Grant County New Mexico is one of the most diverse landscapes in the southwest US, with half a dozen climatic regions to be found and an incredible variety of vegetation, weather and temperatures — sometimes over the space of just a few miles!
Silver City is 6,142 feet above sea level. Elevations range from 4,000 above sea level in the high desert at the southern end of Grant County to mountains reaching over 10,000 feet in the north.
The Silver City climate is noted for its clear mountain air, low humidity and four gentle seasons. The annual average temperature is fifty four degrees Fahrenheit, with mid-summer days in the eighties. Pleasant, above-freezing temperatures most of the winter provide near-perfect conditions for day and evening activities. The average annual rain/snow precipitation is just over fourteen inches. On average, the sun shines more than three hundred days per year, and there are at least one hundred seventy four growing days.
Over the course of a year, the temperature typically varies from 27°F to 92°F and is rarely below 20°F or above 98°F. The warm season lasts from May 22 to September 9 with an average daily high temperature above 84°F. The hottest day of the year is June 24, with an average high of 92°F and low of 63°F. The cold season lasts from November 20 to March 1 with an average daily high temperature below 60°F. The coldest day of the year is December 23, with an average low of 27°F and high of 53°F.
Each winter brings one or two snow storms to the County, although it is unusual for snow to persist on the roads in the southern and central part of the county for more than a day, and snow accumulation of any amount in the south is not common. Area schools occasionally have snow-day cancellations, although these seem to be far too few in number for the students’ liking.
The northern tier of the county and places elsewhere in the county above 7,000 feet can have snow on the ground for several days or more. The Burro Mountains, while quite close to Silver City, often have snow cover for several days at a time, as do the mountains east and north of Silver City.
