The year, day by day
Summer here tops out rather than builds: the warmest normal high is 88°F around July 13, short of 90°F on every date, while 187 dates carry a normal low at or below freezing, the coldest 13°F near December 20.
The freezing stretch
The normal low stays at or below 32°F into April 19, then returns to freezing around October 16, covering 187 dates in all.
Derived from the normal daily minimum. This is a different measure from the 50%-probability frost dates shown elsewhere on this page, which come from NOAA’s frost product.
The widest day
October 6 carries the biggest normal gap between afternoon and dawn, 36°F between the normal high and the normal low.

Data-derived climate profile
How Parker's climate pattern fits together
heating led · mid swing
Parker's energy balance leans toward cold weather: 6,048 annual heating degree days against 510 for cooling. Its 41.0°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 147 days are frost-free in a normal year. That short interval is consistent with the cold-season signal, but the measure does not predict the exact first or last freeze in any one year.
July and December mark the typical warm and cold ends of the calendar in Parker's middle-range seasonal profile. The measured spread is 41.0°F. The annual average is 50°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Parker's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.
These labels group NOAA 1991-2020 normals from Parker's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Parker, not an official NOAA class or a year-ahead forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Parker's primary station: PARKER (USC00056323). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as an incorporated place (GEOID 0857630). Match rule for Parker: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Parker comes from its primary NOAA station record.
