January was wetter than average for Victoria, mostly due to record daily rainfall at the end of the month.
State-wide, January rainfall was 68 per cent above the long-term average of 39.5 millimetres and the highest since 2011.
Rainfall totals for the month were above average across most of Victoria, tending to near-average in parts of Central Gippsland, the north and the Mallee.
Parts of western Victoria and scattered areas in the east received more than double their average January rainfall.
The highest daily totals were recorded in the state's north east, where severe thunderstorms produced heavy falls.
Another cold front, and a low pressure trough - which brought tropical moisture - crossed Victoria on January 29.
Daily rainfall totals exceeded 50mm at many sites in central and north east Victoria.
Many sites had their highest January daily rainfall on record in the 24 hours to 9am on January 30, including Lake Eildon and Highlands, which both have more than 100 years of observations.
Several sites had their highest total January rainfall on record, including Cape Otway Lighthouse - where observations started in 1861 - and others had their highest total January rainfall in two decades.
After a mild first few days, a cold front brought cool temperatures to most of the state on January 4 and 5. This was followed by a period of warm temperatures, and from January 9 a heatwave started to develop across Victoria.
Daytime temperatures peaked on January 10-11 and were 8-10°C above average across the state.
A cold front on January 15 delivered mild daytime temperatures to Victoria, and even a few centimetres of snow at Mount Buller.
Maximum temperatures gradually increased from January 21, culminating in a heatwave on the 24th and 25th - when many sites across the state recorded daytime temperatures in the high-30°Cs to low-40°Cs.
The highest daytime temperature recorded in Victoria this January was 43.9°C at Ouyen Post Office and Walpeup Research on January 24.
The state's warmest night was recorded during the same event, when Walpeup Research's minimum temperature only dipped to 28.3°C on January 25.
Despite some hot days, the state-wide mean maximum temperature was only 0.28°C above the long-term average - the coolest January since 2015.
Night-time temperatures were above average in parts of southern and eastern Victoria.
