The landscape of Tabonuco reflects the typical terrain of inland Sabana Grande, where rural and semi-rural character predominates. This barrio's interior location means it experiences the subtropical climate common throughout the region, with typical rainfall patterns for southern Puerto Rico. The area is generally removed from direct coastal influence, allowing for a mix of agricultural land, dispersed residential properties, and open terrain that distinguishes inland barrios from their seaside counterparts.

Property in Tabonuco tends toward larger parcels and agricultural land use rather than dense urban development. Owners in this barrio typically hold land for farming, ranching, or single-family residential use with substantial acreage.
