Köppen-Geiger Global Climate Classification
The Köppen climate classification system divides terrestrial climates into five primary physiological zones based on vegetative thresholds, seasonal thermal variance, and precipitation periodicity.
All months average temperature above 18°C. Characterized by high annual precipitation, absence of winter season, and lush tropical rainforest biome.
Annual potential evapotranspiration significantly exceeds total precipitation. Diurnal temperature swings frequently exceed 25°C.
Mild winters with coldest month between -3°C and 18°C. Distinct 4-season cycle, typical of Mediterranean, Western Europe, and coastal North America.
Warm summer and severe freezing winters with continuous seasonal snowpack. Common across Canada, Northern US, and Scandinavia.
