Carthage, TX Climate

Climate Insight: Carthage, TX

An annual average temperature of 65°F, ranging from a mean daily high of 76°F to a mean daily low of 55°F is what the NOAA 1991–2020 climate normals report for Carthage, Texas. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00411500 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.

On PlainClimate's composite comfort index, Carthage scores 87/100 (Excellent), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above turn that into a planning tool: expect the mildest highs and lows in the shoulder seasons, July-driven heat at the peak of summer, and January-driven cold at the depth of winter. Every number here is a thirty-year average, not a forecast, so any given year can and does run warmer, cooler, wetter, or drier than the normal.
