Temperatures Aren't Always Freezing
People have this misconception that Russian weather is always like Siberia in the winter, and that Russians spend their days bundled from head to toe in furs, but this is just not true. Summer in Russia is usually lovely, and St. Petersburg is known for its hot weather. Before your journey, look up the local weather forecast and pack accordingly.
Remember to dress appropriately if you are going during the summer. Women should cover their heads and wear long skirts or dresses in various Orthodox churches, while men should not wear hats. Sandals are also out of style in Russia, so opt for a pair of light, closed-toe shoes instead.
