Brittany
The old walled city of Saint-Malo, Brittany région, France.
The oceanic climate in Brittany significantly shapes the region's weather through several distinct characteristics:
- Temperature Stability: The region experiences low annual temperature variation. For example, in Brest, average temperatures remain relatively mild, typically around 43 °F (6 °C) in January and 61 °F (16 °C) in July.1
- Precipitation and Humidity: The climate is marked by extreme humidity and moderate annual rainfall, totaling approximately 35 inches (890 mm), which is often accompanied by persistent cloudiness and haze.1
- Wind Patterns: Brittany is subject to frequent and sometimes violent west winds that blow almost constantly across the peninsula.1
- Variability: A defining feature of this oceanic influence is the high degree of weather instability; conditions can change rapidly, often shifting several times within a single day.1
This climate is a result of the region's position protruding into the Atlantic Ocean, where prevailing westerly winds bring moisture and relatively warm air deep into the continent.23
