What is each month like in Spring?
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 Spring 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 Spring?
NOAA's grid gives no snow, frost dates or records, so these come from the nearest station record, Houston (6 miles S, 95 ft). It gets 0 inches of snow in a normal year. The last spring frost (32°F) comes after February 13 in half of years and the first autumn frost before December 9. Its record high is 109°F (2011) and its record low 5°F (1930), on the National Weather Service's long record for the area (kept since 1888).
The USDA's 2023 Plant Hardiness Zone Map puts Spring in zone 9b (ZIP code 77373).
Over a year 77% 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); October is the sunniest month (83%) and February the cloudiest (66%).
Houston'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 Spring; the nearest record's month pages have them.

How does the climate vary across Spring, ZIP code by ZIP code?
One ZIP code area lies wholly or partly in Spring. Each row also names the nearest station record and its frost dates.
