The year, day by day
Summer here tops out rather than builds: the warmest normal high is 81°F around July 18, short of 90°F on every date, while 168 dates carry a normal low at or below freezing, the coldest 11°F near January 28.
The freezing stretch
The normal low stays at or below 32°F into April 17, then returns to freezing around November 2, covering 168 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
September 4 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Data-derived climate profile
How Oil City's climate pattern fits together
heating led · mid swing
Oil City's energy balance leans toward cold weather: 7,532 annual heating degree days against 360 for cooling. Its 48.2°F seasonal range still makes the monthly rows more useful than the annual average alone.
Only about 137 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 January mark the typical warm and cold ends of the calendar in Oil City's middle-range seasonal profile. The measured spread is 48.2°F. The annual average is 45°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Oil City'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 Oil City'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 Oil City, 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 Oil City's primary station: OIL CITY 2S (USC00206080). For informational purposes only.
Place identity: U.S. Census Bureau 2024 Gazetteer places. The conservative exact name-and-state crosswalk finds no Census place match, so PlainClimate treats this as a station-mapped location and does not claim it is a municipality. No exact Gazetteer row for Oil City; facility counts that depend on place identity are therefore an upper bound, not a municipal census.
On this page every temperature, precipitation, and derived score for Oil City comes from its primary NOAA station record. No figure on this page is typed in by an editor - each value is rendered from NOAA 1991-2020 U.S. Climate Normals.
