Guayas' natural terrain is very diverse. The province has no elevations, except for the Coastal Range, which starts in Guayaquil and goes to Manabí. The areas west of the Coastal Range are desertic, with an average temperature of 23 °C. The areas east of the range belong to the Guayas Watershed. They are quite humid and fertile, especially in the north of the province, with an average temperature of 30 °C in the humid season (December–May) and 25 °C in the dry season (June–November).
