- Presently frost days vary between 160 days per year on the Allegheny Plateau, to 70 days in Baltimore, and 80 days in the southern Chesapeake Bay region (source: MD State Climatologist). Thus, the 100 day value at present represents an average of these regional estimates. To determine model predicted Frost Days in a specific location, subtract 100 days from the model projection, and add in the 1979-2000 average number of frost days at your location.
