When is the best weather to visit Big Spring?

Normal highs sit between 65°F and 85°F in March, April, October and November. Of those, November has the fewest days with rain (3).

That is a measurement, not a recommendation: it counts the months whose normal afternoon high sits between 65°F and 85°F, where a light layer is enough by day.

When is the last frost in Big Spring?

In Big Spring, the last spring frost (32°F) comes after March 20 in half of years and after April 7 in one year in ten; the first autumn frost comes before November 13 in half of years and before October 31 in one year in ten.

First autumn frost, half of years before
November 131 year in 10 before October 31; 9 in 10 before November 29

NOAA puts the median frost-free season at 239 days, and the season without a hard freeze (28°F) at 261 days.

A hard freeze (28°F) comes after March 6 in half of springs and before November 24 in half of autumns.

The USDA's 2023 Plant Hardiness Zone Map puts Big Spring in zone 8a in ZIP code 79721, the nearest ZIP area. By the map's own method, the average of each year's coldest night over 1991-2020, Big Spring's NOAA station is in zone 8b: the coldest night of a typical year reaches 15°F (25 complete years); the map interpolates between stations and terrain, so the station and the ZIP area can differ by half a zone.

Which places near Big Spring share this climate record?

4 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.
