Which months are mildest at Mercury (3 mi SSW)?
Normal highs sit between 65°F and 85°F in March, April, May and October. Of those, May 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.

How many heating and cooling degree days does Mercury (3 mi SSW) record?
A normal year at Mercury (3 mi SSW) brings 2,955 heating degree days, 45% fewer than the median U.S. place (5,373), and 2,240 cooling degree days, 2.5 times the median (908). Five months need 300 or more heating degree days, a monthly mean of about 55°F or colder. For gardens and crops, NOAA counts 5,421 growing degree days a year above 50°F.

Which places near Mercury (3 mi SSW) share this climate record?
Indian Springs has no NOAA station with 1991-2020 normals of its 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.

Questions about Mercury (3 mi SSW)'s climate
What is the coldest month at Mercury (3 mi SSW)?
December, with a normal high of 54°F and a normal low of 32°F. The warmest is July (100°F by day, 71°F at night).
Does it snow at Mercury (3 mi SSW)?
Yes. NOAA publishes no 1991-2020 snowfall normal for the station; the nearest record that keeps one, Mercury Desert Rock Airport (0 miles away), records 1 inches of snow in a normal year.
What is the rainiest month at Mercury (3 mi SSW)?
February, with 0.99 in of precipitation in a normal year; the driest is June with 0.14 in.
What plant hardiness zone is Mercury (3 mi SSW) in?
The USDA's 2023 map puts Mercury (3 mi SSW) in zone 8b in ZIP code 89060, the nearest ZIP area. By the same method at the station, the coldest night of a typical year reaches 20°F (16 years, 1991-2020): zone 8b.
How late can frost come at Mercury (3 mi SSW)?
In half of years the last 32°F night comes after March 10; in one year in ten it comes after April 8. Waiting until April 8 leaves about a one-in-ten chance of a later frost.
