New Mexico mainly has a semi-arid to arid climate (Köppen climate classification BS/BW) with small areas of continental (Köppen Dfb) and alpine (Köppen Dfc) types. It lies in the Southwestern part of the United States of America. Oklahoma in the northeast, Texas in the east and southeast, Mexican states of Chihuahua and Sonora in the south, Arizona in the west, Utah in the northwest, and Colorado in the north, share borders with the state. The climate is arid in the west and south, while northern and eastern parts of New Mexico have alpine climates at high altitudes.
New Mexico, the Land of Enchantment, has an average elevation of 1741 meters above sea level. Wheeler's Peak has the highest elevation of 4013 meters in the state, while Red Bluff Reservoir is at the lowest elevation of 868 meters. The topography consists of vast deserts, high plateaus of rosy mesas, canyons, valleys, forests, and snow-capped peaks. The north has pastures and dense mountain wilderness, along with a section of the southernmost part of the Rocky Mountains. Mountain ranges and highlands, oriented north-south, divide the state longitudinally into three major areas. New Mexico is one of the Mountain States that forms the Four Corners region with Colorado, Utah and Arizona.
Summers are hot in the majority of New Mexico with low relative humidity. Daytime temperatures often exceed 100°F (37.8°C) at low altitudes below 1500 meters, even though the average high temperatures peak at 97°F (36.1°C) in July. Summer nights are usually comfortable due to rapid cooling after sunset and low humidity. Winter nights drop below freezing in many places, with a few even dropping below 0°F (-17.8°C). The days are warm and sunny, even at the peak of the cold season. Temperatures vary significantly across seasons and between day and night. The elevation is a more important factor than latitude to determine the temperature. Spring and autumn have warm temperatures and generally comfortable conditions.
New Mexico has scanty rainfall that averages 14" (355.6mm) in the year, with a peak during the summer. Southern desert receives less than 10" (254mm) of rain, while higher elevations in the state register above 20" (508mm). The sunshine is abundant, and the state averages 270 sunny days annually. Snowfall is heavy in the mountains and ranges from 60" (1524mm) to 160" (4064mm) in the winter. Northern and Central New Mexico register 20" (508mm) to 40" (1016mm) of snow, while the southern part is warmer and rarely records above 5" (127mm). The average relative humidity is low in the 30% to 50% range and seldom crosses 60%.

The best time to visit New Mexico
The best time to visit New Mexico is in the fall season from September to November when the temperatures are in the comfortable 65°F (18.3°C) to 85°F (29.4°C) range.

Additionally, June to August is the peak tourist season with costly flights and accommodations.
The worst time to visit New Mexico
The worst time to visit New Mexico is during the winter from December to February when the temperatures drop below freezing in many places. Snowfall is heavy at high altitudes, but even at low-lying plateaus, frost comes in to play. Winter days need sunscreen in many areas of New Mexico. Temperature varies vastly between day and night and drops rapidly after sunset. Mountain slopes often witness snowstorms in the winter. Skiing enthusiasts find excellent conditions for the sport in the Sangre de Cristo Mountains.
New Mexico is prone to thunderstorms, floods, and tornadoes in spring and summer, and snowstorms in the winter. Thunderstorms are frequent in late spring and summer and bring most of the rainfall. Flash floods occur after storms as the sparse vegetation, and uneven terrain in many areas is unable to hold even moderate amount of water. Dry arroyos overflow banks and halt traffic for several hours. The melting of snow from April to June and occasionally heavy rainfall may cause flooding of large rivers. Tornadoes sporadically hit New Mexico from May to August but rarely cause damage to life and property due to the sparse population of the state. New Mexico has an average of nine tornadoes in a year.
Weather in January
January is the coldest month of the year in New Mexico as the night temperatures remain in the freezing zone. The bottom may hit extremes below 0°F (-17.8°C) in the upper mountain ranges but generally keeps above it in the rest of the state. The average low temperatures are in the frigid 2°F (-16.7°C) to 35°F (1.7°C), while the average high temperatures are in the 38°F (3.3°C) to 54°F (12.2°C) zone.

The combination of snowfall, cold nights and warm sunshine is a boon for activities like cross-country skiing, snowshoeing, mountain biking, and camping. Snow thaws rapidly in the lower plains, and the trails display a combination of black, brown, and white colors. Many state parks have large boating lakes with warm waters during the spring days. Woodland forests see blooming of flowers, while the trails below are full of wildflowers that arise from the winter slumber.
