Question

What is the highest temperature that it can get in grasslands?

Answer 1

The climate for grasslands is basically dry. Precipitation usually does not exceed 100 cm per year, with a minimum near 20 cm per year.  Also, grasslands tend to be in temperate  to subtropical areas, often with cold winters and hot summers. Average annual temperatures range from below 0 degrees C to about 20° C.  The warmer end of this range would probably tend towards tropical savanna.  As moisture levels increase, grasslands usually give way to temperate forests or taiga, depending on the temperature.

One problem with determining the exact climate for this biome is historical.  There is now some evidence  that suggests that some prairie (at least that intermixed with forests in the more humid eastern United States) was artificially maintained by native American tribes using fire as a tool.  By eliminating trees and creating grasslands they increased biological diversity and populations of such game species as bison and deer.  So, to what extent are grassland habitats the results of "natural" processes or of human interference?
