What is the Ideal temp and humidity for a russian tortoise?

I keep the humidity at about 40% and the heating at about 27 celcuis in winter, in summer it's hotter because they are outside and temps reach 35 celcius..

But they are quite sturdy little fellas they don't mind a drop in temps as long as it's not brisk or to low
