Weather in Russia
Next to consider when planning your travel to Russia is temperature. Russia is most beautiful in winter. After all, it is a northern country (coldest in the world actually) that spends 8/12 months in winter and knows how to make the most of it. If you travel to Russia in winter, you can save lots of money & expect a better service, & get to do many fun things, such as troika rides. If you don't like the cold, your safer bet is to travel to Russia next summer.
Don't try to fool the weather and travel to Russia in inter-seasons. You might be in for a big surprise. Of course, you will travel to Russia for different reasons than Napoleon, but you should know that snowing starts in October and ends in April! Or you could just ask your travel agent who is helping you to organize your travel to Russia to ensure that you spend as little time as possible in the snow.
