While it may still be winter, Canberrans could be forgiven for thinking spring had arrived early to the capital.
Clear blue skies, barely any wind and temperatures nudging into the high teens saw people flock outdoors on the last weekend of winter, soaking up every bit of sun they could.
The warm weather is set to hang around for a few days more, thanks to a high pressure system hovering over the ACT and NSW.
However, the Bureau of Meteorology has warned it's not time to pack away the winter woolies for another year just yet.
Forecaster at the bureau Alex Majchrowski said some chilly temperatures are on their way later in the week.
"There will be a few warm days, but the maximum temperatures will drop down over the next few days due to a cold front and there being not much precipitation," Mr Majchrowski said.
"There will be the occasional cold front in the weeks to come."
Temperatures are expected to reach a high of 18 degrees on Sunday with some light winds later in the day.
However, the maximum temperatures will drop back down to 14 degrees on Tuesday with the minimum set to almost hit sub-zero with a low of 1 forecast.
Up to 10 millimetres is predicted to fall in the capital in the latter parts of the week with showers expected on Thursday, Friday and Saturday.
Mr Majchrowski said more high pressure systems were expected in the weeks to come as spring arrived.
"When spring does come, it is not a clean break, and we do get a few cold fronts making their way to NSW and the temperatures drop occasionally," he said.
"Some cold fronts slip in through the south, and that will also likely to be the case in coming weeks."
It comes as the bureau earlier this week said the ACT had an 80 per cent chance of experiencing a wetter than average spring this year.
Canberra's mean rainfall for the month of September is 65 millimetres.
"That is generally the wettest month for the ACT," Mr Majchrowski said.
The average maximum temperature for the month of September is 16 degrees, which then rises to an average of 20 degrees during October.
The bureau said Monday was expected to reach a top of 15 degrees after an overnight low of 14 with partly cloudy conditions.
