What is each month like in DeSoto?
NOAA's grid estimates the normals every 5 km or so from the stations around each point, terrain included. It smooths between stations, so night lows at the heart of a large city can run warmer than the grid shows: at five big-city airports we compared, the grid's highs were within about 1°F of the station and its lows 1-6°F cooler. The nearest record's high and low are beside each month.

What do the station records around DeSoto say?
Each row is a NOAA station's own 1991-2020 normals, with the snow and frost dates the grid does not give. A record downhill or nearer the coast than the city can run warmer, one uphill cooler: compare the elevations.

How much snow, how late a frost, what zone and how much sun in DeSoto?
NOAA's grid gives no snow, frost dates or records, so these come from the nearest station record, Grand Prairie (7 miles NW, 591 ft). NOAA publishes no snowfall normal for it; the nearest record that has one, Waxahachie (12 miles S), gets 0 inches a year. The last spring frost (32°F) comes after March 20 in half of years and the first autumn frost before November 13.
The USDA's 2023 Plant Hardiness Zone Map puts DeSoto in zone 8b (ZIP code 75115).
Over a year 79% of the sunlight that would reach the ground under clear skies gets through the clouds in the area (4.7 kWh per square metre a day, NASA POWER 2001-2020); July is the sunniest month (88%) and February the cloudiest (68%).
Grand Prairie's page has its months, frost probabilities, records by month and recent years. NOAA's grid has monthly figures only, so there are no day-by-day month pages for DeSoto; the nearest record's month pages have them.
