Islam in cold countries?

Having class canceled yesterday really made my day! I was able to get some homework and studying done in the morning but going outside for the first time yesterday morning, the cold really hit me. I was definitely not expecting it to get so cold so fast. All this got me thinking, sometimes Christian church services are affected by the cold, does an Islamic service ever get affected by the cold too? Is there a correlation between the Muslim population in colder or warmer countries? I was able to find an interactive map that shows the Muslim population in different countries. This shows that there is a higher Muslim population in Northern Africa and Middle Eastern countries than most of the other countries. These countries are all normally warmer countries that do not experience the same level of winter as we do. The most likely would not get snow or have below freezing temperatures. I was also able to find some information about how widespread Islam is all throughout the world. I could not find anything concrete about if an Islamic service would get canceled, but I would assume that they would if there was severe weather or other circumstances that may impact the safety of those who attend.
