Welcome to the Maryland Regional Climate Monitoring portal.
The Maryland State Climatologist Office provides comprehensive, near real-time daily and monthly analyses to track the state's climate health. This portal serves as a central hub for analyzing both near real-time daily weather fluctuations and long-term historical extremes via area-averaged temperatures, heat stress accumulations, and precipitation. These tools provide the historical context necessary to understand current atmospheric and environmental conditions across the diverse regions of Maryland.
View the last 30 days of temperature and precipitation compared against the current 1991-2020 daily normals and standard deviations.
Track cumulative thermal heat models for agricultural phenology milestones, crop heat stress limits, and residential utility infrastructure load demand.
Track the structural frequency of monthly extreme weather events, monthly threshold exceedances, and long-term growth windows across Maryland.
