Maryborough Hailstorm October 2nd 2025: 8cm Hail and Record Lightning Activity Devastate Wide Bay Region
On Thursday afternoon, October 2nd, 2025, Maryborough and the broader Wide Bay region experienced one of the most intense severe weather events in recent Queensland history. Giant hailstones reaching 8 centimeters in diameter combined with extraordinary lightning activity - over 204,000 strikes in nine hours - created a devastating natural disaster that impacted communities across the Burnett and Wide Bay forecast districts.

A Destructive Storm Brewed in Hours
October 2nd, 2025, will be remembered as a defining day in Queensland's severe weather history. What began as developing cumulus clouds near Childers around late morning rapidly evolved into one of the most destructive hailstorms to impact the Wide Bay and Burnett regions in decades. The convergence of atmospheric conditions created the perfect environment for explosive thunderstorm development, resulting in giant hailstones and record-breaking lightning activity that left communities reeling.
The Bureau of Meteorology issued severe thunderstorm warnings as the system intensified throughout the afternoon, but the sheer scale and intensity of the event exceeded even the most concerning forecasts. By evening, damage assessment teams were documenting widespread destruction across multiple communities, with Maryborough bearing the brunt of the most severe impacts.
The Perfect Storm: Atmospheric Setup
The October 2nd event was the result of a textbook severe weather scenario that meteorologists describe as ideal for supercell thunderstorm development. An upper trough moving into southern Queensland combined with warm and humid surface conditions and significantly colder temperatures aloft - a combination that primed the region for explosive convective activity.
Surface temperatures across the Wide Bay region reached the mid-to-high 20s Celsius, while upper-level temperatures plummeted well below freezing. This extreme temperature differential, known as atmospheric instability, provided the energy necessary for the violent updrafts that would eventually produce the giant hailstones that devastated the region.
Weather Map (Swathe Data)
Rapid Storm Development: From Clouds to Catastrophe
Satellite imagery captured the remarkable speed of storm development on October 2nd, providing a minute-by-minute record of how quickly conditions deteriorated. Late morning cumulus clouds with cloud top heights of just over 1,500 meters exploded upwards to nearly 10,000 meters near Childers within approximately 30 minutes - a rate of vertical development that indicates extreme atmospheric instability.
This rapid vertical development is characteristic of supercell thunderstorms, which are capable of producing the most severe weather phenomena including giant hail, destructive winds, and intense rainfall. The speed of development left little time for residents to prepare, highlighting the importance of early warning systems and rapid response protocols.
Hailstone Data and Distribution
The hailstorm produced some of the largest hailstones recorded in Queensland during 2025, with systematic damage assessment revealing the following distribution:
Maximum Hail Size: 8 centimeters diameter (approximately the size of a tennis ball)
Tinana Impacts: 8cm hailstones reported with extensive property damage
Oakhurst Impacts: 5cm hailstones causing significant vehicle and roof damage
Maryborough Central: Variable hail sizes from 3-6cm causing widespread damage to residential and commercial properties
Duration: Hail lasted approximately 15-20 minutes in the most severely affected areas
Path Width: The hail swath extended across multiple suburbs and surrounding rural areas
The 8cm hailstones represent some of the largest ever recorded in the Wide Bay region, with the size classification putting them in the 'giant hail' category that poses extreme danger to people, property, and vehicles.
Lightning Activity: Unprecedented Electrical Display
Perhaps the most remarkable aspect of the October 2nd storm was the extraordinary lightning activity that accompanied the hailfall. Weather monitoring stations recorded truly unprecedented electrical activity:
Total Lightning Strikes: 204,734 strikes within 200 kilometers of Hervey Bay
Duration: Nine-hour period from 12:30 PM to 9:30 PM AEST
Ground Strikes: 25,050 cloud-to-ground lightning strikes
Peak Activity: Concentrated during the afternoon and early evening hours
Geographic Spread: Lightning activity extended well beyond the hail core, affecting a much broader area
To put this lightning activity in perspective, the 204,734 strikes recorded in a single day represent more electrical activity than many regions experience in an entire storm season. The density of lightning strikes posed significant risks to emergency responders, aviation, and outdoor workers across the region.
