Only 23.6mm of rain was recorded at the Bureau of Meteorology (BoM) weather station at the Tamworth airport during the month of January.

That's only a quarter of the amount of rain that soaked the region in January 2020, and almost a tenth of the rain that was dumped on Tamworth last month.

December downpours delivered Tamworth the wettest end to a year in decades, but the weather soon dried out.

January has seen a reprieve from the rain, and it's extended to the Chaffey Dam catchment.

The head of the Peel River near Nundle, which runs into Tamworth's main water supply, copped 39.6mm of rain for the month, compared to 137.6mm for the same time last year.

The dry weather and clear skies didn't bring the heat to Tamworth though, and the La Nina system is still active across Australia.

Tamworth's top temperature so far in 2021 was much lower than the hot January days of the past five years. The mercury peaked at 36 degrees on January 27, a much milder maximum than last year when the temperature soared to more than 42 degrees on January 5.

Chaffey Dam has waded through this month without much change, with the supply starting the year at 41.1 per cent full, and ending the month at about 41.8 per cent.

Residents tapped into Tamworth's town water supply are still being supplied by sources outside Chaffey Dam - like the Peel River pump station and Dungowan Dam - as council works to keep the plug in Chaffey.

Lake Keepit kicked off 2021 at 36.6 per cent capacity, and had risen to more than 44 per cent by the end of the month.

The rest of this week in Tamworth is set to be partly cloudy and bring possible rain and storms, according to the BoM.
