What does microclimate mean?
A microclimate is a small area whose atmospheric conditions differ from those of the surrounding region. Unlike a brief weather episode, a microclimate describes a recurring or persistent local pattern, such as the cooler, wetter conditions beneath a woodland, the warmth of a sheltered courtyard, or the breeze corridor between tall buildings. Its differences may involve temperature, humidity, wind, precipitation, sunlight, or soil conditions, and they can result from topography, vegetation, water, geology, or construction. The term is used in environmental science, geography, agriculture, horticulture, architecture, and urban planning, and figuratively for the distinctive social or cultural atmosphere of a place. A microclimate is not necessarily extreme: it simply represents a locally distinctive set of conditions within a larger climatic area. The word is useful because it encourages attention to scale, showing how a landscape or built environment can preserve, redirect, or create environmental patterns that broad regional averages conceal.

Where does microclimate come from?
The English word is a compound formed in the 20th century from the prefix micro-, meaning small, and climate. The prefix derives from Greek mikros, meaning small, while climate comes through Latin from Greek klima, meaning slope or region, and is related to klinos, meaning slope. The combination originally referred to the study and description of small-scale climatic conditions and later became established as a noun for the localized climate itself.
