The state is also located inland, which means that it is not affected by the moderating effects of the ocean. This results in extreme temperatures in Haryana, with highs of over 40 degrees Celsius (104 degrees Fahrenheit) in the summer and lows of below 0 degrees Celsius (32 degrees Fahrenheit) in the winter.
