Frederick climate
Summer heat, urban heat islands, rain, flood questions, winter cold, cooling, and indoor choices shape the year
The City of Frederick issues heat alerts when forecast temperature or heat index is expected to reach 95 degrees Fahrenheit or higher and estimates that urban heat islands can raise temperatures by 3 to 5 degrees. The city also states that 11 percent of Frederick is in or near a 100-year floodplain. Keep the official NOAA 1991 to 2020 normal period separate from current alerts and the exact property.
Inspect air conditioning, insulation, windows, shade, roof, gutters, drainage, basement, trees, power, water, internet, insurance, and the route to care. Keep parks, recreation, library, meal, and home activities available when heat or rain shortens outdoor plans.
