People attending Anzac Day services in Melbourne are advised to take umbrellas and waterproof coats, with the weather bureau forecasting a strong chance of morning rain on Tuesday.

Police and security guards have vowed to be on alert following an apparent terrorist attack in Paris last week in which a gunman killed a policeman and wounded two others on the Champs-Elysees.

The gunman was shot dead and Islamic State claimed responsibility for the attack.

More than 60,000 people are expected to attend the dawn service at the Shrine of Remembrance. The service starts at 6am but people are asked to assemble on the Shrine Forecourt starting at 4.30am.

Metro Trains will put on pre-dawn services into the city across its networks - the earliest at 3.51am from Belgrave and the 3.55am from Lilydale. Extra trams will run across the network, from as early as 3.58am for the Route 109 service from Box Hill Central.

Trams will run every five minutes from 3.58am to 5.08am.

The Melbourne Anzac Day parade will start at 9am at the corner of Swanston and Flinders streets, moving down St Kilda Road to the Shrine.

The Bureau of Meteorology has forecast that Melbourne will be cloudy, with a high chance of rain around dawn, easing to passing showers, with up to 8mm falling over the day.

The temperature forecast is relatively mild, with an overnight minimum of 15 degrees, and a light wind, rising just a few degrees to 19.

Victoria will experience a cool to mild but wet day, particularly early. Horsham is expected to have rain at times and a top of 19 degrees, Ballarat 16 degrees, Mansfield 18 degrees, and Bairnsdale 21 degrees.

Victoria's second-largest Anzac Day dawn service is expected to be at Point Danger, near Torquay, with more than 10,000 people tipped to attend.

Geelong will hold its first dawn service on Tuesday at 6am at Eastern Beach, followed by a march through the city at 11am.

Ballarat has a day-long program of events starting with a 5.45am dawn service at the Cenotaph in Sturt Street, and a 10.30am march from the RSL in Lydiard Street North to the Cenotaph followed by a second service.

Victoria Police acting Commander Peter O'Neill said on Friday there were no specific threats, and there were was no change in security plans for Anzac Day following the Paris attack.

He said there would be a slightly larger police presence on Tuesday, barriers in place to allow police to control traffic flow and to prevent the risk of cars being used in an attack.

Security measures will be tight for the AFL Anzac Day match between Collingwood and Essendon on Tuesday night, which 75,000 people are expected to attend.

Commander O'Neill urged the public not to be intimidated, and to "come out and enjoy the day, embrace it".

"We're looking forward to the day, and we just want to assure the community is safe."
