Simple Summary: The study delves into how environmental conditions impact metal concentrations in Sparisoma cretense tissues, crucial for advising the species' health and broader implications for food security. Spanning 2022–2023, it notes variations in Al, Zn, Cd, Pb, Fe, and Cu levels across islands, with significant increases during warm seasons in 2023. The fluctuations arise from multiple factors: rising temperatures, marine activity, weather shifts, water quality, and human influences. Geological composition, marine currents, and sediment patterns also contribute. Understanding these complexities through ongoing research and surveillance is vital for conserving and managing marine ecosystems in the Canary archipelago. This study investigates the impact of varying environmental conditions on the metal composition within the tissues of Sparisoma cretense, contributing to the understanding necessary to offer scientifically sound advice regarding the health status of this species. This knowledge extends beyond fishery production, encompassing implications for food security. The data span the years 2022 and 2023, encompassing both cold and warm climatic seasons. The concentrations of various metals, such as Al, Zn, Cd, Pb, Fe, and Cu, exhibited noteworthy variations across the islands, with significant increases recorded in 2023, particularly during the warm season. The intricate interplay between multiple factors shaped the availability of the analyzed elements in S. cretense. Factors such as rising temperatures during the warm season increased biological activity in marine ecosystems, seasonal fluctuations in weather conditions, water quality, and anthropogenic influences, all contributing to the observed variations in metal concentrations. Additionally, the geological composition of each island and the patterns of marine currents and sediment transport play pivotal roles in these differences. Comprehensive scientific research, monitoring, and environmental surveillance are essential for a holistic understanding of this variability and providing valuable insights for the conservation and management of marine ecosystems in the Canary archipelago.
