The islands are part of a volcanic arch. According to COUNTRYAAH, the highest mountain is Soufrière in the northern part of Saint Vincent, which is an active volcano and reaches up to 1,234 m. The last eruption occurred in 1979 and caused great damage. The rivers from this and the other mountains are made up of short, short streams that cut through the dense forest. The coasts have coral reefs and dazzling white sand beaches.
According to BRIDGAT, the islands have a warm and humid tropical climate. The average annual temperature in Kingstown is 27 °C. The mountain areas receive up to 4,000 mm of rain per year; the corresponding figures for the coastal areas are 1,500 and 2,000 mm. Characteristic plants in the lush vegetation are hibiscus and various palm trees.
In 2009, there were six protected areas in Saint Vincent and the Grenadines. The St. Vincent Parrot Reserve (44 km2) was set aside to protect the endemic parrot species Saint Vincent amazon (Amazoʹna guildiʹngii) which is the country’s national symbol.
