Geography Western Maranhão forms the boundary between the Amazon Rainforest and the vast savanna region, known as the Cerrado. Imperatriz is the place of intersection of many major roads and waterways. The landscape is characterized by gallery forests and stream valleys. Humid fields and palm paths are found where the water table is near the surface. Cerrado trees have twisted trunks covered by a thick bark, and leaves which are usually broad and rigid. Most trees are evergreen, but some lose their leaves during the dry season. The thick bark and roots are adaptations for the periodic fires which sweep the landscape. This adaptation protect the plants from destruction and make them capable of sprouting again after the fire. Climate Imperatriz has a typical tropical savanna climate, and is well known for its changeable weather conditions, with a wet season, during spring and summer months (November to April), and a dry one, during fall and winter months (May to November). In fact, July and August are the hottest and coolest months at once, when temperatures can range from to over within a single day, but the “feels like’ is always over . Occasional cold snaps can make temperatures drop to as low as , often made to feel cooler because of the windchill, but temperatures below are rare. This has a lot to do with why Imperatriz has a reputation for "four seasons in one day". It is not a city known for its stable weather patterns. The city has been described by locals as a city where you "wait five minutes and the weather will change". References Municipalities in Maranhão 1856 establishments in Brazil
