Features
Climate savannas and woodlands differs clearly distinguished seasons.These are called summer and winter.However, they do not differ in amplitude imposing temperatures.As a rule, it is warm all year round, weather is never frost.The temperature of the whole year ranges from eighteen to thirty-two degrees.The rise is usually gradual, with no sudden jumps and falls.
