In Kerala, South India, the Vizhinjam coastal area has a natural harbour near to international trade routes. Sewage, solid wastes, industrial emissions, and fish wastes are the main sources of pollution in this coastal area. The main goal of this research is to determine the physico-chemical quality of beach sediments in the Vizhinjam beach area's coastal stretch. During the premonsoon season, surface sediment samples were collected from a beach area near the shore, and selected physico-chemical characteristics, including heavy metals, were determined using standard protocols. The alkaline character of beach sands is demonstrated by the average pH. The sediments on the shore are sandy loam in composition. The salt content of the food is higher than the potassium content. Sediments had high levels of calcium and magnesium. This will have a negative impact on soil water holding capacity and cause plant growth reduction in coastal locations. In comparison to other nutrients, the concentrations of nitrates, sulphates, and phosphate in beach sediments are low. Some of the heavy metals found in beach sediments (Zn, Fe, and Cu) are important micronutrients, whereas the presence of Pb, Cr, and Cd is hazardous to plants and fish. The heavy metal content in beach sediments was discovered to be in the following order: Fe > Cr > Pb > Zn > Cu > Cd.
