Guasimas is a barrio located in Arroyo, a municipality on the southern coast of Puerto Rico in the southeastern region. The barrio covers approximately 2.46 square kilometers and represents part of Arroyo's inland geography, positioned away from the immediate coastal areas that define much of the municipality's character. Arroyo itself sits along the Caribbean Sea, and Guasimas occupies terrain typical of the southern coastal plain, characterized by drier conditions and lower elevation compared to the island's central mountainous interior.

The landscape of Guasimas reflects the rural and semi-rural character common to inland barrios in this part of Arroyo. Rather than dense urban development, the barrio features more dispersed settlement patterns, with properties ranging from smaller residential parcels to larger agricultural or mixed-use holdings. The southern coastal region of Puerto Rico tends toward lower rainfall and vegetation adapted to semi-arid conditions, which historically supported both subsistence farming and grazing lands. Property in Guasimas would typically consist of varied parcel sizes, reflecting the gradual settlement patterns of rural municipalities where land ownership often combines residential use with agricultural potential or simply undeveloped acreage.
