I will be travelling there from 1st August till 11 August. As I'm from Singapore which is summer all year round and wind is rather hot and dull...I understand that it would be summer as well in Russia at that point of time but how would the night be and would the wind be chilly? What sorts of clothes and shoes should I bring along?
It will likely be quite warm. The past two summers we had heatwaves in August in Moscow (28-37 degrees C.). Most places are air-conditioned. The atmosphere in Moscow is generally very dry but humidity rises when there are summer thundershowers.
But it's always best to bring layers of short- and long-sleeved shirts. Shorts are not commonly worn in the city but OK if you are out in the countryside. Sandals and walking shoes are fine unless you'll be dressing up for business or a formal night out. almost 6 years ago
