What is the typical weather in Monaco?
Monaco sits on the French Riviera and experiences a classic Mediterranean climate. Summers (June to September) are warm and mostly dry, with average highs around 26°C to 28°C. Winters (December to February) remain mild, typically ranging from 8°C to 14°C, though occasional cooler days occur. Rainfall is moderate, with the wettest months being October and November.
