The year, day by day
Putnam works both ends of the calendar. Normal highs climb to 96°F by July 28 and hold at or above 90°F on 70 dates, then normal lows drop to freezing or below on 91 dates, bottoming at 26°F around January 5.
When the heat sits
Normal highs reach 90°F from June 22 through August 30, covering 70 dates. The broader mild season, normal highs of 70°F or more, runs April 15 to October 21.
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.
The freezing stretch
The normal low stays at or below 32°F into February 27, then returns to freezing around November 29, covering 91 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
July 24 carries the biggest normal gap between afternoon and dawn, 25°F between the normal high and the normal low.

Where Putnam Stands Nationally
Heat is a defining feature of the normals calendar — the normal daily high reaches 90°F on roughly 70 days a year, more than four out of five ranked stations record.
Putnam earns one nationally notable standing (outer quintile) against 6,860 NOAA 1991–2020 normals stations, middle-of-the-pack metrics stay silent here.
Monthly Precipitation
Average monthly rainfall
Putnam spreads its precipitation across the year
Neither half of the year dominates here: June through August take 34% of the annual total and December through February 11%, with neither reaching the 35% that would mark a distinct wet season. Putnam has no dry season to plan around, though it does carry a 44.9°F seasonal spread.
The gap between the wettest and driest month still matters: May averages 4.1" and February 0.9". The three wettest months together take 38% of the year, against the 25% a perfectly flat distribution would give them.
Shares are computed from this station's own 1991-2020 monthly precipitation normals. "Spread across the year" means neither the June-August nor the December-February share reaches 35%; it describes an average year, not the variability of any single one.

Data-derived climate profile
How Putnam's climate pattern fits together
heating led · moderate · mid swing
Putnam's energy balance leans toward cold weather: 3,903 annual heating degree days against 1,923 for cooling. Its 44.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Putnam's frost-free season lasts about 207 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Putnam's middle-range seasonal profile. The measured spread is 44.9°F. The annual average is 60°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
Putnam's 29.4 inches of annual precipitation falls in PlainClimate's middle band, so “wet” or “dry” is not the leading description. Snowfall is not added to the interpretation because its annual value is missing. Temperature balance and the calendar distribution carry more information than the annual moisture label alone.
These labels group NOAA 1991-2020 normals from Putnam'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 Putnam, not an official NOAA class or a year-ahead forecast.
