It was a wet one for Tasmanians, especially for those in the north, as the state endured its wettest summer since 2010.
It was a summer for raincoats and umbrellas as the state received 19 per cent more rainfall than average over the summer period, with the wettest day belonging to Mathinna with 125 millimetres on December 21.

Dr Andrew Marshall, senior research scientist at the Bureau of Meteorology, said the state rainfall was the highest in 10 years.
"Tasmania has just had its wettest summer in 10 years. Rainfall was above average across the north and close to average elsewhere, making it Tasmania's highest summer rainfall in 10 years," he said.
"Northern Tasmania's wet summer is typically what we expect under the influence of a La Nina event in the tropical pacific, which has been active over the last few months."
Dr Marshall confirmed that La Nina had also been a factor when the previous wettest summer for Tasmania was recorded in 2010-11.
As expected with the highest rainfall in a decade, some sites broke their summer day records in 2020-21 including Liawenee and Mount Dromedary.
"A few sites had their wettest summer day on record on February 6, when a complex low pressure system, cold front and pre-frontal trough tracked over Tasmania," Dr Marshall said.
However, it was not all rain and gloom for Tasmania as temperatures soared at Dover to 38 degrees on January 11 - the state's hottest summer day.
Another record tumbled when Bicheno recorded the warmest summer night on record at 19.5 degrees on February 19. Bicheno entered the record books again for their highest average nighttime temperature at 14.2 degrees.
Dr Marshall warned that while La Nina was past its peak, it would continue to influence the weather in the coming months.
"The La Nina event has now passed its peak and is weakening ... La Nina is expected to continue to influence above average rainfall ... including parts of Tasmania as it weakens in the autumn," he said.
"Under the influence of La Nina there also remains a risk of flooding in places with wetter soils and higher rivers particularly in north-eastern Tasmania."
