Petrified Forest National Park is a semi-arid grassland. Temperatures range from above 100° F (38° C) to well below freezing. About 10 inches (25.4 cm) of moisture comes during infrequent snow in the winter and often violent summer thunder-storms. Animals and plants are adapted to extremes in temperature and moisture. You should be ready too. Check out the forecast before you arrive and plan accordingly.
