About Eddy County Weather
Eddy County experiences desert warmth
Eddy County's average annual temperature of 62.7°F sits well above the national median. This high temperature characterizes its semi-arid climate, which sees significantly more heat than the typical American county.
Ranking among the state's warmest
Eddy ranks among New Mexico's warmest counties, with an annual average nearly 8 degrees higher than the state mean of 54.8°F. Its consistently high temperatures define the southern Pecos River Valley experience.
Hotter and drier than neighbors
Compared to neighboring Lea County at 61.4°F, Eddy is slightly warmer and drier with only 12.8 inches of annual rain. It shares the intense heat of the Permian Basin but remains hotter than northern neighbors like Lincoln County.
Intense summers and mild winters
Summers are intense with 109 days hitting 90°F or higher and a July average of 81.4°F. Winters stay mild with a January average of 43.3°F and a light annual snowfall of just 2.9 inches.
Prepare for triple-digit heat
High-efficiency HVAC systems are essential here to manage over three months of potential triple-digit heat. Residents should prioritize water-wise landscaping, as the 12.8 inches of annual precipitation provides little natural irrigation.
