Precipitation drought, often simply referred to as meteorological drought, is a condition characterized by a significant and prolonged deficit in precipitation compared to the average historical amounts for a specific region and time of year. This type of drought focuses directly on the lack of rainfall, snowfall, or other forms of precipitation. It is typically the first stage of drought to develop and is identified by measuring deviations in precipitation.

The duration and severity of precipitation deficits are key indicators. While a few dry days might not constitute a drought, a consistent pattern of below-average precipitation over weeks, months, or even years can lead to significant water shortages. These deficits can impact various sectors, including agriculture, water resources, and ecosystems. The geographical extent of the dry conditions is also a crucial factor in defining the scope of a precipitation drought.
