Western Australia (WA), renowned for its vast landscapes and sun-drenched climate, is no stranger to extreme heat. This state, which encompasses a third of the Australian continent, experiences some of the highest temperatures recorded in the country. But what is the hottest temperature ever recorded in Western Australia, and what factors contribute to such intense heat? Let’s dive into the details, explore the record-breaking temperatures, and uncover how WA’s unique geography plays a role in its scorching climate.
The Hottest Temperature Ever Recorded in Western Australia
The highest temperature ever recorded in Western Australia is 50.7°C (123.3°F), observed in Onslow on 13 January 2022. This staggering temperature tied the record for the hottest day ever documented in Australia, previously set in Oodnadatta, South Australia, in 1960.
Where is Onslow?
Onslow is a small coastal town in WA’s Pilbara region, known for its extreme climate and proximity to mining operations. The Pilbara is famous for its searing summer heat, making it one of the hottest regions in Australia.

Why Is Western Australia So Hot?
Western Australia’s extreme temperatures can be attributed to several geographical and climatic factors:
1. Vast Size and Geography
Western Australia is enormous, covering over 2.5 million square kilometers. Its inland regions, especially in the Pilbara and Kimberley, are arid or semi-arid, with little vegetation to moderate temperatures. These areas absorb intense heat during the day, creating sweltering conditions.
2. High-Pressure Systems
During summer, high-pressure systems dominate WA’s weather, leading to prolonged heatwaves. These systems trap heat and suppress cloud formation, resulting in clear skies and intense solar radiation.
3. Proximity to the Tropics
Northern WA lies close to the Tropic of Capricorn, placing it in a tropical climate zone. This leads to higher temperatures, particularly in the summer months.
How Does WA’s Heat Compare Globally?
Western Australia’s hottest days rank among some of the highest temperatures recorded globally. For context:
- Death Valley, USA: Holds the world record at 56.7°C (134°F).
- Kebili, Tunisia: Recorded 55°C (131°F).
- Onslow, WA: At 50.7°C (123.3°F), it is among the hottest temperatures recorded in the Southern Hemisphere.
Seasonal Temperature Trends in Western Australia
Summer (December to February)
- Average Temperatures: Coastal areas like Perth range from 30°C to 35°C (86°F to 95°F), while inland regions, including the Pilbara, frequently exceed 40°C (104°F).
- Heatwaves: Prolonged periods of extreme heat are common, especially in the northern and interior regions.
Winter (June to August)
- Average Temperatures: Coastal areas experience mild winters, with Perth averaging 18°C to 21°C (64°F to 70°F). Inland areas see cooler nights but remain relatively warm during the day.
- Dry Season in the North: Regions like Broome and the Kimberley enjoy sunny, pleasant conditions.
Regions Known for Extreme Heat in WA
1. The Pilbara
The Pilbara region is infamous for its blistering summers. Towns like Marble Bar, often referred to as the “hottest town in Australia,” regularly experience temperatures exceeding 45°C (113°F).
Fun Fact:
Marble Bar holds the record for 161 consecutive days of temperatures above 37.8°C (100°F), set between October 1923 and April 1924.
2. The Kimberley
While slightly more humid than the Pilbara, the Kimberley region also sees high temperatures, particularly in its inland areas.
3. The Goldfields
Kalgoorlie and surrounding areas in the Goldfields region are known for their hot, dry summers, with temperatures frequently hitting the high 30s or low 40s Celsius.
Adapting to the Heat: Survival Tips
Living or traveling in Western Australia during its hottest months requires preparation. Here are some essential tips:
1. Stay Hydrated
- Carry a reusable water bottle and drink water regularly.
- Avoid caffeinated or alcoholic beverages, which can dehydrate you.
2. Wear Appropriate Clothing
- Opt for lightweight, breathable fabrics like cotton or linen.
- Wear wide-brimmed hats, sunglasses, and sunscreen to protect against the sun.
3. Limit Outdoor Activities
- Schedule outdoor activities for early mornings or evenings when temperatures are cooler.
- Avoid strenuous physical activity during peak heat.
4. Seek Shade or Air Conditioning
- Spend time indoors during the hottest parts of the day (12 PM to 3 PM).
- Use fans or air conditioning to stay cool.
5. Check Weather Warnings
- Stay updated with local forecasts and heatwave warnings from the Bureau of Meteorology.
The Impact of Rising Temperatures
Climate change has amplified the frequency and intensity of heatwaves in Western Australia. According to meteorological data, WA’s average temperatures have risen significantly over the past century. This warming trend is likely to continue, posing challenges for agriculture, infrastructure, and public health.
