Explanation

The given climatic data points to a West European type (or Marine West Coast) climate based on the following characteristics:

  • Temperature: The temperature ranges from a mild winter minimum of 6.7°C to a cool summer maximum of 15.0°C. This narrow annual temperature range (8.3°C) indicates a strong maritime influence.
  • Rainfall: Precipitation occurs throughout the year with no distinct dry season. Even the driest months (May and June) receive a substantial 8.1 cm (81 mm) of rainfall. There is a slight maximum in winter (December receives 16.8 cm), which is characteristic of cyclonic rainfall in this climate region.

Other options are incorrect because:

  • Mediterranean type: Features a distinct, severe summer drought (usually less than 3 cm of rain in summer months) and warmer summers.
  • China type: Experiences much warmer summers (often above 20°C) with a pronounced summer maximum in rainfall.
  • St. Lawrence type: Has much colder, typically sub-freezing winters and a larger annual temperature range.
