metropolitan France: generally cool winters and mild summers, but mild winters and hot summers along the Mediterranean; occasional strong, cold, dry, north-to-northwesterly wind known as the mistral;

French Guiana: tropical; hot, humid; little seasonal temperature variation;

Guadeloupe and Martinique: subtropical tempered by trade winds; moderately high humidity; rainy season (June to October); vulnerable to devastating cyclones (hurricanes) every eight years on average;

Mayotte: tropical; marine; hot, humid, rainy season during northeastern monsoon (November to May); dry season is cooler (May to November);

Reunion: tropical, but temperature moderates with elevation; cool and dry (May to November), hot and rainy (November to April)

metropolitan France: mostly flat plains or gently rolling hills in north and west; remainder is mountainous, especially Pyrenees in south, Alps in east;

French Guiana: low-lying coastal plains rising to hills and small mountains;

Guadeloupe: Basse-Terre is volcanic in origin with interior mountains; Grande-Terre is low limestone formation; most of the seven other islands are volcanic in origin;

Martinique: mountainous with indented coastline; dormant volcano;

Mayotte: generally undulating, with deep ravines and ancient volcanic peaks;

Reunion: mostly rugged and mountainous; fertile lowlands along coast

metropolitan France: flooding; avalanches; midwinter windstorms; drought; forest fires in south near the Mediterranean;

overseas departments: hurricanes (cyclones); flooding;

volcanism: Montagne Pelee (1,394 m) on the island of Martinique in the Caribbean is the most active volcano of the Lesser Antilles arc, it last erupted in 1932; a catastrophic eruption in May 1902 destroyed the city of St. Pierre, killing an estimated 30,000 people; La Soufriere (1,467 m) on the island of Guadeloupe in the Caribbean last erupted from July 1976 to March 1977; these volcanoes are part of the volcanic island arc of the Lesser Antilles that extends from Saba in the north to Grenada in the south

regional risks include landslides, mudflows, avalanches, earthquakes, volcanic eruptions, flooding; land subsidence in Venice

volcanism: significant volcanic activity; Etna (3,330 m), which is in eruption as of 2010, is Europe's most active volcano; flank eruptions pose a threat to nearby Sicilian villages; Etna, along with the famous Vesuvius, which remains a threat to the millions of nearby residents in the Bay of Naples area, have both been deemed Decade Volcanoes by the International Association of Volcanology and Chemistry of the Earth's Interior, worthy of study due to their explosive history and close proximity to human populations; Stromboli, on its namesake island, has also been continuously active with moderate volcanic activity; other historically active volcanoes include Campi Flegrei, Ischia, Larderello, Pantelleria, Vulcano, and Vulsini
