Typically, frost can occur when the temperature falls below 36°F, especially in rural areas. It is a localized phenomenon and can be quite variable across a small area. Debra LaGattuta is a Master Gardener with 30+ years of experience in perennial and flowering plants, container gardening, and raised bed vegetable gardening. She is a lead gardener in a Plant-A-Row, which is a program that offers thousands of pounds of organically-grown vegetables to local food banks.

Average Frost Dates For Major Cities

Frost becomes more widespread when the temperature falls below 32°F with some freeze possible. A Freeze Watch may be issued a few days ahead of time if the potential exists for temperatures to fall into these thresholds. A Frost Advisory is issued when temperatures are forecast to be in the 33°F to 36°F range with good radiation conditions.

You can learn more about this age-old technique below. The area has seen about 791.3 inches of snow since 1878, according to data from the National Weather Service, for an average of about 4.3 inches of snow between Oct. and May. Most vegetables and herbs need to be harvested before the first frost, which will turn them brown or mushy. A 29 to 32 degree frost may only damage the leaves, inhibiting their ability to photosynthesize. The second frost might not come for another few weeks allowing a little more harvest time. Below are images depicting the earliest, median, and the latest dates for the last 36°F Frost, 32°F, and 28°F freezes across our region.

However, note that some cool-seasons crops such as kale and lettuce do not grow well in hot temperatures, which can cause bolting issues. For some gardeners, especially in the South, a break to avoid summer heat is needed, but they can start once the heat has passed. The chart below includes average frost dates for cities across the U.S.

In addition to our map and suggested websites, your local gardening center and your personal experience can be your most reliable source. It's a good idea to jot down the actual last and frost dates in your area to keep an accurate record year by year. Average frost dates by zone include data for a wide range of climates and locations. You'll also want to keep an eye on the season's weather trends for your area.

How Accurate Are the Planting Dates?

The changing color of leaves during fall is a completely separate phenomenon from the falling temperatures. Leaf color change is caused by the shortening of days from summer to fall. Interestingly, the brilliant fall color is there all summer, but until fall, it is hidden by the production of (green) chlorophyll. As days shorten in fall, leaves shut down their chlorophyll production, and their real pigments are revealed. These are averages so a frost could come a few weeks earlier or later than the stated dates.

For most crops that can be started indoors, seeds should be started about 6-8 weeks before your last spring frost date. This gives the plants ample time to grow large and healthy enough to survive their eventual transplanting to the garden. To keep informed about latest updates and possible zone adjustments, see the official USDA Plant Hardiness Zone Map website.

Check out these maps from the  North Carolina State Climate Office (NCSCO) for freeze information on your location. Notifications can be turned off anytime in the browser settings. Most of the vegetation is usually done for the year by then, and residents have to wait until spring to start again. Plain and simple, Charlotte usually sees frost for the first time from late October to the first third of November. See each plant's individual Growing Guide for more specific planting, plant care, and harvesting information. This means that on a really cold year, the coldest it will get is 10°F.On most years you should be prepared to experience lows near 15°F.

These charts can help you estimate when to expect the first frost in fall, and the last frost in spring, so that you know when to plant in your garden or meadow. Our spring planting calendar starts with the very first dates that you can plant (based on the last spring frost). You can turn to a few different sources to determine the average frost dates in your area, as noted.

Frost dates are calculated based on data from the NOAA National Centers for Environmental Information. A Hard Freeze Warning is issued when temperatures are expected to be 28°F or less. A Hard Freeze Watch may be issued a few days ahead of time if the potential exists for temperatures to fall into these thresholds. Below is a list of planting guides for Charlotte, NC.

The crops that should be started indoors are particularly susceptible to cold temperatures or have a very long growing season and need a head start. These include tender vegetables such as tomatoes, peppers, and eggplant and crops with a long growing season, like broccoli, cauliflower, and Brussels sprouts. Frost dates are important for gardeners to know, as they signal the start and end of the gardening season.

This information is useful both in terms of knowing when to sow seeds and the right time to plant annuals, perennials, trees, and shrubs that are likely to survive the winter. Use this map in combination with last and first frost dates to ensure you plant at the right time. Use our 2024 Frost Dates Calculator to find the average dates of the last light freeze of spring and the first light freeze of fall for locations across the U.S. and Canada. Regional last and first frost dates are an average estimate based on historical climate data and are not foolproof or exact. So in addition to knowing published frost dates, it's prudent to always be aware of your local weather forecast and be watchful for those nighttime temperatures.

Deeper valleys tend to have frost conditions earlier than the surrounding area since cold air sinks. Want to know when to expect your last frost of the spring, or the first frost of the fall? Enter your zip code (or City, State) below and we'll tell you what we know. Our information is taken directly from the National Weather Service and depending on the location of the reporting station for your zip code, the results may vary. The growing season, however, can end early once the first hard freeze or "killing freeze" happens to the area.

Here is some general info for USDA Zone 8a to help you get started.
