Antigua & Barbuda: Climate & Natural Resources

The twin-island nation of Antigua and Barbuda lies within the eastern Caribbean's trade-wind belt. This gives both islands a warm, relatively dry tropical climate compared with many of their more mountainous neighbors. Rainfall is modest and unevenly distributed across the year, a pattern that has long shaped the islands' agriculture and water supply. Hurricane season, running from June through November, brings the greatest weather risk, and the country has weathered several destructive storms in recent decades, including the devastation of Barbuda by Hurricane Irma in 2017.

Mineral wealth on the islands is limited to modest deposits of limestone, clay, and sand, reflecting a geology of low coral limestone rather than volcanic rock. Far more significant to the national economy are the surrounding marine and coastal ecosystems: coral reefs, seagrass beds, and mangrove stands that support fisheries, protect the coastline from storm surge, and sustain the beaches central to the tourism sector. Agricultural output, mainly small-scale production of vegetables, pineapples, and livestock, plays a secondary economic role.

Because the islands possess few extractable resources, the country's prosperity depends heavily on the health of these natural systems, particularly the coastal environment that draws visitors and the fisheries that support local livelihoods, making environmental stewardship an economic as well as ecological priority.
