Parts of the Top End of the Northern Territory have gained more than their monthly average rainfall in the past week, making up for some of the wet season deficit.

Widespread 100-to-300mm has fallen over the Darwin-Daly, Arnhem, Roper McArthur and Victoria River districts with as much as 600mm on the north coast of the Arnhem.

According to WeatherZone, Millingimbi on the north coast gained 590mm in the past week, almost double its monthly March average for the past decade.

Darwin picked up about 200mm in the week, its wettest week since this time last year. It takes its March total to 373mm, 52mm higher than its monthly average.

Nearby Maningrida amassed 500mm in the week, including 336mm in the past two days, its wettest two-day spell in more than a decade.

Recent rain has also been significantly high inland, including the Katherine area, where more than 300mm has fallen.

The Katherine Rural College has had its wettest week in two years, gaining about 350mm since last Sunday morning.

Brett Dutschke from WeatherZone said almost all of the Top End was still drier-than average for the wet season so far.

Darwin has had 1290mm since October, almost 300mm short of the October-to-March average.

The Barkly Tableland where dry conditions have forced some destocking of cattle in recent months has not shared in the bigger falls.
