DibbleMaryland frost dates: first and last freeze
Maryland spans USDA Zones 5 to 8, so frost arrives on different dates across the state. Most of Maryland sits in Zone 7, where the last spring frost falls around April 10 and the first fall frost around October 29.
| Zone | Last spring frost | First fall frost | Frost-free days |
|---|---|---|---|
| Zone 5 | April 30 | October 1 | 154 |
| Zone 6 | April 21 | October 17 | 179 |
| Zone 7 (most common) | April 10 | October 29 | 202 |
| Zone 8 | March 28 | November 7 | 224 |
These are typical dates for the zone, not a forecast. A frost can land a couple of weeks either side, and your own yard has its own microclimate. Dibble pins the dates to your ZIP code and warns you the night a frost is actually coming.
What to do with these dates in Maryland
- Count back from the last spring frost to know when to start seeds indoors.
- Wait until after it to move out tomatoes, peppers, and anything else frost-tender.
- Count back from the first fall frost to find the last useful sowing date.
- Cover or harvest before the first fall frost lands.
