On this page of the Mafia Definitive Edition guide, you will find the answers to two questions – how to change the current time of day (e.g. to the night) and how to change the weather conditions to rain.
Time of day and weather conditions in main missions
The time of day and weather are both fixed in the main missions and this is often justified in the plot. For example, in the Visiting Rich People main mission, the protagonist's goal is to sneak into an empty mansion after dark. The game does not let you change the time of day or weather conditions during the main storyline.
Changing the time of day
Changing the current time of day is possible only in the Free Ride mode, available from the game's main menu. There, you can freely explore the world map without doing the missions
To change the time of day, you must visit the conference room on the ground floor of Salieri's bar.
There are 4 paintings hanging on the wall and each of them allows you to change the time of day - morning, afternoon, evening, or night.
After interacting with a painting, the game will display a city preview confirming the change.
Changing the current weather conditions is also possible only in Free Ride mode. In this case, you must visit Salieri's office on the upper floor of the bar – the accompanying picture shows it.
There are 2 paintings hanging in the office - you can choose between rainfall and nice weather. When it rains, vehicles are harder to drive and prone to slide, especially if you chose the simulation driving model.
The game displays a short preview confirming the change of weather conditions.
