Thousands of Canberrans are expected to pack the city's official New Year's Eve event in Civic on Monday, which will include firework displays from City Hill at 9pm and midnight, as well as live music in Civic Square from 6pm.

Canberra acoustic soul band Tuchasoul is leading the local talent on show at the all ages, alcohol-free event, which will headlined by producer PACES.

The festivities could be dampened by some rain, with the Bureau of Meteorology forecasting a possible thunderstorm on Monday.

The bureau said there was a 50 per cent chance of showers and an isolated thunderstorm in the afternoon and early evening, although only one millimetre is expected to fall.

Canberrans will otherwise be treated to a partly cloudy top of 30 degrees on the last day of 2018, as the ACT's summer heatwave rolls into a second week.

Revellers will be able to catch buses every 20 minutes between major town centres until 2am on Monday night, with Transport Canberra offering partygoers a $10 discount on Uber fares from bus stops to their homes.

Transport Canberra will run late night services between Gungahlin and Kingston and between Belconnen and Tuggeranong via the city and Woden.

Northbound bus services depart platform 5 in the City Bus Station, while southbound services depart platform 7.

ACT Policing's New Year's Eve operations commander, Mick Calatzis, said Canberrans should expect a heavy police presence around Civic.

Mr Calatzis said officers would be targeting alcohol and drug-related violence, as well as drink driving.

"Our outcome is that we want everyone to have a very safe and happy event," Mr Calatzis said. "But like all good planning, we expect the best but also plan for the worst."

Tourist Lou Loui, who spent Sunday afternoon at Commwealth Park, was excited to celebrate New Year's Eve with friends she had made during her travels in Australia.

A number of road closures will be in place throughout the city during the New Year's Eve festivities.

London Circuit, between Northbourne Avenue and Akuna Street, will be shut from 5pm on Monday to 2am on Tuesday, January 1.

Northbourne Avenue's southbound lane, between Cooyong Street and Vernon Circle, will be shut from 8.40pm to 9.30pm and from 11.40pm to 12.30am on Tuesday, January 1.

Vernon Circle between Commonwealth Avenue and Northbourne Avenue will also be closed to traffic during that time.

The RSPCA is advising owners to take extra care of their pets to help them cope with the fireworks displays, which are known to scare and confuse animals.

The animal welfare agency recommended owners exercise their pets during the days to help them settle at night, play music to distract them from the fireworks and avoid tying them up.
