Southeast Queensland Chilled by Record-Breaking March Morning
Residents across southeast Queensland were met with a bracingly cool start to their Saturday, with several locations registering their coldest March mornings on record. The dramatic drop in temperature offered a stark contrast to the warmer days typically associated with this time of year, prompting widespread surprise and prompting meteorological explanations for the unseasonable chill.
Several weather stations across the region logged historic low temperatures, marking significant deviations from their usual March averages.
Amberley recorded a frigid minimum temperature of 6.2°C. This reading represents the coldest March temperature observed at Amberley in over 84 years of available records, a truly remarkable dip.
Toowoomba, known for its cooler climate, also experienced an exceptionally cold morning. The mercury fell to 8.1°C, a figure that hasn’t been seen in March for more than 29 years.
On the coast, the Gold Coast Seaway registered a minimum of 12.8°C. This marks the coldest March morning at this location in over 32 years, highlighting the widespread nature of the cold air mass.

Even the state capital, Brisbane, felt the bite of the unseasonal chill. The city’s temperature plummeted to 14.1°C, the coldest March morning recorded in 18 years. This was also the lowest temperature recorded in the River City since the early days of October, underscoring the significant shift in conditions.
The Science Behind the Sudden Chill
Meteorologists have pointed to a specific atmospheric event as the primary driver behind this record-breaking cold snap: a pronounced southwesterly change that swept through the region yesterday, 27 March 2026.
This shift in wind direction played a crucial role in ushering in a much drier air mass. The impact of this drier air was clearly evident in the significant drop in dew point. In Brisbane, for instance, the dew point fell dramatically from 15.8°C at midday to a remarkably low -2.4°C by 7pm. A lower dew point signifies less moisture in the atmosphere, which allows for more efficient radiative cooling overnight, leading to the colder temperatures observed.
The combination of clear skies, a lack of cloud cover to trap heat, and the dry air mass created ideal conditions for temperatures to plummet to historic lows across southeast Queensland.
A Fleeting Cold Spell
While the record-breaking temperatures provided a significant shock to the system, residents can expect a swift return to more typical March conditions. The current cold snap is predicted to be short-lived.
As the new week dawns, a shift in wind patterns is anticipated. East to southeasterly winds are set to return, bringing with them a more humid air mass. This will lead to higher dew points and, consequently, milder overnight temperatures. The unseasonably cold conditions are therefore expected to dissipate, allowing for a gradual return to the warmer, more familiar weather of late March.
