Climate Zones of Spain: A Geographical Analysis

Climate Classifications in Spain

The types of climate in Spain are traditionally classified into four major categories: oceanic, Mediterranean (with variations), subtropical, and mountain. Each influences a clearly defined geographic area.

1. Oceanic Climate

Also called the Atlantic climate, this atmosphere extends throughout the north and northwest of the peninsula, from the Pyrenees to Galicia. It is characterized by abundant rainfall, which rarely exceeds 1000 mm, distributed regularly throughout the year. Consequently, the landscape is very green. Temperatures are generally mild due to the proximity of the sea; winter ranges from 12°C to 15°C, and summer temperatures are around 20-25°C.

2. Mediterranean Climate

This climate is dominant in Spain, extending along the Mediterranean coast, the interior of the peninsula, and the Balearic archipelago. Due to regional differences, it is divided into three branches:

• Typical Mediterranean: Covers much of the coast, some interior areas, Ceuta, Melilla, and the Balearic Islands. Rains are irregular (400 mm to 700 mm annually), concentrated in autumn and spring. Winters are short and mild, while summers are long and hot. The average annual temperature is between 15°C and 18°C.
• Continental Mediterranean: Located in the Plateau and the depressions of the Ebro and Guadalquivir. It features extreme temperatures between -13°C and 25°C. Winters are long and very cold, while summers are very hot. Rainfall is low (around 400 mm), often appearing as storms in July and August.
• Dry Mediterranean: Occurs mainly in the southeast, specifically in Murcia, Alicante, and Almeria. Rain is extremely rare (less than 300 mm per year), leading to frequent droughts. Temperatures are similar to the typical Mediterranean, though summer heat is often more intense.

3. Subtropical Climate

This climate appears only in the Canary Islands due to their proximity to the Tropic of Cancer and the arid coast of Africa. It is characterized by trade winds and cold water currents. Temperatures remain high throughout the year, averaging between 18°C and 21°C. Rainfall is low (less than 250 mm) and concentrated in winter. Because of this, there are no permanent rivers, and rain often forms torrents.

4. High Mountain Climate

This climate appears in large mountain ranges such as the Pyrenees, the Central System, the Iberian System, the Cantabrian Mountains, and the Penibética range. Winters are very cold, and summers are cool. Rainfall is abundant, increasing with altitude, and generally falls as snow. Slopes facing north are typically colder.
