Representative figures from each country's largest city. High / low are average daily temperatures (°C); “Feels” allows for humidity.
The Baltics (Estonia, Latvia & Lithuania)
By late autumn the first frosts return and days shorten noticeably; Tallinn often has chilly, gray weather with winds off the Gulf, while inland areas see more persistent frosts at night. Museums and cafés feel cozier and hotel rates drop outside school holidays, but outdoor sightseeing can be damp and blustery. Waterproof footwear and a warm midlayer will keep you comfortable for shorter daylight excursions.
Poland & the Northern Plain (Poland & Belarus)
By late autumn persistent winds and rain can dominate, turning the plains gray and chilly; November often sees the first snowfalls at month’s end. City sightseeing is quieter and hotel prices fall outside holiday windows, but daylight is short and conditions can feel damp. Waterproof boots, a warm coat and an umbrella are practical for walking tours and museum hopping.
The Carpathians & Transylvania (southern Poland, Slovakia, western Ukraine & Romania)
Late autumn brings the first permanent snowfalls on higher ridges and a rapid drop in temperatures; lower valleys see misty mornings and damp days that can make trails slippery. Many mountain huts reduce services after mid-October, so plan logistics carefully if traveling off-peak. Insulated footwear and waterproofs are essential if you intend to remain active outdoors.
Ukraine & Moldova Lowlands (central & eastern Ukraine, Moldova)
Late autumn cools quickly, with more frequent rain and the first frosts appearing by November across the plains; overcast days become common and daylight shortens. Rural roads can become muddy while cities shift indoor with café life and museum visits. A warm coat, waterproof footwear and an umbrella are practical for sightseeing and travel between towns.
Black Sea Coast & the Danube Plain (Romania, Bulgaria & southern Ukraine)
Late autumn cools noticeably with more frequent rain and the first frosts inland by November; seaside towns become quieter and off-season prices fall. Bird migration creates activity in the Danube Delta while cultural attractions in Constanța and Varna remain open. Pack waterproof layers and warm clothing for blustery coastal walks and birding trips.
European Russia West of the Urals (St. Petersburg, Moscow & surrounding regions)
Late autumn brings shorter days and increased rainfall, with the first snowfalls often arriving by November and changing city streets to slush and ice. Heating is on in public spaces and transport runs to winter timetables; plan for earlier museum and theatre nights as outdoor time becomes briefer. Insulated footwear and waterproof outer layers are necessary for exploring iconic boulevards.
