Espoo has more than 90 ice rinks. Freezing one middle-sized ice rink requires about 120 cubic metres of water when freezing begins from zero. Under optimal conditions, freezing a rink takes almost a week. Conditions are ideal when the temperature is 5 to 10 degrees Celsius below zero. If the temperature is too low, more than 20 degrees Celsius below zero, the ice begins to crack. The ice rink stays in good condition as long as the temperature stays below freezing point. As soon as the temperature rises above zero degrees Celsius, the ice starts to soften. On the website ulkoliikunta.fi you can find information about the condition of ice rinks, when the ice rinks have been maintained, if there are changing rooms by the rink and also the opening hours of artificial rinks. Ice skating at your own risk.
