BUREAU of Meteorology data shows the Wimmera received 85.5 per cent less rain in January than usual.
The bureau's Wimmera district includes weather stations at Edenhope, Horsham, Kanagulk, Longerenong, Nhill, Stawell and Warracknabeal.
Duty meteorologist Dean Sgarbossa said the Wimmera received, on average, 14.5 per cent of the rain it usually did in January.
"There has been an inactive monsoon in the tropics and this has resulted in a lack of moisture being directed over Victoria," he said.
"That lack of moisture in turn has led to less rain."
Horsham Aerodrome weather station received an equal record low for January rain - 0.2 millimetres - last recorded in 2009.
Ararat Prison weather station received its record lowest January rain, 0.3 millimetres.
Nhill Aerodrome weather station received its second lowest January rain at 4.2 millimetres.
January's Wimmera temperatures were also cooler or warmer than the average.
Mr Sgarbossa said overnight minimum temperatures were cooler than those usually experienced in January.
He said the average departure from the normal expected temperature was about one degree Celsius lower.
"Daytime maximum temperatures at most centres in the Wimmera were also much warmer than those in the past," Mr Sgarbossa said.
"Temperatures were on average 1.7 degrees Celsius above the normal for January."
January's top Wimmera temperatures were high but generally not record-breaking for the month.
The region's maximum top temperatures were recorded on January 4.
Horsham was 44.2 degrees Celsius, Longerenong was 43.9 degrees Celsius and Nhill was 43.8 degrees Celsius.
Mr Sgarbossa said each of the above three temperatures were 14 degrees Celsius above the average maximum temperature for January.
