About Phillips County Weather
Phillips runs warm with above-average moisture
Phillips County's 48.9°F annual temperature exceeds the U.S. median of 47.5°F, while its 17.9 inches of precipitation sit above the national average. This combination creates a semi-humid plains climate, relatively wet for northeastern Colorado.
Warmest tier, above-average precipitation
At 48.9°F, Phillips County ranks among Colorado's warmest counties, sitting 2.9°F above the state average of 46.0°F. Its 17.9 inches of annual precipitation actually exceed the state average of 16.0 inches, making it one of Colorado's wetter plains counties.
Twin-like climate to Montezuma and Montrose
Phillips (48.9°F) sits nearly identical to Montezuma (48.8°F) and just 0.7°F above Montrose (48.2°F), but its precipitation of 17.9 inches surpasses both neighbors significantly. This extra moisture creates slightly greener plains than its western counterparts.
Moderate summers, cold snaps, manageable snow
Phillips averages 70.7°F in summer with 40 days of 90°F-plus heat—notably higher than Montezuma but lower than Morgan's 58 days. Winter averages 28.1°F with 30.4 inches of snow, making it moderately snowy with respectable precipitation year-round.
Balanced climate calls for moderate HVAC prep
With 40 extreme heat days annually and 17.9 inches of precipitation, Phillips residents need solid air conditioning but benefit from the extra moisture reducing dust and fire risk. Standard snow removal equipment suffices for 30 inches of annual snowfall, and the relatively balanced climate allows year-round outdoor planning with seasonal adjustments.
