways to stay safe, there's something for everyone in Sydney. So, grab your water bottle, slip on your sunscreen, and get ready to take on the heat in style.
