Frost risk through the year
How sure are these dates?
A frost date is a probability, not a promise. NOAA worked out, from 30 years of nightly lows, how often the last spring frost and the first fall frost fall on each date. The middle column is the typical year. The outer columns are the early and late years that come about once a decade.
| Early year 1 in 10 | Typical year 1 in 2 | Late year 1 in 10 | |
|---|---|---|---|
| Last frost in spring | February 16 | March 8 | March 29 |
| First frost in fall | November 6 | November 22 | December 9 |
The frost-free season between them runs 258 days in a typical year. In 1 year in 10 it is 285 days or longer, and in 1 year in 10 it is 231 days or shorter.
- Hard freeze (28°F): typically last on February 21 and first on December 6. It is a harder freeze than the 32°F frost line, cold enough to damage many garden plants; how hardy a crop is decides whether it comes through. (The National Weather Service's own hard-freeze threshold varies from office to office.)
- Frost possible (36°F at the station): typically last on March 24 and first on November 11. On clear, still nights the ground can be several degrees colder than the thermometer, so frost can form on plants when the official reading is in the mid-30s.
In 8 springs out of 10, the last frost in Tyler comes between February 16 and March 29, a window of 41 days. That is wider than at most NOAA stations (the typical window is 31 days), so spring here is less predictable than average: lean toward the later date.
Among Texas's 387 NOAA stations with a frost every year, 74 percent have their typical last frost later than Tyler does.
Planting calendar for Tyler
These dates count from the typical last and first frosts, using the planting rules published by Colorado State University Extension (spring), Virginia Cooperative Extension (fall crops) and University of Minnesota Extension (garlic, where winters are hard). Weather in any one year can run early or late, so check the forecast before you plant tender crops.
We don't give a garlic date here. The rule we use, from the University of Minnesota Extension, counts from the first killing frost, and it works where a hard freeze comes every year before the ground freezes. Your county's extension office can tell you when to plant garlic in your climate.

Want more insurance? Shift every spring date 21 days later. That plans around March 29, the date after which only 1 spring in 10 has a frost.
For spring bulbs such as tulips and daffodils, plant once the soil has cooled to about 50 to 55°F and keep going until a couple of weeks before the ground freezes. Our guide to fall planting explains how to tell.
Where these numbers come from
These dates come from NOAA's weather station Tyler Pounds Field (station USW00013972), 6 miles from the center of Tyler. It sits at about the same elevation, 540 feet above sea level. NOAA rates this station's record as representative: at least 10 of the 30 years, with the gaps filled from nearby stations.
Our ZIP code lookup matches these 6 ZIP codes to the same station, so they get the same dates: 75704, 75706, 75709, 75754, 75756, 75758. Hardiness zones are worked out separately for each ZIP code.
