Our mission is to provide accurate global weather forecasting that empowers people to prepare for the challenges of tomorrow. We believe that being forewarned is being forearmed, and by delivering trusted weather intelligence ahead of extreme weather events, we help protect lives, strengthen communities, safeguard businesses, and support informed decisions worldwide.
For Hayden Walker, weather has always been more than a forecast. It is a lifelong passion, a family legacy, and a commitment to helping people prepare for whatever nature has in store.
As Australia’s fourth generation of long range weather forecasters, Hayden proudly continues a forecasting tradition spanning more than 130 years. Following in the footsteps of renowned weather pioneers including Clement Wragge, Inigo Jones and his father, Lennox Walker, Hayden combines generations of forecasting knowledge with decades of personal observation to deliver trusted long range weather intelligence across Australia and around the world.
From an early age, Hayden learned that successful forecasting is about understanding patterns rather than simply reading computer models. By studying historical weather cycles, solar activity and atmospheric behaviour, he has developed a forecasting approach that helps businesses, emergency services and communities prepare well before severe weather develops.
Hayden has earned a reputation for accurately predicting significant weather events, including major cyclones, flooding and severe storm outbreaks. His long range forecasts are relied upon by industries including agriculture, mining, construction, insurance, transport and event management, helping organisations minimise risk, protect assets and make informed decisions.
Beyond forecasting, Hayden has become a respected media commentator, sharing his expertise through television appearances and regular interviews on radio stations including 4BC, 2SM and 2GB. His ability to explain complex weather systems in a practical and easy-to-understand way has made him a trusted voice for listeners wanting to understand all facets of the weather, particularly what lies ahead to eliminate risk.
At the heart of Extreme Global Weather is one simple belief. When people have accurate weather intelligence, they can make better decisions. Whether helping a business protect its operations, supporting emergency planning, or giving families time to prepare for severe weather, Hayden’s goal remains the same: to provide trusted forecasts that help people stay one step ahead of extreme weather.

The Evolution of Weather Forecasting for thousands of years, people have looked to the sky in search of answers. Long before satellites, computers, and radars existed. Farmers, sailors and explorers relied on the behaviour of clouds, birds, wind direction and even the colour of the sunrise to predict changing weather conditions. These observations often meant the difference between successful harvesting or safe voyages across the ocean. As science advanced, so did our understanding of the atmosphere. The invention of the barometer in the 1700s allowed people to measure changes in air pressure, while the thermometer and rain gauge provided more accurate weather observations. By the late 1800s, the telegraph enabled weather information to be shared over great distances for the first time, laying the foundations for modern forecasting. The twentieth century transformed meteorology. Weather balloons, aircraft observations, radar and eventually satellites gave forecasters an entirely new perspective of our atmosphere. Powerful computer models now process billions of calculations every day, helping meteorologists understand how weather systems are developing across the globe. Yet despite incredible advances in technology, forecasting remains as much about understanding patterns as it is about processing data. Long-range forecasting combines science, experience, historical weather records, climate cycles and atmospheric analyses to identify trends that may develop weeks or even months into the future. Today, weather forecasting has become an essential part of everyday life. It helps protect communities from severe weather, supports emergency services, guides aviation and marine operations, assists farmers in managing crops, and enables businesses to make informed decisions that reduce risk and protect their people. At Extreme Global Weather, forecasting is about more than simply predicting tomorrow's conditions. It is about understanding the bigger picture, recognising long-term weather patterns, and providing the knowledge people need to prepare for what lies ahead.
