DibbleLouisiana frost dates: first and last freeze
Louisiana spans USDA Zones 8 to 10, so frost arrives on different dates across the state. Most of Louisiana sits in Zone 9, where the last spring frost falls around March 1 and the first fall frost around December 1.
| Zone | Last spring frost | First fall frost | Frost-free days |
|---|---|---|---|
| Zone 8 | March 28 | November 7 | 224 |
| Zone 9 (most common) | March 1 | December 1 | 275 |
| Zone 10 | January 31 | December 15 | 318 |
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 Louisiana
- 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.
