The year, day by day
The year in Philadelphia runs from a mild 35°F around January 17 to 92°F at the peak near July 27, and the normal low never reaches freezing on any date in the record.
When the heat sits
Normal highs reach 90°F from June 24 through August 28, covering 66 dates. The broader mild season, normal highs of 70°F or more, runs March 22 to November 5.
This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.
No freezing date
Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 35°F around January 17.
The widest day
October 21 carries the biggest normal gap between afternoon and dawn, 26°F between the normal high and the normal low.

Where Philadelphia Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 66 days a year, more than four out of five ranked stations record.
Philadelphia earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.

Data-derived climate profile
How Philadelphia's climate pattern fits together
mixed demand · mid swing
July and January mark the typical warm and cold ends of the calendar in Philadelphia's middle-range seasonal profile. The measured spread is 35.6°F. The annual average is 64°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Heating and cooling both register in Philadelphia's normal, at 2,444 and 2,174 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.
A roughly 234-day frost-free season sits inside this mixed heating-and-cooling profile. Start and end dates matter because both sides of the thermostat register during a normal year.
A moisture-range label is withheld because Philadelphia'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 Philadelphia's primary station, where heating and cooling demand are close enough that neither season sets the character on its own. On a balanced station like Philadelphia, the bands are descriptive ranges rather than an official NOAA classification or a forecast.

Data Sources
Data source: NOAA U.S. Climate Normals v1.0.1 (1991-2020). All figures on this page are from Philadelphia's primary station: PHILADELPHIA 1 WSW (USC00226894). 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 2856960). Match rule for Philadelphia: 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 Philadelphia comes from its primary NOAA station record.
