Summer in Almaty is really hot, it's better to take siesta or stay inside between 11.00 and 17.00. Average temperature of July is the same as on the islands of Sri Lanka or Kalimantan. Average temperature in January can be compared with north of Finland.
I like Almaty summer for two things ( so far):
1.For it's warm breezy summer nights with it's special smell. You can go out in t-shirt at night and don't bother to take a jacket with you.
2. For it's fountains. Perfect for dry and hot summers. There are 125 (!) fountains in the city (wikipedia knows everything). Again, I like fountains at night, especially those with floating lights. Here you see pictures of different quality but all of them are original without any Photo shop tricks.
