: the essentially uniform local climate of a usually small site or habitat

Did you know?

The microclimate of an industrial park may be quite different from that of a nearby wooded park, since the plants absorb light and heat while asphalt parking lots and rooftops radiate them back into the air. A microclimate can offer a small growing area for crops that wouldn't do well in the wider region, so skilled gardeners take advantage of microclimates by carefully choosing and positioning their plants. San Francisco's hills, oceanfront, and bay shore, along with its alternating areas of concrete and greenery, make it a city of microclimates.
