Microclimate

A set of localised atmospheric conditions, especially relating to temperature, sun hours and/or rainfall-relative humidity, for a small location, which differ from the general geographical surrounding area. This could range, for example, from a small part of a bowling green which differs from the main body of a green, to an expanse of ground, field, or the like, which has a distinctly different climate from surrounding areas due to it being sheltered and acting as a relatively dry sun trap and as a frost free pocket over the winter.
