Forecasted temperature based media management
Aspects of the present disclosure configure a system component, such as a memory sub-system controller, to provide adaptive media management based on forecasted temperatures. The controller determines, at a current time, a first temperature of an environment associated with a host of a memory sub-system. The controller forecasts, at the current time, a second temperature that the host will be exposed to at a future time and computes, at the current time, a temperature range based on a difference between the first temperature and the second temperature. The controller selects, for an individual group of memory components, an individual media management operation from a plurality of media management operations based on the computed temperature range and performs the individual media management operation on the individual group of memory components.
